I would say 700rwhp wouldn't be a problem, Vette guys do that quite a bit.

I'd like to see some big power out of these.

You think it will spool the big s480 good on the street?

I think an LS3 is pretty close to the perfect size for an S480.

The pistons and rods are just as strong as a lq4/9. The block is a little weak but should hold about same as the rotating assembly. 800 should be no problem. One thing I have found with the 6.2's is the rings are really tight gap from the factory might want to look into that if it's a low mile engine.

Most 100K mile 5.3~6.0's are ~.022'' +. The 30K mile L92 I just tore down was .015''. I would want at least .022'' if I was going to boost it hard.

I see that's the 6.2 is 10.7.1 with 70 cc heads that's kinda high isn't it?
