Basing my comments on my 368" Batten W2 motor Duster:
There's 300-320 CFM in a W2 head. But the flow "curve" matters.
Good intake, same here. I'd prefer a lighter piston with a low-drag ring pack. Hopefully H-beam rods.
Cam sounds a bit small on In and quite offset on Ex...what's the lift specs?
It'll want at least an 850CFM carb.
Depending on tire, 4.88-5.38 gear & proper converter (probably 5500 or so) a W2/372 should go mid/high 10s @ sea level in a 3000-3200-lb A-body.
