Speed is $...
We put a 340 with a 471 lift cam in a car. This engine ran like a house on fire in the car it came out of , 69 Swinger .The car we put it in was a pig. took it to the track it went 14.98. This car wouldn't spin factory bias ply spare tires without mashing the throttle and rocking the brakes. We put 410 gears in the car still a pig.
We the pulled the trans and put a cheap GER 3500 stall converter in the car. He could sit at a stop with 275x15 tires and melt them just stabbing the throttle with 355 gears. Took the car to Island Dragway the car ran 1360's. It was a 72 Charger Rally 340 auto.
See what your car brake stalls at. Shouldn't be under 2800. If it is get a converter. You'll thank me for this advise
