Mike- Thanks for the input. I'm assuming you've got the DP version? My duster also has a 360 with a 750 DP (4778) on it, and at this time I'm not really happy with it's street manners. That said, I know very little about that motor...I think the car was set up for bracket racing in it's former life, and I haven't dug into the motor yet to see exactly what i've got. Heck, the distributor might even be locked out for all I know.
