Does anyone know the proper dwell angle for the FI Trigger points in the distributor? In other words, through how many degrees of rotation of the distributor shaft should the point be in contact?

My assumption is that the when the points are closed the injectors are injecting, so as the cam blocks wear on these, increasing the dwell angle, it would tend to make things richer. Or maybe they just cause the control box to send a single pulse, regardless of how long they're closed, and the dwell angle is unimportant as long as the points are functioning.

Please enlighten me.

(I've had this car since 2001. The PO had it blueprinted and put a performance cam in it to go with a big bore kit. Car runs spectacularly, has for 40+K, but I had a devil of a time in the beginning. The only way i could get it to run manageably was to substitute a 140 control box, but I still have richness problems and a slight hesitation transitioning from idle. I've tried to get the head off to change the cam, but the head bolts are really frozen in place (half inch breaker bar and six-foot pipe frozen), and I really don't want to snap several of them off in the block. Besides, it runs so well when it's run hard. Problem is, I prefer not to drive that way most of the time.)
