Did you ever here it detonate? Forged pistons can take quite a bit of abuse. I've had the Cobra detonate quite a bit with the forged pistons and haven't had a problem with them in the 2 years they've been in there. I also have around 30,000-40,000 hard miles on it.

As I recall his compression is 9.5:1? I think his cam has a 111lsa but I can't remember for sure. I think he's running 15lbs.
