no N20 on my car 93 pump gas only. at that time i was running a 9.5 dynamic 4200 stall converter. which was the wrong one for my solid roller cam. i have sense then installed a 5200 8 inch ati but have not had the money to go back to the track. hope to get it down into the 10.20 soon. also once my car is done i will be taking the engine trans etc out of the dart and moving everything over to my 73 duster.here are a few pics. thanks Mopar65
