One of the conditions that was resolved was the timing jumping around while trying to set it. My issue is a small base circle cast cam core that was flexing with the aggressive lobe. The new cam had a different lobe and a slightly bigger base circle and cam core. I figure my cam was flexing and this was the reason for the timing variation.
I can see benifets to a crank trigger, when you are running very aggressive roller cams with alot of spring pressure causing cam flex in certain circumstances, and timing variation. With a crank trigger you eleminate a few parts that can cause an issue, nothing is more accurate than taking a signal off of the crankshaft. If you have a big enough cam core, and the right lobe design for what your trying to do, I'm sure a distributor will work well. I'm not really sure you will any ET in one over a good distributor. But I'm sure it won't slow you down. Your mileage may varry. Good luck.

now, if your distributor was at the FRONT of the engine, you wouldn't have had this problem,correct?
