Welcome to CHR:

Oh it would be nice to have an LS9. If you had an LS9, you could do burnouts all day long and beat the pants off most anything – but what you have is a run-of-the-mill 2-bolt 350 with a 1 piece rear main seal that was used in a gazillion cars and trucks from 1986 onward.

The LS9 is a Generation 4, 6.2L, aluminum small block engine used in Corvettes between 2009 and 2013. It had one casting number – 12621766 and to find one is a good thing! The LS9 is rated at 638 hp @ 6,300 rpm with 604 ft./lbs of torque. It was a Corvette exclusive. LS based Vortec engines were used in other cars – but the legendary LS9 was never shared among the GM family.

Such is life....
