HEY! orange, it sure would look cool, that manifold, i was the one who said plenum volume should equal engine displacment, maybe cut it back to runner and plenum together, 12yrs. ago I could not find pissass info about intake plenums in USA had to go to England for info. you should see some of the crazy *** manifolds I have built since then. cant say how well they work tho! but had fun.

speaking about GM engines, has anyone looked at that darn ECOTEC 4cyl. GM racing got a performance manual out tells how to make them go. over a 1000hp, the manifold is twice the engine volume. maybe they dont know they cant do it so they do it anyway. gotta love innovation. OH! yeah, 7.40 at 200mph,4cyl. get out!!!
