Default LSX High HP

Has anyone built one yet and put some hp to it?? It's killing me to find out if the 6 bolt set up is going to solve the head gasket issue. I want to see if someone is going to put down 1300-1500 rwhp without lifting the heads.

my pistons are in transit, should have tomorrow, then off to the machine shop

any 4-6 weeks and I'll be running again. Doing a few other upgrades as well.

I picked up ETP heads with 6 bolt pattern... been about 5 weeks since I placed my order, last week they were being machined... so shouldn't be too much longer. Not that bad of a wait. 6 bolt setup will be worth it.

Making the power isn't the problem, keeping the water in the block is!

While their are limitations to everything I think the LSX is, and will continue to be the best option. I think any more improvements to gasket sealing would mean changing to a different platform.

I think even with the LSX block if you neglect to take the precautions that you have with your current set up you will continue to push water...ex re-tourqeing headstuds,turning on 2nd pump before 1/4 mile pass,or making sure there is enouigh fuel in the tank.You realize that we have had a car together that has run within a few 10th's and mph of your car and hasn't had the heads off in 3 1/2 years
