1926 Morton & Brett OHV Head for 1926 Dodge engine

Recent pics, a couple weeks old





Headed to El Mirage for tech inspection this weekend, barring any unforseen problems.

 

But does it run? HAven't heard anything lately.

 

We are taking it to El Mirage for tech inspection this weekend. It's been 6 years since I ran the roadster with the Plymouth in it. I am not sure it still meets spec. We will worry about running it after that,

 

Well it has been a while since we posted. The Morton and Brett head had a crack, got sold, was taken for repair that seemed like it would never happen and Rich decided it was the final straw to a long frustrating although cool project.

He let me talk him into this

I am tired so I am going to throw up the pics and see if you can figure it out.

A new Edelbrock Chrysler Magnum head. Locations of the head holds for the 26 dodge marked with center punches.



Set up, Drill





Do it fit????......sure it do.....almost



But wait, I know what to do. Yeah, this will fix everything





Uh.......I think.............

Yeah, ok, that's good.



But wait........something is still missing..........oh, I know
















I'm not PC, I'm greasy.

 

Ah.. but your new head has a small crack as well...?

 

Still.....I think it should be, oh, I don't know..........welded??



Zoom forward



Bonus shot of the spacer before it was welded in place





It is all bumpy now. Ok, to the machine shop. Fast forward

It needed some cleaning up in the holes. But today after some machining.....









Now for the spacer on the intake side









And that is where we stand as of today!

Quite an effort. I'm sure it's a huge improvement over the M&B head.

Y'know, there's probably a market out there (a small, but devoted one...) for Lego Heads. Segmented castings that you mill to length and snap together.

Curious to find out what went on with the M&B head, I know the shop that was doing the welding on it, he turns weird and sometimes very challenging stuff around for me quickly enough (well, he does take the occasional three-week vacation) probably once or more a month average for the past five years.

 

Yes, Al Liest. I hope I spelled it right. Rich has known Al for a long time. The M&B is finished but the man who bought it is keeping it with the engine that goes with it. Not sure if he plans to make it run.

Can't wait to see and hear smoke come out of this.

 

What a great reread and update on the new head! Doug whatever happened to the $20.00 MB head that sold at Hershey a few years ago? Has Rich kept track of the hours envolved in modifing the new head? Bob

 

Good lord Kid, why would anybody keep track of such a thing?

Here is what Rich did yesterday

BTT

 

nice work, skill and knowledge

 

Pretty crafty machine work there.

 

Here is today's progress. We worked on drilling the mounting holes for the intake adapter plate.

First Rich marked off where the head bolts were in relation to the ports with red tape

Then after some discussion we marked and drilled the holes.

Rich plans on drilling and tapping the holes in the head tomorrow. We actually drilled the holes in the plate with a #7 drill so the holes in the plate can "guide" the drill for the holes in the head. Once the head is drilled the holes in the plate will be opened up so the 1/4-20 cap screws will fit.

Sorry about the pictures. I can't figure out how to edit the post on my phone. The links work though. Here they are I'm order.

Bob, it was $40 and I wish I knew where it got to.

 

The word is the the M&B head has been repaired and returned to the new owner. Not sure what his plans are for it. He has the entire motor that goes with it, meaning the original 20's era race motor. It is too bad it didn't work out on Rich's motor.

Update

Rich drilled the mount holes for the intake setup and did a slick job, as usual, mating the ports to the intake.

We set the adapter plate on the head and clamped it down. Then drilled and tapped one hole at each end of the plate so we could screw it on and drill the rest. As I said before we had drilled the plate with a #7 drill so we could us it as a guide of sorts for drilling the head.

Here are some pics

First two holes drilled and tapped



Mounting plate to drill the rest of the holes



Here is a close up of Rich's port matching. He set the plate up and milled the outside of each port at a 17deg angle so the intake transitions to the ports on the head



More detail of the plate, now fully bolted on. The fitting is the coolant inlet for the head



Lastly, a little teaser of the intake bolted on. You can see the red tape? That is a head bolt location. The intake will be cut in half to work and the section in the middle will be left long so we can have and extra mounting bolt off the head stud for strength.



Few more, money shots.....so to speak





Here is another part Rich got done. He wanted to make sure you all know that the little spacer in the center is made from material left over from when he made the headers for his V8 Packard project





That is all for now! Enjoy!

Hey, ZD;
Haven't talked to you for awhile, since the stude head deal. I see you're having more fun than allowed, like usual... .
When you n Rich drilled the new head for the Dodge 4 headbolts, did you have to sleeve the bolt holes, or did you get lucky & drill through solid stoc at each location? I looked but didn't see any evidence of that in the pics. Was wondering what he was going to do to seal the stud nut holes from the coolant pressure. Didn't see any tapers for orings, either. Did I miss it?
Marcus...

 

If you go back towards the top of the page you can see that I drilled some 1 inch 6061 bar stock 17/32 and they were welded in to the head wherever we went through the water jacket. Fear not. The head has been pressure checked and is tight. Two holes just nick the intake ports and will be sealed with thin walled tubing epoxied in to the hole.

 

The head will be dry decked and have its own coolant lines.

We had to make aluminum plugs with new head bolt holes in 6 places. The spacer has two head bolts in it. It was all welded together at one time. The adapter for the intake will have 4 more head bolts that are away from the cylinders on the dodge block. There are two holes that skimmed through the intake ports but still leave enough in our opinion to support the head bolt when tightened. Those will have sleeves epoxied in place to seal the intakes.

If I remember next week I will take some close up shots.

I still think about the stude head. I want to build the set for use but I want to finish this project with Rich. His roadster can't race a V8 unless the frame is redone due to SCTA rules. Otherwise..........

Oopps, I missed Rich's reply and said exactly what he just said. I may not have posted all the pics.

Here are some pics from when we drilled out the new head bolt locations-

Hey, Rich n ZD;
Thanks. I was looking, guess I saw some of it, but it didn't register. Thanks for pointing it out, & the extra pics. I do so love seeing this type of work. I don't have access to any of the machinery to even start something like this - wants be damned... . Hope this one flat-out hauls for you.
& while I'm asking kinda stupid Q's, since you redrilled holes, any particular reason you didn't add more, for better head gasket sealing? Just rather curious.

On another note, Rich, have you ever considered using a late model something-or-other DOHC, (Ardemia style) & incorporating Larry Widmars' combustion chamber n piston top ideas? AKA: Soft Head. Need the ports, too. I know of a place that makes them (properly licensed from Endyn) in 94mm, w/at least two different pin-heights. Not real cheap, but extremely good quality forged. (Besides going to Endyn.).
Marcus...

 

I have not seriously considered a DOHC head. This started out as getting the Morton & Brett head running. When that all fell apart I was content leaving it at that. But Zenon wanted to do this with the 318 head so here we are. At least we get to use most of the parts from the M&B short block. New pistons and pushrods should do it.

 

subbed! awesome work and love the pictures, thanks for sharing!
