OMC 7.5 Exhaust Manifolds Needed

[newport dave]

If anybody has any idea where to locate a set of OEM or aftermarket exhaust manifolds for a OMC 7.5 (Ford 460), I would be interested in buying them.

I have tried the "adapters" that are supposed to adapt the Ford heads to be able to use big block Chevy exhaust manifolds, but have have developed problems with exhaust leaks and burned plug wires.

Thanks,
Dave

Thanks for your response Boatin Bob. I had checked with them. Standard response "Sorry, they are on national back order".

Dave,
Be carefull if you are going to try Ebay for used manifolds. I had problems both times I tried to by used, luckly I made out OK. If you do, make sure you get a guarantee that they are good.

Thanks for the replys. I heard from a guy yesterday who used the adapters and had similar issues. Anybody else ever made the conversion from BB Ford to BB GM exhaust using the Hardin Marine adapters?
