The vacuum line that goes to the distributor is above the throttle plate on the carb. The convertor is the stock power glide that came from the factory. I would like to up grade to a 200r4 later on, but for now it would just be nice if it ran right. It I set the idle at 700 in park, it drops to about 350-400 when put in gear and stalls. If is set the idle speed in gear then in parks it is far to high to put back in gear.
