Actually, it was for the stock suspension. However, since I've installed all new TCI suspension, the torque arm should supply more grip!!

No before dyno, but it was estimated about 450ish with the stock 241 heads and same cam, since that's typical numbers for a cam only LS1. The only change in the valvetrain was the trunion upgrade in the rocker arms. The trunion upgrade really doesn't do anything for power, they just make the rockers more stable and less prone to high rpm failure.
Also keep in mind the hp/tq numbers are only what's recorded since we didn't take the engine to its 6500rpm potential. If you look at the chart with numbers, the power was still climbing rapidly. I would confidently say it would've hit 540hp, but since no numbers to prove it, I won't claim it.
