I have a bone stock 235 in my 55.1 1/2 ton PU.
I took it to the dyno to get a baseline
(thread here) . Now I've changed to a Corvette exhaust manifold with a pair of 22" Smithy's. I'm thinking of going back to the dyno before I add the dual Carter/Webers. That way we'll have an indication of how much improvement it adds.
regards,
Leon
