I'm not sure how many people have been benefitting from you threads but I must say that you rock!
I'm working on a Desoto 291 for my "A" and you have unearthed a treasure chest of knowledge and information for all to share.
Thank You!

With my unofficial count of 73 Hemi owners and 150ish Hemis here on the HAMB, I would say that the Hemi tech threads are more than worth the effort put fourth and very much appreciated. Thanks! Axeman39.

Thanks guys!! I appreciate the nice words! I'm glad they're helping someone. I know they're certainly helping me!! I've been spending so much time just trying to get the subjects up that I've hardly had time to even read them! I'm excited to sit down and start taking notes myself. The HAMB rules and with the amount of Hemi knowledge on here the HEMI Tech threads should rule too!

Thanks for the help gathering info everyone! We still have a long way to go!

BTW... This isn't just for Chrysler FirePowers! We need info on Dodge, DeSoto, the poly motors, the small cube Hemis... EVERYTHING!

Default Re: HEMI Tech- INDEX

Just wanted to bump this up for you guys. I added a couple catagories for your viewing pleasure. It will take some time to get all these catagories filled out, but the topics are started. If anyone thinks of a topic that's NOT coverd here, let me know or start it with "HEMI Tech- xxxxxxxx" and I'll add it to the "Index". Just check to make sure it's not covered. Had some thoughts of some other ideas like Video rentals and things of that nature for resources. Have to figure out how to handle those yet. Not sure if that will be addressed in these or not.

We'll get there!

In the mean time, check out Harmonic Balancers and Identification and see if there is any factual information you can add!

Cheers!

Just wanted to bump this up in case it hasn't been seen yet. Let me know if there is any way I can add or improve what's already been started.

Also... there are some subjects still virtually blank. If there is any info anyone can add to those sections, please do so. This seems to have been a great thing for anyone needing Hemi info thus far...

Bumping the Index back up to the top since there has been a lot of Hemi talk lately. Still trying to keep these updated. If anyone sees information that can be linked to under these topics, please add it.

THANKS!

Going to bump this up so you guys can take a look at the topics and see if there's anything we can add. We have very little in several catagories. Amazingly the HEMI Tech- Examples and specs!
has very little in it. Hopefully those of you with Hemis completed or in the works can kick us down some pictures with specs. Maybe even links to your build or something.

Thanks guys!

Going to bump the Index back up to the top. I updated the intake/exhaust thread with a link to some Offy 6x2 stuff. Maybe some of you will have some fresh new thoughts and info to add somewhere to some of the other topics involving Hemis.

Keep the info coming! Some of these topics are looking pretty bare and need more discussion.

Cheers!

Thread the flange for 1/2-20 and use bolts instead of the oem bolt/nut setup.

Check with HH they have the fex plate bolts which are 7/16 with nuts or the 1/2-20 for tapped cranks. You can tap your crank to use the 1/2-20 the holes are the right size to run the 1/2-20 tap through. Just make sure they are tapped straight.

Hey guys, drop these questions and answers about flexplates here:

These are good questions and good answers, but won't help too many people here. Better posted here. THANKS!

Well... we haven't talked about Hemis enough lately... so let's see bump this Index back up so you guys can add to some of these threads where possible.

Been thinking about adding a reference for machine shops in everyone's area going state by state. Please let me know what you guys think about it. Last time I brought it up it got a good response, but it was brought up very unofficially. So shoot me a PM if you think it's something worthwhile or bump this back up.

Also, I still haven't done much with feature builds for this section and I've been seeing some very nice progress on a few builds. I may need a kick in the rear or a reminder of who's building what so I can get some featured Hemi builds up for everyone's reference and reading pleasure!

Thanks everyone!

I was doing a search back in 2004 on hotheads swap meet forum for shops in my area SE Michigan and got a few hits which are Thomson Automotive in Redford, Mi (313-538-0044) and also Dowker engines in Charlotte, Mi (517-543-0249) and one finale one is Angelucci Performance Macomb, Mi (586-412-8442) I personally have not done business with any of them just wanted a source if I did need one down the road.

Thanks man! It looks like I better start a thread on this so there is a set place to post this info. I'll do it state by state in a few. The thread will probably get VERY big. Let me think about the best way to handle all the info that will be posted. Maybe I'll do it by alphabetic sections or something. It will take a lot of effort to get it filled out and will take everyone's support here. I will get started on it though.

Thanks!

HEY BOB!!! Welcome to Hemis!!

Yeah, hopefully I'll make it out to the RRR. Would be good to catch up!

Oh... there are quite a few good places for Hemi machining in you area. Just can't remember the names. When you find out, PM me the details so I can post them in the Nevada section of the resource list.

Cheers!

Okay, it's 2008 and 2007 was a good year getting all this together. WE NEED MORE INFO! Desoto Hemis and Dodge Hemis are hardly discussed and I know there are plenty of people out there that have them that can add info to the catagories. Let's keep it going. We're all here as students so anyone that can teach, please stand up so we can learn more about Hemis!

Please, if you have experience and knowledge with any breed of early Hemi, take a little bit and read through the various catagories and add what you know.

Hoping to see more examples and build ups this year. There's a 331 in the works right now that I'm hoping to do a build-up thread on, or at least a build-up series on. Bored&Stroked dropped all our jaws with a build up and hopefully we'll get to see that wrapped up and maybe we can even see some video action from him on the build! (hint, hint!)

BTTT for 2008! Thank everyone for your participation and help keeping the catagories going!

Okay boys and girls... bumpin' this up again.

Anyone building a hemi this year? Post it up in the examples or post up a build sequence and shoot me the link and I'll make sure it gets added in the right places.

Word has it that I just might be able to get a build progress on two 331's at the same time. Hopefully that will work out. I'll keep you guys posted.

Mine is in the machine shop as we speak, getting the block and heads prepped. I dropped the new valves off friday so it should be done late this week or early next. Everything is built and/or bought for the rebuild and sitting in my office. Then my build up will start. It will be a moderate street motor, not to outlandish since it goes in a 2000lb bucket.

If you have the time, PLEASE do a pic progress on the build! I'm more than positive that others (as well as myself) will benefit from it!

Can't wait to see!

This I found on thehemi.com
Did anyone here did this swap?


Kenneth has discovered that by honing the lifter bores (assuming one needs or wants to) approximately 0.017 inches you can now use 1986 Oldsmobile roller lifters. Although this will require the alignment bars to be fabricated, or finding something that will fit. Kenneth is a machinist by trade, so was able to fabricate his own, and is also fabricating his own spring-style retaining device(s). These rollder lifters are considerably cheaper (approx $9 each) as compared to name brand aftermarket parts.

Hey guys! It's been awhile since I've bumped this up. I've been crazy busy and I'm honestly very behind on keeping this up to date. There's been a lot of builds worthy of mentioning as well as some great stuff coming up on the board that should be linked in the related topics.

BTTT... If anyone has anything to add to the topics, send me a PM if it needs to be added or link it up under the correct topic. Seems like early Hemis are getting more popular every day! We still have a TON to add here that has NOT been covered.

Still looking for people's build progress posts as well as people doing progressive build TECH on their Hemis.

Now get back to work on your Hemis!

Thanks for looking and participating!

Cheers!

Default Re: HEMI Tech- INDEX

Okay guys, I've been going through some of the threads on here and I see that I REALLY REALLY need to add a few catagories to the Index including a specific catagory for Industrial and Marine applications. Tons of inquiries on that lately.

Awhile back the boss made a change that eliminated the "EDIT" button and it was never restored. When it's back I will go through all these threads and get things up to speed. I'm overdue and I appologize for that. There has been a ton of new threads that should be linked up in here that are very valuable to the content of this little HAMB school for Hemis.

Since I'm bumping this up, can you guys please add here, any catagories you might like to see covered that haven't been touched on? Also, any suggestions on things that should change?

Thanks for your help guys/gals!

Still getting the PM's with the ideas and input to the above ^^^^. Please post them here so everyone can see them.

One of them discussed awhile back was with Limey Steve and his Daimler Hemi stuff. Here's an example thread to get you guys thinking...

We're all here as students so anyone that can teach, please stand up so we can learn more about Hemis!

Please, if you have experience and knowledge with any breed of early Hemi, take a little bit and read through the various catagories and add what you know.

Hoping to see more examples and build ups this year. There's a 331 in the works right now that I'm hoping to do a build-up thread on, or at least a build-up series on. Bored&Stroked dropped all our jaws with a build up and hopefully we'll get to see that wrapped up and maybe we can even see some video action from him on the build! (hint, hint!)

BTTT for 2008! Thank everyone for your participation and help keeping the catagories going!



I'll have a few pics of mine coming up here in a few days...
Long block is assembled and and have the intake and mag mocked up...
FYI.......060 over 291 Desoto........

That does not sound good...

Hope it helps! If not, just post up a thread and we'll help you out.

Glad to see more people are using this lately. Seems like there have been a TON of Hemis for sale and tons of threads with questions related to them.

We STILL need more DeSoto and Dodge tech folks! Add knowledge to the topics where you can! Keep it coming!

I still haven't been able to edit this thread, so I'm just going to add this link to the end for the time being. Some really great images/renderings of early Chrysler brochures. Thanks Cross Rodder! Once I can edit this, I'll add a catagory to support this information and clean up this thread.

Enjoy!

Okay guys! I have some editing rights back, but I've been informed the rights might go away in the future depending on changes that may come to the HAMB. To be safe I've added a "Social Group" just to capture and make it easier for me to edit and moderate the content. That means no drama, only facts and discussions!

Be patient with me while I get caught up one everyone's input from that past few months. It's going to take me a little bit, but I want this to really expand and grow with the HAMB.

Check it out!

Bump up the topic on Crankshafts or start a new thread regarding the topic and someone should have a solution for you. Sounds like a great topic. If you start a thread I'll link it to the crankshaft section.

Thanks and good luck!

There are considerable differences between the pass car and marine cranks at the snout. The marine piece could be welded up and machined to look like the pass car part but it may be cheaper to just replace it. I'll try to post a pic later unless someone has a marine crank sitting out and can do it sooner.
...and don't forget to plug the oil feed coming out the front end....

I started a marine crank thread, you can punch me in the face if I know how to link it though. It's called Hemi Marine Crank Ho Down.

I added a new, more focused topic on just gaskets. This might help clear up a few differences in heads gaskets, intake, etc..

I am, as we speak, putting together a blower intake for a DeSoto Hemi. I'm starting with a generic, cast, aluminum blower intake top half from Dyers. I was originally going to mate it to my Stock 291 4bl intake using a 3/4" thick base plate with the top half, but I have since traded the cast iron 4bl intake for an aluminum 2X2 intake. The 2x2 intake is aluminum (BIG weight savings), will give better distribution, and will provide a better bearing surface to mount the base plate too. If anyone is interested, I will take pictures as I do it...

OF COURSE we're interested! Get a thread going for it and drop a link under the blower section of the Index. That will be good information.

Here's a couple of trivia facts I leaned on my 392 while doing a cam swap.

1. If you remove the rocker shaft bolts to remove the pushrods, there's nothing holding the heads on the engine.

2. Hemi heads make a loud noise when they hit the floor.

Ask me how I know.

It was on an engine stand and was rotated a few degrees. The head on the "high" side stayed on the dowel pins just fine. But the head on the side that was rotated kinda downward seemed to be quite happy jumping onto the floor.

Seems like something as awesome as a hemi would have more than just 4 bolts per cylinder holding the heads on. Heck a sbc has almost double the number of bolts holding it on. 10 bolts for hemi vs 17 bolts for Chevy.

Oh well, no harm done and I learned something new.

Very little in the way of 'special' tools are required. That said, if you use adjustable pushrods, you will find it extremely handy to have a couple of purpose bent end wrenches to get into the restricted space.

Good thinking though! Thankfully nothing special required. If you (or anyone else) DOES find something specific or helpful, please drop it into the related topic of where it would be used!

Glad people are throwing ideas out there for topics! I appreciate it! All feedback is appreciate and hopefully you guys keep it coming. Thanks!

A quick thanks to scooter for setting up these tech threads! Having just acquired most of a '55 C300 331 Hemi, I'm gathering all kinds of info which is great since I've never own a Hemi before. Now I'm just gathering parts as I can afford them. thanks to robert1 for the oil pump and filter!

Keep these threads going!

Default Hemi spark plug insulator dimensions

Can anyone tell me the length/height of a spark plug insulator for the 426 Hemi?

I am running a 325 KD-500 Dodge in my track roadster and in order to run modern thickness ignition wires the builder fabricated spacers to create more room under the covers. Thus, a longer or taller spark plug insulator might work well if it's not too long.

Thanks,
trakrodstr

I THINK the Hot Heads Site has the measurements for the spark plug tubes...

Thanks 345 DeSoto,

I was asking about the insulator/connector that fits over the spark plug and attaches to the ignition wire.

By the way I have two DeSoto Hemis. One is a 330 drag race engine that was assembled in the 70s and never started. It has zoomies, Hilborns, some really high compression Venolia "pop-up" pistons and who knows what cam. The other is a DeSoto Industrial Hemi, 276, that was used as a water pump engine on a forestry fire truck. I also have a NOS billet steel Moldex crank that was ordered for a racing hydroplane but never used.

I dream of an extreme hi rev small DeSoto Hemi with the crank completely tricked out....maybe someday.

cheers,

trakrodster

I think all the high deck hemis use the same oil pump, @ least according to Leo's book.

Here are some tid bits of oil pump info...I have also put this in the OIL System folder.
Dodge started out with what we generally consider to be the '392' pump.
Chrysler started out with what is generally called the 'early style' pump.
...and then there is DeSoto...
DeSoto used the design of the early pump, but, they used the 'foot' design of the Dodge. So what you have is an early style pump that will bolt on to a Dodge or a 392. Conversely, you can put a new M-50 on your DeSoto, of course the pick-up tube must be dealt with but, hey, were fabricators, right? Also, the DeSoto shaft is about 0.100" shorter than the rest so some fussing is required if you swap things around.

276-291 DeSoto on left, 331 Chrysler on right, note the casting numbers.


The feet sure 'look' the same...


time to get the tape out...DeSoto


331...


392...


Hopefully I have been able to offer some additional confusion to the issue..

Gary

I have a early hemi I recently purchased (my first) and the seller described it as a 1958 Dodge 354 Hemi out of a dump truck. I finally got it apart (with alot of patience, 2 cans of PB Blaster and heat,. wheew) and it looks like has never been gone through before.

Headed to the machine shop but wanna make sure I'm on solid ground with the ID.

Valley casting number is # 1619829-7 and number stamped on the front of the left bank is VT576.

Any help??

Thanks, jeff

Jeff, take a look at the ID thread linked above. You will find plenty of info on that number. At first glance, it does appear to be a truck number.

Sweeeett!! That thing is niiiice! Make sure to add a video to your progress!

Glad the tech helped! I have been SUPER busy around here, so I've fallen behind on the organization of it all. I have a bunch to add, including a BUNCH of info on Daimler Hemis, and some much needed links.

In all seriousness, though. This tech is NOTHING without all who have added to it! Keep adding to the tech as you see good links out there!

Thanks, the link is awesome. I dropped the short block at the machine shop here locally this morning,. I've got the heads that came off of the 354 engine which appear to be truck heads with the "tall" heat passages and second set of 392 passenger heads.
I want to run a 2x2 edmunds intake but the 354 truck heads with the tall heat riser passages in the center arent covered by the intake. In the link you sent me it says the 392 heads will work on the 354 short block but I cant use my edmunds 2x2,. Sigh,. Seems like there should a way,.

A good welder could weld up the upper part of the crossover, or use a block off plate. The Edmunds(that I'm aware of) is made for the small port 331s. See how they match up. There are a number of problems trying to use 392 heads on a 354 block.

One piece intakes will not fit if you have tall deck (392) heads on a short deck (331-354) block.
The Edmunds were made for both the small port (51-53) and big port (54) heads. Which do you have? IIRC, all Edmunds have a t-stat so you need to check port size to determine which head matches the intake. You could run the small port intake on large port heads, been done many times, just not the most efficient.
You can still use the truck heads, there are two relatively easy solutions, but you will still have water in the manifold:
...Weld a tab onto the intake to cover the port.
...Once the heads have been cleaned, fill the top portion of the port (in the head) with Devcon or something similar.

This discussion needs to be moved to a project thread.
