Most power on stock LS2 Block? What is the most power people have dyno'd to the wheels with the ls2 block? 364 or 402? At what point is it manditory to switch over to the Iron block?
Is 1200whp achievable on the stock ls2 with factory sleeves?
Regards,
Justin

I don't think the actual hp limit has been found yet. We are going to press it with a 94mm turbo. One of the coolest things about the LSX engines is that they are full aluminum. Why give that up if you don't have to. As you see in those threads there are some very fast high hp cars that have chosen to run aluminum and so far it seems to be holding up to anything anyone has thrown at one.
New motor should be done sometime in July. The LS2 will be torn down as soon as the new one goes in. So far there are no signs of any problems. Might be turning it up just a tad next week. 
So far it has gone just a hair under 167mph. Wouldn't mind seeing a 170 out of it.
