Huh? Forged parts guarantee a good tune, what are you talking about? I think you could push 15-16lbs on a forged 370 with meth and probably hit 700whp, and I dont consider that to be a radical. My point was that as long as you have a good tuner, your setup will be reliable. 370*2=740

Exactly what I said, I fail to see the confusion. If it nipped a piston at 10psi with the current tune throwing pistons and rods at it will not fix the problem.

You just said with meth on yours, and 700rwhp is close to 780 flywheel hp, so pretty close to 2.1hp per cube. Not out of bounds, but try to get 150 passes in at the track over a few seasons and you might get a not so good fill up on 93oct. Also a heavy vehicle such as a truck is different then a 3500lb car when it comes to tuning.

I am only stating that it had too much timing, or not enough fuel or both. Maybe it has a bad injector or fuel pump?

Well I tore the motor apart and found that piston broke the ring land and come to find out where I bought the motor from he said the motor had like 26000 miles on it and come to find out it had more like 92000 mile on it. So I'm working on that ordeal right now but I can't find my receipt from the purchase, So time to order some new pistons and get it back together.

Sorry about the engine man, take your time and build it back up right so you wont have to worry about it.. and when it gets back running, get a good tune and check the fuel side of your rig.. Make sure its not lean under operation. Just my $0.02

Yea thanks as for the fuel it is running on the rich side which is good last time I saw the A/F it was 10.8 wot but I will be taking my time and doning it right so it will last on 10lbs of boost
