I ended up with a supposed 540 bbc with Jesel Belt drive, jesel rockers, and Dart 345 heads. The engine ran a 8.25 in a 2500 lb chassised Beretta. The block is a tall deck, it has what looks like GM numbers, and says truck on the back. If its a 540 it should be a 4.50 bore.
I guess what I'm trying to decide is should I move everything into a Dart or Merlan block before I run the engine. Or is this truck block ok.
