Another Mopar Off My Bucket List - Barracuda Fastback

Hey john,I have the FAST Throttle body XFI sportsman on my Hemi. I would get rid of the phasable rotor and just run your distributor with the standard rotor.I had the phasable rotor in mine and the stupid thing kept moving. We tuned mine in without it. Also verify timing on your engine with the distributor and what the computer is showing it might be off.What is your voltage when it starts? What Fast system do you have.

It looks like you're running an MSD distributor. How did you phase it? Did you modify your shaft to align the sensor with the reluctor? When we'd had the car running before I'm not aware of any issues with the phasable rotor moving from where we set it but we only put a few hundred miles on it.

We got into the program far enough today to adjust the initial timing. The car fired up and ran but it's running pretty rough so far. We've got a major header leak on the passenger side coming off the head and it seems to be misfiring. I'm hoping we didn't damage the #1 piston yesterday. We forgot we had a piston stop in when we cranked it over. We were pretty close to top (about 9' BTDC) and the starter never bogged. I suppose a compression test is in order if the miss persists.

After charging the battery yesterday the voltage is showing around 10.4 volts (while cranking) after we'd made a number of start attempts.
