It's official - Ed Hutchings damaged my motor. Three cylinders are low in compression and the plugs are seeing oil. This is what happens when an incompetent tuner pushes a stock bottom end LSA with stock head bolts with 23psi, IAT2s at 190+, 12.1 AFR and 19 degrees of timing. live and learn i guess . I was considering going with the GM 376LSX B15 but heard that the forged internals are generic . Also was considering a 408 long block from Texas Speed or a Jess Bubbs 434LSX.
But decided to have my motor rebuilt with forged internals . I'll have it sleeved as well.
