Sky, I'm assuming those are G-Tech times before and after the Petronix. Are you using the old coil? I've come the conclusion that it's poor traction that's causing the prob. With that set up, even with a 3.08, I believe you ought to be low 14's-high 13's with a decent 60'. (2.00-2.10). What did you say track weight for the '68 was?
