Hi Ted!,
I did play with the timing,and if it were not for my lack of hi speed internet,I would post a lot more.
With both ignitions it basically had the same results with less timing,but the power fell off everywhere. I also tested the HVC coil against the Firecore with his distributor. The Firecore ran better in all but one of the tests. I think that one was a fluke,because repeating the test a few more times the Firecore consistently outperformed it.
