The car weighed 3560# with him in it, so consideing the difference in weight and aerodynamics you're pretty close I'd think. You will definitely be able to tweak a little more out of it if your track has test and tune in the cool months. That 11.96 pass was on a cool, clear March day in the 40's with the sun shining all day. It warmed the track up just enough to get warmer month 60 ft times, but the engines loved the cool air. My '82 Z28 also turned its best ever ET with the set-up I had at that time.

BTW, I looked at one of the old Log books, and we were running 38* total timing, launching at 1800 and shifting it at 6400. That produced the best ET's. We would dedicate days at T-N-T to shifting and leaving at different RPM's and it never ceases to amaze me how much hidden time you can find in a set up. Other days we'd do the same thing with timing and jet changes. We would only make small changes at time, and write it all with the timeslip info. It can be a very good tweaking tool if you are doing it.
