Bruce, Thank you for taking the time to post my car! To answer the ? on 1/4 mile times, I have not had it to the track with this combo. We est the HP to be somewhere between 650 and 700. It makes alot of power and with the Day 2 tire and C clip's in the 12 bolt, I'm alittle hesitant to bolt on the slicks. I have plans on installing a Moser 60 Dana Rear with 3:55s. I will then step on the 502 and see what the 1/4 times are. I am going to try and get a pic of the Z in the early 80's and scan it and I will post.
Thanks again guys for a great site!
Wayne
