Default 8,000 RPM LS3 with 4.8L crank

Pretty sick motor, sounds great! I'd like to see what they could get with EFI too. Torque curve doesn't actually look too terrible to me either.

The trouble with a traditional 4.8 is the head limitations.

Such a cool combo here. Id love to see the same with a 4.125" bore and a PD blower. If you have to get custom pistons anyway you may as well go all out.

I know about the COPO. And you don't like PD blowers. We get it.

6.0 (4.020") with a 4.8 crank, and a turbo at 20 psi, revs to 8000 rpm. Turn up the volume for this one...
