Cam Shafts

The factory had slightly hotter cams for four speeds since their was no torque convertor to affect idle/driveability but there is no desiganted cams for one or the other in the aftermarket and the factory four speed ones are fine with a stall.There could be a bunch of things going on with his car such as timing,carb issues and low compression,the first two can help mask that with proper tuning.Im also guessing he doesnt have a true 2400 stall because thats alot of drag on the engine when put it gear,if his stall was that loose he would only drop a couple hundred but not seven,the convertor is a bit tight.
