I scored an LS6 and I'm having it upgraded, this Fall when it goes in the current LS1 longblock will be on the market.

Specs:
2001 Pontiac Trans Am engine
Stock except for cam, valvesprings, oil pump, and timing chain.
Cam is a TR-224 112deg LSA installed by Rapid Motorsports.
Springs are Crane duals, spring dyno tested by Bruce's Speed Shop prior to installation.
Oil pump is a Thunder Racing ported LS6 piece.
Timing chain is a Katech C5R "JWIS" heavy duty chain.
Front and rear main seals were replaced w/ new GM pieces pressed in using dealer J-tools.

The heads and oil pan have never been off the engine. 2001 was the year GM upgraded rod bolt design so no need to open it up.

I don't drag race, just commuting and the occasional road course driving event. Mobil-1 synth oil only. Mileage was 31,xxx when I bought it from Contemporary Corvette, I've added just over 24,600 since then. I have Blackstone Labs oil analysis reports from 2004 and a few other years, will get one from this year prior to removal.

Just selling the basic longblock including front & rear covers, valley cover, valve covers. No oil pan, pickup, intake, accessories, sensors, wiring, balancer, etc.

I have an accurate leakdown tester and compressor in my shop, will post leakdown #s when it's out. Buyer is welcome to re-test.
