OK here is the deal. 91 Mustang Coupe. Stock block. Woverine cam, .212-.222 @.50 .493-.510 lift. Edelbrock Performer heads, Cobra Upper and Lower Intakes, MAC 70mm TB, C&L 76mm Mass Air, 24# injectors, Crane FP regulator, Under drive pullies, FRPP shorty headers and off road h-pipe, MAC catback, 4:10 gears, and its an AOD with shift kit. Now for the problem. The best it has ever run is 13.6's in cold weather. I know a stall converter would do wonders, but call me crazy I think it should run much better as is with out a stall. I just need opinions on what might the the kink in my combonation. Its' driving me nuts so any help would be greatly appreciated. Thanks in advance.
