No, I wont be doing any as-cast testing. The ONLY unported manifold I like is the Holley 300-25. The rest need work!Chad, will you be testing them all in as-cast then again after you rework them?
which, in order, flow best etc as-cast, then after reworked?
The first Holley and Edelbrock are comparable to each other but not the others and the other 4 are closer to each other..but as we know runner length alone doesn't make an intake, but helps.Sizes. Measure in middle of opening and lengths in middle of runner.
