Good afternoon. Question for someone who may have dealt with exhaust manifold choice. I have a 67 ChevyII with 355 engine and Turbo 350 trans which will soon be swapped for 700R4. Currently have hooker headers but thinking of swapping out for 2.5" rams horn exhaust. Has anyone used the 2.5" and if so which pn should I look for. Thanks Bob

i've heard of only one guy who ran them and heard he had to do a bit of grinding on the flanges if i'm not mistaken. plus the pipes had to make an extremely tight bend also. the factory ChevyII manifolds are a swept back style but they're not 2-1/2"

in all honesty i think you'd be much better off performance and fit wise sticking with the headers.

i hope i helped and Welcome to Team Nova ;)
