My 02' ls1 made 440 to the wheels with a G5X2 cam, ZO6 heads (unported), electric water/power steering. With a radical port job (only $1800) 490 hp at the wheels (550 at the crank) is what i was quoted by Danzio performance. Not to bad on pump gas with no power adders and 20 miles to the gallon. Best part...it can handle an ADDITIONAL 200 shot of No2
