GM Performance LS3 6.2L aluminum block (PN 12621766), manufactured in 2021. 6-bolt main. Very little run time. Rolled #6 connecting rod, #8 cylinder bore could use a hone/bore. Good candidate for a stock rebuild or 416/418 stroker. Crank needs turned 0.010", pistons and rods included. Normal pushrod V8 block, no DOD/AFM or VVT. Let me know if you have any questions. Trades considered.
