Building my 440SP motor with stock pistons and that 290@.050 solid wasn't the ticket, running the 14x32's @4.5psi was no good just because everyone else ran them at that back then, and the 90/10's weren't the best, probably would've done better with some used stock shocks, too much front end rise, apart from that the car still ran well and managed 10.7's with 2.14 906's but I'm sure I could've gone quite a bit quicker today with the same set up just changing those things, at the end of the day my goal was a 9 sec pass which I managed with a small shot of spray so not a bad way to bow out of the sport in 1990.
