Is there any benefit to using a 2 1/2 exhaust manifold on a 66 L79? Obviously, the drawback is that it's incorrect for that year if being judged. Maybe a better question would be: do you lose any performance with the 2 inch manifold when compared with the 2 1/2 inch? I'm replacing a badly rusted set of manifolds, so I could use whatever I want. The car is not being judged and it has incorrect side exhaust as it is (which I really like, so I'm not switching back) and that needs replacing as well. Any thoughts on that? Was the 65 L79 a "hotter" engine with the 2 1/2 inch exhaust all the way out? I wonder why Chevy bothered switching? The pipes expand to 2 1/2 inches anyway, what was the point?
