1/4 mile ET guesses
Put a MP electronic ignition with the orange box on it, drop the tire down to a 235/60-15 (26") and open up the headers. This should get you to 14.9s There is a good chance the timing chain and valve springs are shot if the motor has many miles on it. Next I would put a small cam with new springs and timing chain in it and I bet you get that car to run low 14's. This wont break the bank and will be more fun till you build that stroker. :burnout:
