I went up to Lebanon Valley dragway (near Albany NY) last weekend, and was joined by Ken from Everyday Performance who was doing some R&D work of his own. Ken and I met about a year ago, when he re-did my 66 Nailhead Q-Jet. The carb worked great out of the box, but Ken also helped me tweak it and taught me alot about how to tune the carb. The results were my best ET's and MPH to date. Ken was running a basically stock 81 Cutlass 307, and made some changes during the course of the day that yielded some interesting results - I hope he catches this thread and chimes in to give more detail. People who drive '81 and later CCC vehicles will find it particualrly interesting.
