Would I be limiting myself if I used Vette or truck manifolds to do twin TC76's on a 403 LS stroker? Max boost will be 20psi. Engine details in my sig. If I do headers, what size primaries should be used?

Thanks. I'm not a class racer. I just do test and tunes.

I just found a GTO that used truck manifolds upside down and backwards. Keeping the AC also. Radiator leaned back a bit to fit a pipe over it. I'm going to try and do it that way.

The truck manifolds have produced 2000HP with a 106mm turbo.

I found some truck manifolds with heat shields for $121 shipped, so those are on the way.

I may pick some up from you guys. My fabricator may try and do a GTO truck manifold kit.
