Re: 300 HD heavy duty exhaust manifold

I wanted the single 2.5" exhaust. Clean and simple.

Thanks to these forums I found out enough about them to spot this one even though it looked a little different.

Re: 300 HD heavy duty exhaust manifold

Thank you.
I just wanted to get some pics on here for reference for anyone interested. I have not seen this version of them before. I have an Offenhauser C I was going to use with it, they bolt up with no issues.

Re: 300 HD heavy duty exhaust manifold

Hey guys. I just picked up what I believe to be an HD exhaust manifold. It looks different than the one in this thread, but bolts right up, 2.5" outlet and all.
Appears to be from 1965.
