What is the shortblock ? 5.3 , 6.0 or 6.2 ?Got the ball rolling for this project. Picked up a T56, and went and hung out with my buddy that had the motor. Super clean, rotating assembly is nice. He has all the small parts he’ll give to me. Gonna be fun. Still haven’t 100% decided on the top end but I’ll probably build the short block and go from there.
