5.9 grand Cherokee limited swap to 1969 dart

Use the OEM magnum harmonic balancer and the magnum flexplate. Elongate one hole on the flexplate to fit the 904 neutral balance converter from your 318. You may have to grind the block just above the oil pan rail driverside rear for the mini starter to clear. I also had to grind the center pad engine mount on the driver side for the summit headers to clear. I used a mopar M1 dual plane and modified the stock LA V8 throttle valve linkage to work. You also need to modify the drivers side engine mount from your 318 to fit the 360, passenger side is the same as 318. Center sump oil pan needs to be used.
