Edelbrock Performer or AVS carbs for 318 dual quad?

Tune the carbs right for WOT and it'll be a screamer. You have the shorter stroke 3.31" to wind it up, then you use that cam? How high do you plan on winding this with that hydraulic roller?
On my 360 build and it's 3.58" stroke, with 4.10 gears. I haven't even considered my converter yet, my Offy is the low rise version so the plenum will be smaller and my cam is a slightly bigger SFT.
Here are the carbs I plan on using: Edelbrock 19049 Edelbrock AVS2 Series Carburetors | Summit Racing
I think you'll be fine with 2x500cfm and mechanical secondaries.

I suspect your issues will lie elsewhere... You may want to consider some STOUT valve springs.
That's what Howard's recommended when I filled out their "cam recommendation form". I spent a lot of time reading David Vizard's book and looking at cam specs, I'd have probably picked this cam but I know even less about cams than I do about carbs :) I don't know how high I can wind it and keep it reliable. The block is a 1976 LA block that will be bored .030 over and I'm probably going to run KB 399 pistons to get the compression I want and they're grooved for Total Seal gapless. If the hyper's aren't a good idea I'll run Icon domed.
