Grow up. You may have had an ecotec over 500hp. Have you torture tested it? How much does it see full load? If *I* were to jump in it, would you have full confidence that it would be reliable and stand up to repeated WOT runs? (basically, my goal would be to have it **** out a sleeve).
If you have a daily driver that only sees full load about 5% of the time, you may only brush the limits of the stock sleeves briefly....again, this is simply gambling and one day you will roll on the throttle and pop an engine. YOu put any track time on that car and actually run the car, you will quickly see where the flaws are. You build it right and it will just ask for more.

By the way, compression is still within stock spec, not close to the lower end of it either ;-)
GM did good on this motor. I can't wait to find the limits of the LNF either, although to be honest I never found the limits of the LSJ.
You sound like one of those guys who gets pissy about an EVO9 on a stock turbo running 500awhp and 127mph trap speeds without nitrous. Just because you can't do it, doesn't mean someone else doesn't know how.
The LSJ will rip uncoiled 7/16" ARP studs out of the block before the iron sleeves go.

280-300whp from the LSJ is all I want. Cant do much with 500 HP through a glass tranny anyways. I am not going to argue with you and reference published facts and advice from GM racing any more. Have fun re-inventing the wheel.

eh as much as I hate this. These motors do hold up well when properly tuned actually, key is richen it up, up top. to like 10.8 above 6200 rpm to keep it cooled down (cylinder temp wise) I dunno I beat the ever living **** out of my car every time I get in it (everyone that knows me can attest to that) and I've been pushing over 350 and over 400whp for almost 15k miles without really a hickup. Still on the high side of compression tests too (somehow)
