I a stock SBC 400 engine with a Comp Cams 12-205-2 cam(.425" lift) 252H,Stock 882 heads,Edelbrock 2101 intake and Edelbrock 1406(600cfm) carb,engine runs good but I am considering a upgade to a Edelbrock Air Gap RPM intake(#7501) or a Edelbrock Performer RPM intake(#7101) and a Holley Street Avenger 670 Carb will these upgrades be OK for the stock SBC 400 in a daily driver 1978 Monte Carlo,Engine is on a engine stand right now that I paid $600 for it and don't want to spend a ton of money on this engine by it being for my daily driver?THANKS

Rpm or rpm air gap is a very popular choice for any sbc, so I think you come to a good decision on that, I would go with an edelbrock 750 for a daily driver. They have an AVS series that I don't know anything about, but have heard good things.Unless you are wanting a holley for a specific reason. IMO, edelbrocks dont require as much maintenance as Holleys, especially for a daily driver application. I ran the 750 edelbrock with an air gap intake on an almost stock 350 for almost 5 yrs and I loved it. JUST MY OPINION! Good luck!

For a stock motor, I would consider the Performer EPS manifold. It is a square bore lower rpm manifold. I have used them before on GM crate engines for engine swaps.

Edelbrock Performer RPM or the Edelbrock Proformer 2101 I have now which I don't think will mate up to the Holley Street Avenger carb?THANKS

Is there any reason you don't like the eps manifold I suggested?
