ISO BBC performance exhaust manifolds
 

On the hunt for either stainless marine, gil, CMI, or any other decent performance manifold with risers out there for a big block chevy. 454 gen 5, bravo 1, 9.6:1 compression, 088 GM iron heads (365 horse heads) Erson marine grind cam with .585" lift on intake and exhaust. Intake duration is 226 @ .050" and exhaust is 218 @.050". Factory GM high rise with a 750 Holley. Was going to go with lightning headers but unfortunately with how my exhaust tips are mounted so they clear my swim deck, they won't fit.

There is a wanted section if your looking for parts.

Got 2 sets trs dry pipes. 2 sets wet with mufflers. 1 set wet short pipes. 1 set gil manifolds make me an offer https://cimg2.ibsrv.net/gimg/www.off...5b6c18ba46.jpg
