overdue for an update.

Let see, M&H was not the issue. I had a few plug wires which ohm'd all over the place so a new set of wires was installed. The main root of the problem was a coil going out. So after fixing things, I figured I finally had the car figured out for the 2020 Pure Stock Drags. Well needless to say, there was still an issue as the car was off a full second even though she rev'd to 6K with no problems anymore. I also had some shifter linkage issues as the shifter would get stuck in 2nd and 3rd on occassion. So, back under the car for more troubleshooting. I fixed the linkage as it was off slightly. Then I found the next problem. Pypes Race Pro mufflers rusted out internally and the fiberglass clogged the outlet. There was my flow problem and missing 100hp which was costing me a full second.

Martin FAST/FS race in the fall last year (2020) she was back to 12.80s at 109/110mph. So we are finally making some progress in the right direction.

This year brought an unexpected rear end rebuild. I had to give back the loaner 4 pinion STT and GM 4.33 gears, so in went a new Eaton and Fabcraft 4.33s. I also replaced a leaking rear axle seal.

After 5 years, my hard work finally paid off. Martin FAST/FS Spring Nationals last week, right off the trailer I was rewarded with a 12.50 @ 111.36 with a 1.87 60 ft!!! I'm ecstatic!!!! I had a couple 12.60s a couple 12.62s and some 12.70s. Car was pretty consistent, lots of 1.95 and 1.96 60 ft slips. I ended up paired against a 71 GTO 455HO car and was victorious, so I'm 1 for 2 vs 71 GTO 455HO cars.
