Mystery Aluminum Exhaust Manifolds Can Anyone ID?
 

I picked these strange ALUMINUM exhaust manifolds up at a swapmeet this weekend. They are very interesting. I am not sure how they would survive without cracking, warping, etc. but have been used before. Can anyone help with possible identification? The ports are spaced too far apart for big block Chevy. Possibly Boss 302/351C but the ports still look too far apart. Maybe Diesel or something? They are really cool, I just have no idea what they fit.


Thanks,

Jason

How about a boat? They tend to use these over the regular ones due to the salt in the water/air

Just a thought. [img]<<GRAEMLIN_URL>>/dunno.gif[/img]

Definitely a marine application.

I'm thinking Ford also. Take one into an auto parts store and try out some exhaust manifold gaskets.

I thought boat too but these are not water cooled.

The only aluminum exhaust manifold application I can think of for a car is early Pontiac Super Duty [img]<<GRAEMLIN_URL>>/dunno.gif[/img]

Looks similiar to 351 Cleveland mounting pattern and spacing, however, the lower leg is spaced too close to the exhaust port. Ford did mark all of their experimental and production pieces with part numbers. I have never seen any Ford experimental parts without a part number on them.

That log style manifold was only used in 1964-1967 Mustang non HIPO engines. I don't think they would fit anything else.
