Decided to bring the Z28 down to see what it would run. Ended up bumping into a group of LS1 f-body guys/girls from the area.
Never had the car down the track prior to tonight, predicted 13.9 @ 99-100 MPH. Ended up having a best pass of 13.76 @ 100.14. Turned a 2.084 60'. As it got colder out the car had more trouble getting off the line and started turning consistent 13.8-13.9 passes. Ended the night after two 14 flat passes.
Turned 120,000 miles on a 13.8 pass. Mid length headers, no cat, magnaflow exhaust, moroso CAI, 4.56's or 4.10s and dry rotted 275 40 17 radials, full weight 4L60E.. Overall pleased with the outcome. I think on MT drag radials I can see 13.5 on a good pass.
Edit:
I wasn't sleeping at the light either. I was trying to figure out the best RPM to launch at (900 ended up being the best spot I'd hook... 1,100 blew 2.3 60' times)
