thats not bad at all. you should be running the 1/4 much faster than 15.5. you probably just need to do a good tune-up on it.

Check EVERYTHING in the ignition system. Set of wires can't hurt.
Use 600CFM Holley vac secondary ( thats about what they came with) Get it working real good.
What gear/tire are U using? You could have .70 in ET just with gear/tire.......

Being the first 1/4 in this car for me, I was definitely improving. Plus, I hadnt done a tree like the one at Seattle Pacific Raceways in over 6 six years. The one at the 1/8th miles is slightly different. But my R/T was improving, and the stang didnt hop at all on this surface. At the eighths it hops like a mad man. I was trying to carry the gears as far as I could.

As for the tires, they are:
Rear - "Federal" 225/60R15
Front - "Grand Spirit - Aqua Flow" 22560R15

The rear end is a 7.5, with ????? Gears. Probably stock. Is there an easy way to tell the gear ratio by visual inspection of the gears? I would like to take the diff off soon, just for check up anyways.

Tranny is a T-5 with 3rd and 4th gear issues. It definitely grinds in these two. However, I never got to shift to 4th in any of my runs, but I was very close to the end of my 3rd range at the end.

One guy at the track was thinking of selling his upper/lower control arms, which is probably the next investment for me. Its that or a T-5 Rebuild, but I'm nervous to do this on my own.

remember being consistant is more important

Valcore

that time is not bad at all... I mean think about it, 1983 mustang GT stock has
175 HP @ 4200 RPM
245 ft/lb @ 2400 RPM

I would be pretty happy, do you have any pics of your car? i really like the early foxes especially if they are in good condition.
