L-72 Dyno Test

[Chevy454]

Sorry to dig this up, but I thought I would post some of my results, in case someone ran across this thread and wondered how I did.

At the Pure Stock Drags in Michigan, I was battling a bad set of poly-locks on my rockers, but did manage a couple of 13.0's. A few weeks later, I went to Gateway for a test'n'tune, and ran 12.95@108 on a crappy 2.4x 60' time the first run out of the trailer. Haven't been to a track since.

I'm still running the set of straws (chambered exhaust) on the car, but I am hoping to get a good mandrel 2.5" system and let the 427 breath for a change. We added a rebuilt rear end (went to 4.56s) and also a rebuilt tranny/converter a couple of weeks ago, and it feels a LOT stronger. Hoping to try my luck at Norwalk on the 13th...we'll see what happens!
