Big carb (Quick Fuel 850) on a small engine?

If your not building an all out race 318 motor run a 650 or 750, lie at the car show that its an 850 or 950.
I'm not going to lie about it, I just find my self strangely obsessed with the Holley 830 annular booster model. Heck, I prefer sleepers so if I was gonna try to fool people I'd try to make it look like a 2 bbl :) But... talked to the machine shop that's going to be doing the engine for me and they don't have a 318 core so I might get stuck building a 360. It'll either get the 830 or a 4779.
