lsx core shift
#24
Maybe so but I have found
no evidence of true core shift. There has been a lot of finger pointing to photos of an LSX block honed out to different bore sizes per cylinder that has been represented as core shift. While you may not be able to prove exactly that a block has been core shifted without a sonic test does it matter if the block is strong and machines out correctly. Core shift is a casting problem where a block has not had the metal pored correctly during the casting process. It is either going to be weaker or not true for the bores in the block. All I am saying is the one I have has been as true as any other block I have dealt with. So all you can say is that the block may be less strong in some way. I have seen no evidence (and I have looked all over for it) that I can verify that anyone has had a real big problem with these blocks. I have heard but again not able to verify that some of them had material problems that exhibited in the machining process. I would think that some of the vendors on the board would be able to say something to this if it was a real problem.

I dont think it was a real big prb cuz before I bought Mine used I called GMPP and ran the Casting numbers threw there Engineering Dept and they acted like there was a few before they hit the market they knew about but none after the RnD stages...but Of course there prb goin to tell us what we wanna here also

Core shift is scary because of the investment made. That core-shifted boosted GMPP 454 LSX crate motor over at Camaro5.com cracked like an egg and GM said the warranty was voided because of boost. The only way I'd use the LSX block is to have it sonic tested before I buy it.
