Can it hook?
Here's a thread with a good hooking SS spring car. I think this may be about the third time out for the car and still sorting it out. Went 1.47x 60's when the track was decently prepped. I think with some more adjustments and tuning it's a low 1.4x 60 car. Probably around 530hp car is my guess.
