The problem with the LS engines is that they have a long geared transmission and a low redline. The heads dont flow much past 350whp, ive seen maybe 2 or 3 guys locally make over 400whp with stock heads. a stock GSR head can handle 600whp no problem.

The LS wont make as much power all things being equal.

But, the LS is cheaper, has a longer stroke so generally more TQ compared to the GSR.

if your goals are 250whp an under, its fine
ahh.. thanks that clears alot up!! +1 -- i just have always heard from people that LS is better because of lower compression
