Thanks for all the info so far. As far as the cars usage, just street. I have no intention of breaking stuff at the dragstrip, although that would be a dream. Here's some info on the car so far. Dana 60 rear end with 3.55 posi. KB 243 pistons, .030 over. Forged crank. 4 speed. That's where I'm at so far. I'm not trying to squeeze every last tenth out of the car, just mostly wanna scare some women and children at the cruise night scene...
