You are buying a new, unused Scat big block Chevy stroker 2 pc rear main crankshaft, 4.250” stroke, forged 4340 steel, std mains / rods. I have not put a mic to this crank to verify any of the dimensions but it has never been out of the box. At Summit Racing, this crank will cost you over $1100. This crank is for 6.385 or longer rods so it will internally balance.

I have the block I was going to use with this crank also for sale.

Take note: You WILL have to balance it for your application, you CANNOT use this crankshaft as-is.
