What Carb for Poly Stroker

I run the BIG TQ on my 318 winter motor. I luv it.

I wouldn't run any less than the 750DP on that small-cammed engine, unless it doesn't have much for cylinder pressure, then a 650 DP. But in both cases, only because it's on a square-bore intake.
My carb of choice would be the TQ on a spread-bore intake/no adapters; I love those carbs. But a close second would be a Q-Jet, again on a spreadbore intake/no adapters. I would pay extra for a spreadbore intake.
BTW, I'm not dissing your cam selection; at 10.8 Scr she should be a real stump-puller.
