Raced my 73 Z/28 last night
I'll post here as this is old school territory
Well it finally stopped raining on a Wednesday or Friday night so I could get some passes in at my local race track, actually there was a small rain cloud that set us back about 20 minutes for a small shower but they dried the track and again it was only a small 20 minute delay.
On Thursday my Torque Thrust D's finally arrived so I mounted up some Firestone Firehawk SZ50's (245/50/16) that my buddy gave me when he parted out his Trans Am so I was running those on all four corners.
I was running just on the motor last night as I am having an issue with my window stich on the spray so I had just the 217 RWHP at my disposal that my lil small block could muster.....
I got six passes in and here they are in order:
.642 rt
2.066 - 60 ft
5.821 - 330 ft
8.932 @ 78.96 1/8th
11.630 - 1000 ft
13.924 @ 98.06
.662 rt
2.031 - 60 ft
5.759 - 330 ft
8.863 @ 79.10 1/8th
11.558 - 1000 ft
13.857 @ 97.79
.587 rt
2.046 - 60 ft
5.760 - 330 ft
8.851 @ 79.43 1/8th
11.535 - 1000 ft
13.825 @ 98.20
.612 rt
2.037 - 60 ft
5.763 - 330 ft
8.864 @ 79.19 1/8th
11.558 - 1000 ft
13.855 @ 97.95
.636 rt
1.946 - 60 ft
5.675 - 330 ft
8.781 @ 79.08 1/8th
11.485 - 1000 ft
13.792 @ 97.50
.681 rt
2.002 60 ft
5.708 - 330 ft
8.794 @ 79.57 1/8th
11.480 - 1000 ft
13.770 @ 98.27
The car was hooking fairly well for just street tires and is obviously running consistent. I am pleased and it is pretty close to the 13.6 @ 100 that I ran on the simulated 1/4 mile runs on the mustang dyno at www.maximumperformance.biz in Portsmouth Rhode Island.
Not bad for 217 RHWP eh

Re: Raced my 73 Z/28 last night
Thanks 
I made a couple passes with the spray and had to run a by pass on the window switch as it was getting an inconsistent tach signal so I was leaving soft coming out of the hole and letting the car build some rpm before I went full throttle and ran 13.19 @ 106, 13.00 @ 107 and 13.11 @ 104 at the end of the night, the track was dead as everyone left early so those three runs were within a 15 minute period.
I'll work on getting it into the 12's the next time I go to the track
