You need to ensure the truck crank does not have a thicker rear flange than the LS1 did. Certain truck cranks did and that would be problematic!

casting number 216 was the shorter crank (LS1 length) and 215 was the longer truck style.

the only difference between a 216 truck (5.3, 6.0) and the 216 (LS1) is the LS1 crank has been gun drilled. other than that, they are identical.
