Here's the deal, I had an ls setup, stock. Went boost, decided to just go ahead and build the bottom end. I stuck w/ the ls block, but obviously went w/ the gsr internals.

This leads to my question, what kind of compression "should" I be seeing w/ an ls block, w/ gsr crank, rods and wiseco 9.1.1 compression pistons w/ teh ls head?

If anyone has any insight on this, I'd appreciate the info.

 

Uh, 9.1-1

 

Actually, if the pistons are 9.1 c/r for GSR then you'll actually end up with lower than that since the LS chambers are larger. Putting the GSR crank/rods should have no effect on compression, it's piston choice that makes the difference.
