i got an intake manifold from a guy on ebay for a 351m/400 the intake says sp2p-400 but the ports on it are tall but are not very wide, in fact they're only like half the width of the ports on the heads.
sp2p is /was made by Edelbrock. The risers are narrow to give the charge velocity. It is a mileage maniford and gives you more low end. I have one on my truck, and I like it
Originally posted by dustinleavitt2000 my engine is going to be like 350 hp will this manifold be ok?
Well, Dustin..I don't know what to tell you there. I put mine on to get better gas mileage, that plus a 4bbl and a CompCam 252H unlocked the 400" engine and the truck became fun to drive. Like I said..I was going for low end. Since you've got it, go ahead and try it. I gained about 2mpg, but that's cuz I couldn't keep my foot out of it.
