LS Aluminum short block, AllPro LSW 12°-4 heads, Jesel valve train… 225 lb/hr injectors, Ross pistons, billet everything, (crank, rods) tool steel pushrods, and twin 76/75 turbos, pushing up to 35 lbs of boost, at 9000 rpm… we never determined the actual HP due to tire spin on the dyno… but at 27 lbs, and only 8100 rpm, we were making 2000 rwhp… So we guess at 35 lbs and close to the shift point of 9k rpm, we were somewhere close to 2400-2500… maybe more, maybe less…
Crazy part… 99 mph in first gear… shift into 5th at 220 plus… I did Standing Mile racing….

Your build was definitely one on the best 5th gens I’ve ever seen. I love watching the standing mile videos You’ve posted thru the years. The onstar video still makes me laugh! I bet it was hard letting it go but I definitely understand why you did.
