i guarantee most of the loss in power is from the heavier rotating assembly, the Ti rod motors rev hard and make killer power, i have personal experience with the loss

I recently built an ls2 block with l92 heads. I used some lightwt forged rods and mahle pistons, stock crank. The stock crank had to be lightened quite a lot to balance. The engine revs like crazy in a heavy truck with an auto. It is amazing what a few grams off in the right places can do.

Thanks Ryne ..
How much power do you think the heavier ratating assembly took?
20-30rwhp?

I've seen 580+rwhp with similer rotating assembly I think its safe to say those car will make over 600rwhp with stock assembly right?

Nice nitrous numbers but n/a is pretty low, my friends 06 Z bone stock on pump gas did 460/430, then with catted kooks/corsa/k@n intake/ID750's/e85 stock internal did 527/490 (STD numbers)
