I am a newbie on this forum but have been tinkering around with my 87 GN for about 6 years now. I have been a technician at a private shop in cincinnati for about 5 years now. I know a lot about service but not so much about the performance field. About a month ago One of my buddies and I were out laying some patches and i lost the #1 rod bearing. Pulled the motor and trans and tour it down to the bare block. Every bearing in this thing was wiped out. None of the main bearings spun just the #1 rod bearing. It is basically welded to the crank. I gave up trying to get it off. I have recently purchased a new rotating assembly from Full throttle. CAT crank. Girdle, K1 rods, diamond pistons .030 over, diamond rings, and king bearings. Am i on the right track? Have you heard any good or bad things about these assemblies? I would also like some help with the heads. Plan to stay with stockers but would like to rebuild. I would like the car to reach mid to low 11's. Any suggestions for springs, valves etc... Thanks alot guys. I am a little long winded but i love this car. Thanks again.
