The 3500 lb Chevelle i was talking about actually had a L88 flat tappet cam and cast pistons. Last year i built a 468" pump gas motor, stock bottm end except Forged 10.2 pistons, it does have BB2 Extra heads. The cam is a .659/.668 on 110 ctrs. installed at 106*. The motor is in a 3700 lb 66 Biscyne less driver. It runs 10.50's@126 on pump gas only, with a 150 shot it ran 10.31@131, 2 weeks ago at Baton Rouge with a 250 shot it went 9.77@137 mph the week before he was driving it around town with mufflers on it, by the way the car is for sale for $18,000.00, fully certified to 8.50.
The ref. of the Chevelle was that i was running the same size tires and a ladder bar coil over setup.
