AFR260ccc heads. We didn't build it. Engine shop in Canada built it. We supplied the camshaft and lifters. I hope whatever it is that it has a "stout" driveline.
1066 and still climbing. Gotta bump that rev limiter up a few RPM
Look for an old Motor Trend article on "Thomson Automotive exceeds 1,000hp with blown LS7." He stopped just shy of your HP totals in favor of long term reliability. If you're bumping the rev limiter up hoping to see 1,100hp, IDK.....Youre pushing/exceeding the blocks strength limits, for sure. I hope your results dont match your forum name!!!!

That thing has 6 bolt heads meaning aftermarket block. I bet it has a lot left in the tank.
A switch to e85 and more timing would yield 100+ horsepower. More boost and rpm and the sky is the limit.

You quoted me on the Thomson engine. The Thomson engine does NOT use 6 bolts heads OR an aftermarket block. It uses OEM LS9 heads on an OEM LS7 block. Unless you were talking about the OPs motor.......

Oh sorry.. yea I meant OP’s motor, but it did seem like you were indicating this gem should not be wound any harder and I think it’s just getting started 😁
