Well there is an ignition interference error. Also, now that I have it home and have driven it the below things concern me.
1. 41 degrees total timing is too much, I think the timing is way off
2. The car is cutting out at about 4500-5000 rpm now that it is in sequential mode.
3. It doesn't have near the power a 427 should have. More like a 350. Had the engine builder drive it with me and he agrees that it seems to be a timing/ignition issue. Just not sure where to start. I went through the dual/sync distributor timing procedure 3 times to asure that it was correct, guess I'll do it again.
4. The first, Snapon timing light we used was very erratic as it was too sensitive, think the dual spark box was the problem. Put a cheaper light on it and it was fine. If the dual spark can mess up the timing light, it makes sense that it would mess up the computer as well.
5. Might rewire the ignition box/coil away from the main engine harness.
Anything else? I'm really starting to get frustrated, because this motor just isn't running right.
