371 build W/Big Mouth heads

I'm not a fan of 4 inch arms either. I'd rather have a 4.150 bore are a 3.700ish stroke.

You seriously a fly on my wall? I'm currently in process of building a B-block 4.185" x 3.75" 413 cube, solid flat, 10.75 comp, TrickFlow 240PP heads etc.... It's gonna be a revver. J.Rob
