i have got a 65 plymouth fury with a 318 poly block in it. i want to go with a 413. ok now for my questions....do the transmissions interchange, i also heard i only needed to change the mounts to do the switch, do i have to keep the torque converter with the moter it came from, (heard this from someone also), i know i need to change the radiator, i also got a set of exact fit headers for the 65 also. any other info on this motor swap would be get.
thanks
Jim
