[DeTomaso] Weber manifold question

This may depend how much port work the heads have received (most have at least some porting), but in photo's my C302B's don't look too much different than an A3, flatter on the bottom of the intake like a 'D' shape, although I admit I haven't had the two side by side.

Sure is a lot of work, when there are options out there. Is Kelly still casting manifolds?

 
> One idea is to call Kinsler. They list a 3-piece manifold/throttle body for SB/Yates. It's probably pretty close to the C302B heads.


Yes, I have that mechanical Kinsler 3 piece for SB/Yates heads and a set of C302B heads, ultimately it wil be converted to EFI. My new stroker has A3 heads and I was hoping the Kinsler would port match on that, but going by your above comments I'm not so sure now.
