Sounds like a good plan. Should be very safe if the tune is spot on. FYI an LS2 intake wont work on rectangle port heads.

Sorry have standard L98 intake for it
Thought Aussie L98 was a LS2

No problem. It's more like an L76 without AFM. Headstuds and LS9 head gaskets are good insurance too.

whitto

have headstuds and mls gaskets
is 12-13 pounds or around 660-680rwhp to conservative or about the money.
dragstrip and burnouts stuff like that was registered but got of of control.police didn't like it.

I think you're in the ballpark. My combo is similar but with an S475.

I have an L92 w/ an S480 1.10 rear also. I've been 148 in the 1/4 @ 3200 lbs or so. That was on 14-15#'s of boost, 12* of timing, and straight pump gas. Oh and through an unlocked 4L80.

So it looks like your power goals are on par.
