Justin is right that the 60' is killing you.

However, 88 mph is only going to get you a lower 15 second slip.

Sounds to me like the car could use the basic maintenance items and it will pick up 2-4 more mph, and become a high 14 second car like a stock, 350 tpi car typically was.

i dont know what vette guys run octane booster but chances are they are slowing themselves down too...
