As a point of reference, the original CSX car as tested ran a 12.2 for a car against the 427 Vette 12.8 for a magazine test
Like most here, I have a lot of heatbeats in my 65 FFR roadster and it is not a drag race car at all. It weighs 2247 lb, split 45% front and 55% rear. Using a factory stock 1995 Cobra engine, a EFI 5.0, with street tires (295/50R15 Goodyear Eagle GT II), 3.27 rear IRS, we ran a 13.087 first night trying. Traction was good after 2nd gear (1.9 sec. 60 foot), experience was lacking; maybe next time break into the 12's. Car pic, see
Blue Roadster & Mt Hood
May try drag radials combined with better techniqure for 0.4 or so if lucky.
The BB cars have so much more torque that traction is probably a bigger issue than a small block car.
