Awesome!! I feel so much better about my LY5 short block purchase now ($125). Albeit, I'll be throwing in some forged rods and pistons, it's still comforting to know that the stock foundation is pretty solid right out of the box.
The motor didn't seem to suffer much of what I've been reading on these boards eg. heads lifting, crank flexing, caps walking, etc. -or- maybe they just didn't report these issues?? I don't know..
In the mean time and in between time, I more than anxious to start working on my new "boost junkie" motor.

It's not completely stock but there are members on here making big power with stock engines. A good tune, well seasoned short block with LS9 head gaskets, and studs will take you a long ways. Too many factors to put a number a reliable # on. One guy might make 1000HP in a light well tuned car and last years, and another in a heavy car or truck with one little mistake could let go at 600...

going to add nitrous over the winter to get the huge turbo to spool, have not had any luck with the car at the track 10.31 at 147
