Ok so I got my 302 back with 400 horse and dropped it in my 85. Had a problem with my new mechanical pump so I put a small Holley electric on it and eliminated that problem. Now the car will start and idle very nice at around 1000rpm. Throttle has no hesitation when idling but when I put it in gear and release the clutch to take off the car stalls. Almost as if I’m losing fuel. After stalling it is very hard to get it running again. Anyone have any wisdom to share??
