Do you have a build thread?

I made 475/473 with a bolt on ls3. It doesn’t take heads and cam to make that kind of power. Good thing about doing a serious bolt on set up is when you decide to pull the trigger you have all the supporting mods in place. My 2015 1LE went 11.5@120 at 3900 pounds race weight.

They sell oversize pistons for 6.0L cast iron truck blocks, on which the LQ4 and LQ9 are based. They share the same displacement specs as the LS2, but the iron blocks have much thicker walls.

These pistons could certainly be used for an LQ4/LQ9. But if they can’t be used in an LS2, then why will a GM dealership actually tell you they are available for the LS2? It seems like, if they couldn’t be safely used, they wouldn’t be considered an option by the dealership.

They can be used if you re-sleeve the bore; otherwise, no.

I should be picking up my engine from the machine shop soon. I'd like to have the bearings on hand when I take it to the builder. I've read that oem bearings seem to last longer than some of the aftermarket bearings. Which bearings should I run on a stock crank with forged rods?

Engine is finished and ready to go, my builder pre lubed the engine with Eddie Gibbs break in oil. He told me to let the engine warm up to operating temp and then to shut it off and change the oil. And then to run regular oil after that to break the engine in.
