Slant Six Forum :: aluminum slant six head from 1959?

While I am interested in this project, there is no way I would spend $10K. I want a better head as much as the next high performance gear head, but I can't see that. Is it 10K across all that have interest or 10K each? And then we have to purchase the head? Maybe I am not reading this right.

These motors have the same bore spacing as a slant six. You could model after this antique head - at least its a hemi, relocate the head stud locations to match the slant six. They aren't a bad design considering how old it is, the valves are large for the 3.43 inch bore (4.17 stroke). I believe the most the 3.8 produced was 265 hp, but that was likely optimistic. Even an exact copy of the OEM slant six head would be spendy, and it wouldn't be a hemi. The workmanship on these castings isn't the best.

I don't know if a one-off could be made by relocating the head stud locations. Its been awhile since I saw one of these at a pick-n-pull. I laid a slant six head gasket over the Jaguar block and the bores matched, but the stud locations were different - I believe the Jaguar bolt pattern was narrower. I think the slant six bolt pattern would just about touch the valve cover gasket flange, but it might be doable. If the Jag head could have new holes bored and a tube pressed in and welded, maybe it could bolt to a slant six block. Or a new boss for the head studs could be welded in - its alloy. The head studs are under the valley rather than under the valve covers.

At 13:30 you can see the big valves

Just for fun, I contacted Edelbrock to ask if they just might be working up an aluminum head for the Slant Six. I warned them that if they weren't, I might just have to buy from one of their competitors - that usually gets the trick done.

Their reply, "At this time we have no plans to start producing cylinder heads for the Mopar Slant Six."

I'm thinking this is an intentionally misleading statement, since we all know the Slant Six uses only ONE head, not plural....

3D printing and CNC machined chunks of aluminum are the future of this hobby.

I am a no unless I can throw in $10. I will go as fast as I can (12's on a iron head). I think this is a neat thing for some but it is just not for me. Hope it works out for you guys! PS. I lost 20# when I retired and went to work for Ryan. Another year and another 20# and I'll be just about where I should be, and it didn't cost a dime!

My thinking was the money would be best spent/invested in getting a tried and true established manufacturer to do the project with guidance from the investors., ie seed money. If no one is willing to compromise on the design goals, nothing has a chance of happening. I also thought, "if you build it, they will buy it, if you don't build it, nobody will ever buy it." I don't see why it would not be at least a break even investment, with even the chance or earning a return. The head in this thread, is a very old design, with some obvious issues, hidden ones are yet to be discovered, and offers no upsides other then weight, and bragging rights IMO. I consider the weight savings a big plus, over the front axle, and at the top of the motor, on cars that tend to be light in the first place. I'd seriously consider this venture.

Well, based on the of amount of perceived interest, guess I'm rolling over my CD's.

The '59 head has been sold; it's off to a very good home. Thank you. If someone with with the time, skills, and means wants to spearhead the development of a new head - something with a nice thick deck, updated combustion chambers, decent as-cast ports, big valves, etc - I would invest. I understand what it take$, and I would be a part of it. Shooting for the moon, i.e. cross-flow, hemi, etc - seems silly at this point. I see the project as a bolt-on deal that needs to be within reachable means of the enthusiast. If you're serious and qualified, connect with me via PM. Dart270, I sent you a message. Thanks..

Edelbrock is the ideal company to do this. They have everything it takes. Except perhaps the inclination.
