Default Stock cube LS3 Build

I posted this in the carb section but thought some of you in here would like to see.

Wanted to share my latest build with you guys. I have a plethora of **** laying around and I had enough stuff to put together an LS3. Stock block, crank, and cylinder head castings with a used set of h-beam rods. Really the only thing new that I bought for this was a camshaft, pistons, and rings. Most everything else I had laying around. Did a few tricks with the short block to free up some power, and worked on the heads a good bit. Cut down and regrooved some titanium valves for the heads and put 7/16 stud mount rockers in them. Worked on the super victor a good bit to get it right. I put a vacuum pump on it but ended up having to run the engine without it hooked up. My goal was 750hp at 8000rpm. Finally got it buttoned up and on the dyno today. Here are the results




8200 rpm pull

Pretty nice results. What rockers did you use for the 7/16" stud on an LS3?

No kidding, so that's the steel body rockers? I thought they were for a 3/8" stud.
