I know im not going to go 7k all the time. I have just never seen any dyno runs with duel plain manifolds yet. Wish i had some to compair. It has a 18-2000 stall converter so will get up in rpm pretty fast. I really dont want to put the duel plain on if it will fall on its face at like 4000. Am not set one way or the other yet. Looked like the single plain followed the efi manifold almost perfictly. Would like to see motor with both manifolds dyno with no other mods.
