    Edelbrock Performer intake sitting beneath an M4ME Quadrajet. Would there be any differences between the base gasket that has the four individual holes as opossed to type that is completely open for a performance difference. An open or notched plenum is supposed to favor more top end but is a 1/4" gasket going to make any difference one way or the other.

    355, Federal Mogul 345np flat-tops, 210/218 duration .447/.462 lift 111 LSA, Stock L31 Vortecs, Edelbrock Performer intake, M4ME Q-Jet.

    The four hole plate will help fuel atomization better; I heard; and if you get one that one inch thick, it will help your low end torque. You also might want to check out the "Substack" by K&N, in the summit catalog.

    I had the thin one with 4 individual holes and it leaked. I went to the thicker open one and it worked great.
