Big Block exhaust manifolds
 

Question for today...Will early 70’s Corvette big block exhaust manifolds fit in a ‘71 C-20 with a 402 BB with 400 Turbo? I’m thinking about putting on cast manifolds, I’ve had headers on for about 12 years and I’m starting to get too many gasket leaks. I’ve had them off, cleaned, checked for straightness, still getting gasket leaks. Sanderson makes a cool looking cast header but too pricey. Right side Vette manifold should be no problem but wondering about the left side.

If you have nice C2 or C3 BB Corvette manifolds they are worth a good bit of $$. I would think you could trade them for the correct truck ones and some extra.

I was just going to use a replacement Corvette manifold like those at Summit, priced around $120 each.
