My friend is running an '86 Coupe with a 1997 Explorer engine. It has the stock P heads, the smaller of the 2 Trick Flow cams (221 intake/225exhaust.499 in./.510 in.112 LSA), edelbrock RPM, and 625 Demon.
We are continuing to test and tune and we think we are leaving power on the table due to timing. Right now we are running a stock replacement '85 GT distributor with vacuum advance and Duraspark box.
With vacuum disconnected, we are seeing total timing of 28 degrees, all in by 2000 rpm. This is obvserved by the light on the balancer(it has a 50 degree scale)
Questions are: Is this an acceptable way to measure total timing?
Also, I think we need more total timing and it in at a later rpm, but I'm not an expert. My friend feels that the stock distributor is not curvable.
We are running a stock C6 with a tighhhttt convertor for now, but we plan to step up to a 5 speed as funds permit.
Right now we are running 13.40s@105mph on street tires..the convertor is preventing very hard launches.
Thanks for any advice...
