We just finished installing a 416 LS3 from Futral Motorsports this past week. Im currently breaking it in, and putting some miles on it. We are strapping it to the dyno July 31st.

I just wanna see how close everyone will get.

416 LS3
Diamond Pistons(coated skirts)
Callies Compstar Rods and Crank
Meaux Racing Ported LS3s(354@700/Intake 240@700/Exhaust)
238/254 .646/.639 114+4
11.8:1
Rick Crawford Racing Intake Manifold/TB
Kooks 1 7/8" LTs, Kooks 3" Catted X Pipe(No mufflers on the car)
Yank 3600
Factory 6L80 Trans.

A Z06 that just left the shop has the exact same cam, same flowing heads, but obviously through a manual, and a few more cubes, made 59Xwhp.

My guess is 535/505

I think you are being optimistic. My guess is 499/ 467 on a Dynojet.

Nice! I had a 416 in one of my G8's as well and it made a little over 510/500 and was fun to drive for an NA car. I had stock heads, stock intake, and a smaller 236/243 cam though. Should really jump with the converter! I ran mine just for fun with the stock converter and was still enough to get that 4,200lb pig into the 11's on street tires.

Good numbers. Which intake and cam though are you running in the G8, the one in your signature or the one in your mods list?
