If one wanted a solid street pounder, I'd bore the thing over a full .090 over bore, which gets you to a 4.0 bore, stuff a 4 inch, 360 stroker crank with some light weight forged pistons, a custom cut cam shaft. Then max port the heads and find a way to free up the exhaust flow while making it fit in the engine bay. Stuff it with an aftermarket, runner-tuneable LS7 intake, keep the EFI and set the engine up with a standalone ECM. You're looking at 3500-4000 in parts and machining, but it'd push 500 HP easily.
