Crank Trigger

I wasn't going to join this but I figured I would stick in my 2 cents. I had a problem with with my engine in the begining of my race season with a high speed miss above 6500. I chased the normal things, but wound up with a cam profile issue that caused destabilization in the valvetrain above the rpm stated above rpm. After a cam change my problem was solved. 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.
