Which motor

[gonnuts]

I would like some input from some of the sbc experts on here. I'm putting a new motor in my truck & can get a 400 from a reputable performance shop or a lightly used (so he says) 385FB 350 crate engine that he has robbed the alum. heads off & replaced with cast vortecs. The 400 is 40 over with Kieth Black hypereutectic pistons, the rotating ass. is balanced. It's just the short block as I have a set of cast vortecs to go on. I'm planning on running a Edelbrock performer intake & carb(size depends on engine). I would be into the 350 for probably 1/2 of what it would take me to finish the 400. Oh ya I'm running a 700R4.
