What made A bodies non-popular

and about it being an auto, it is a drag car and i was told that if you have a 4spd when youre drag racing you dont take your foot off the gas even while shifting so its like put clutch in pull shifter pop clutch and the gas pedal never leaves the floor. cause if you take your foot off the gas and you clutch and shift as fast as you can you lost like 2 tenths of a second. so for driving around and occasionaly stop light running or interstate racing a 4spd is great but if youre running your car stricly on the drag strip an auto is best. now i dont drag race on the strip i mostly drive around and stop light race or play around on the interstate so i prefer a 4spd.
