Post your 13 sec combos
13s? I have to go with my Stock B-body. Stock 440 4-speed with stock exhaust. With short 26" 50s tire height on 3.54:1 rear gear. 13.44 at 106 MPH.
My 2014 Cadillac XTS pulls ahead of GTX in first 1/8. And holds lead thru 1/4. But after that? The 440 easily over takes the stock twin turbo XTS 6 cyl. Cadillac is done at 130 MPH. GTX is just getting mean. It has buried its 150 MPH speedo. With its taller 28" highway tire. (Where and when is of course classified.) But was very much alone and away from any population.
