Does anybody know what kind of horsepower/torque can be expected from a stock 4.8 with all the emission deletes done, headers, and a really good tune? Is 315 at the flywheel a reasonable expectation? Thanks.

Mine is 320 at the flywheel with 243 heads, emissions deleted, dyno tuned, ported LS2 intake.
