I beat the shit outa mine last night and still no shim/rocker arm problems w/ 8K rev limit.


Could I raise it up to 8500 without solid lifters?(got 272 step2's, RAS, crower springs&retainers) I hit full boost @ 6k and I'd like a longer powerband.


Also, smoked a 468whp ITR and a "stock" LS1 that was faster than the 468whp ITR. I love how all LSx/LTx powered cars are always stock...
