Re: My 1/4 Time?

Depending on how good a tune I'd roughly say anywhere between a 15.6-17.

Re: My 1/4 Time?

I ran a best of 15.597 @ 87.33mph in the quarter. My car is all stock, besides some free mods and exhaust. It's the same year as yours and I have the same engine, trans and gears as you do as well. So you should be running very similar times. But if you really want to know what your car will run, take it to the drag strip.

BTW my car ran mid to high 16's on 7 cylinders so 17's seem a bit far fetched.
