383 Exhaust

Well, there are factory 383 A-body manifolds for this setup, as the 383 was available in '67,'68 and '69 in the A-bodies. They're kind of expensive but do show up on Ebay sometimes. Then, I believe ,TTI sells under-chassis Big-Block A-Body headers, but ,again, not cheap, but good quality.

There is the possibility that the late 60's/early '70's C-Body big block driver's side manifold will fit this setup, but I have not seen it personally. Someone else on the site may have more info here.

Thats all I have....
