DeSoto Cam And Roller Lifter UPDATE

Really good info here. I read all 120 posts and I don't think this was answered. I have a 330 Desoto with a fresh re-grind for hydraulic flat tappet lifters. Now that these lower cost rollers are easy to get, can I run these rollers instead of the flat tappets on this cam? It would save the 2500 rpm break-in drill.

 

No.

 

PANIC must be Irish! You ask him a SIMPLE question & he just talks & talks! LOL

 

I'm Irish. So talk to me! The rollers need a billet cam? Is this a metal type problem? Will rollers wear out cast cams?

 

OK ....I think I know this one. The rollers are steel and cam is cast . Not a good combination as the harder steel component will over time wear on the softer cast conponent. Roller cam shafts are steel thus being compatable with the steel rollers.

 

No, the roller lifter requires a completely different lobe design. There is zero compatibility.

Ha ha guys She wants to know is that “MAMMA” as in “throw momma from the train” or “big momma’s house” either way got me smiling
Rat now has his manifold and hopefully he is a happy camper.
I have been totally distracted over the past few months started with moving house but ended with some health issues ( will not go into that here)
Keen to get one of these cams and a set of roller lifters. Can anyone provide me with some specs on the cams are they readily avalible?
Cheers
Peter

Hey Ward...I know, Ive emailed Pete heaps of times but no dice as hes been busy moving house.

Its a very very nice intake/casting which is why I want one.

Last i heard he was back into it having set up his new shop but i still cant get any answer from him as to the timing of a blower intake (and I NEED one)

Pete if you see this thread, let us know what youre up to champ !!

[/QUOTE]DeSoto cams tend to not be redily available, but, someone posted here in the regular forum & @ Hot Heads that they had some DeSoto blanks for sale.

 

Wow, what a great thread. Cam/lifter combo has been a lingering issue in my mind, planning for a 33/341 build (WHEN I finally get lucky enough to locate a rebuildable and the dough). I've re-read this whole thing again, and YOU GUYS ARE GREAT! You really talked this through AND (as usual) were patient with Qs from those of us way less knowledgable about the internal details of the early Hemis. Since I hope for reasonable hp/torque BUT a long-lived build, you have convinced me that a modern lifter & cam combo are the best for me. For my part, I want to THANK everybody for their time and trouble. THIS is why the HAMB is the bomb! Straight answers, honest debate, alternatives discussed, comparative advantages/disadvantages, suppliers and product quality, etc. Salute!

Sep. matter: Rat, where did the intake finally turn up??? Glad you found one, man!

 

are these the steel billets that he's been able to do for any engine and they have a bronze gear that wont last very long ? i guess he can install a cast gear from your old cam and then its something for the street that will last. did he give a price for what a solid roller is ?

 

Time to get this back in the lime lite...FSI, did you resolve you questions about gear material?

Tony, Rat, Ward, Budd, how about some updates?

For any one interested, I have several sets of Mopar oem, used rollers, links and spyders for sale. Send a PM....

DOGPATCH

Flat tappet cams have the lobes cut on a slight angle to rotate the lifters. Roller cam lobes are ground flat so that the lifters don't try to rotate...

 

So here it is November 2010, does this firm still offer steel Hydraulic roller camshafts for low deck desotos? I am in the process of researching parts for a 276. I have no experience with reground cams, and would very much like to switch to rollers.
I tried calling the number listed for Contreras Cams today but no answer, of course, because its a holiday. I was hoping I would catch an recorded number though.

 

still should be a good number...

 

hows your car running now 345 Desoto?

 

Like a fine watch...

 

I am lookinng for a roller cam for a 354 and have found alot of great information on this site, but have had very little luck finding information on the internet for either CONTRERAS CAMSHAFTS or CHET HERBERT CAMS. Can anyone tell me if either of the companies are still on business and some current contact information?
Thanks for the help

 

First off, you will likely get your balls whacked for not doing an intro. Please read the rules.

As for the cams, did you try the phone number in post #132?

.

 

73RR sorry for the mistake guess I went through the rules too quickly. I have tried the Chino number (909-597-5950) and there was no answer, but it is Easter. I did also find on internet search an Anaheim phone number for Contreras Cams (714-533-6033) and did get an answering machine with greeting for Contreras. I will confirm that they have moved when normal busness hours resume and update this thread with address and number.

 

The cam company is still near/at Herbert's place, but Nachi commutes from the San Francisco area weekly. Don't think he's planning on moving the company.

 

I've seen a lot of print about roller lifters and retro roller lifters. None of the verbage I see comes right out and explains it. If I get retro roller lifters for my big block rebuild, do I have to get a roller cam?

 

Yes, roller lifters are designed and meant to be used on a roller cam.

 

There are drastic differances in ramp design between a flat lifter and roller lifter lobes.

 

...completely different lobe design...

.

 

Have really gained alot of great information and done alot of reading, but if I've missed something please let me know. thanks for all the help.
Starting at post 102 inn this thread back in 2009 a few members had purchased or were going to purchase maxspeedingrods brand hyd. roller lifters for Chrysler LA (273-360). The link to the Bay is still good, the price is still good, but my aquestion is has anyone that has used these lifters have anything good or bad to say about them?
Thanks

 

DO NOT buy those Max Speeding Rods lifters!!!!!!!!!!!!! A week after I installed them in my engine, they disintigrated!!! I wound up buying the Lunati version of the same lifters, and they're bulletproof...

 

345 Desoto thanks for the reply the Luniti are about the same price as Howard lifters from Summit. if you had to do it again which way would you go? Thanks for all your great input into this forum

 

Having had no experience with the Howards lifters, I'd go with the Lunati's...273/360 Retro Rollers...

 

345 DeSoto Does this cam have the cast drive gear that Ron in the Shop speaks of in post 132 so you can run a cast distributer gear or are you running a brass gear?
Thanks Kirk
