Ok ,guys I'm going to pro street my 66 Comet. I want to drive on the street some and bracket race it too. Which one will be better for a street car/bracket car? I'm not sure on the motor yet, I mave leave the 390 in it or maybe put a 385 series in it. If I leave the 390 , low 8's will be about all it'll run. But I may opt to a 385 type if I sell my Mustang and make it my footbrake car, then I'd say high 6's will be in order. Just wanting to know which would be better on the street in a 3600lb car? Thanks..
