The truck manifolds I have are about 1 3/4" or 1 7/8" outlet size. Not good for performance IMHO.

There is a early 60s car manifold that also center-dumps, and I think it is a 2" outlet, so that would be better.

Parts I seek: driver doorpanel, 65 Sport Fury, prefer black, needs to be 7-8 on 10 scale, might buy set 16" x 6" Dodge truck wheel(s), from early 70s?, takes 9" dogdish - need for a research job so cheaper is better. 69-73 C-body caliper brackets and/or splashields Send a PM.
