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.

4.8L Crank + LS3 Block: How to Build an 8,000 rpm LS Stroker


Engine dyno video.

 

Something to think about...ppl have spin 4.8s Damn near that high

 

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.

 

PD would not be smart but GM already built that setup

Look into a copo

 

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

 

Just trying to post something that seemed pretty cool...

 

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...

 

It is cool. Way cool. I love the sound of a high-winding small block!

 

But its something to think about.

 

Couldnt have said it any better.

Thank you for sharing!
