833+magnum?

If I understand correctly, he took the crank pulley and machined 8 slots in it and mounted a sensor to duplicate the flywheel signals the computer needs. Probably the best plan if you want to use the EFI with an A833 trans. Be cool to see some pictures. BTW, as I recall the first slot is 8 or 10 degrees ATDC, but don't quote me.

Running a 4 speed with EFI has provent to be very difficult. The only flywheel Mopar made with the notches for the sensor is an 143t flywheel and won't fit the car bellhousings. I know of one guy on here that had one machined down for an 130t ring gear, and he planned to do more and sell them but he dropped off the planet so I don't think he was able to get it done. I know someone else has tried to do the same thing and all the shops he talked to said they either couldn't or wouldn't. Another guy on here had a custom one machined, and I ran across one other person on a different forum that had a custom flywheel built, but pretty sure they were $400-500.

And you need more than a notch in the bell to clear the sensor, you need notches in the flywheel.
