70 Challenger 440, 30 over, balanced, 509 DC cam, 3 angle valve job,Big tube headers, stock Six pack, orange box ignition, 4 speed, 4:10 Dana...... I've never run this car on an actual drag strip so I don't know how fast it is, but will this fall and I am hoping for high 12 low 13........ I can't stand the look of the headers so I am thinking of going with stock exhaust manifolds and through the mufflers , what do you think am I realalistic in hoping for a high 12- low 13?
