I think I might have lifted a head when I was spraying a couple weeks ago but the problem hasn't reared itself again. It might have just been a bad coolant tank cap with the extra pressure from running it at high rpms for a while. But, I am thinking that the 19* of timing on the 135 shot was too much cylinder pressure for the studs HAHA. Man, does it run good though.
I am selling the stuff to start my turbo build. I figure if I want to keep this motor around a while I had better lay off the nitrous. The turbos will make as much power as the stock blower on nitrous with less stress on the motor.
