Magnum 360 crankshaft same as LA 360?

Like the subject says are the Magnum 360 crankshaft same as LA 360 cranks?

I don't know if the crank is different, but the ballance weights on the converter are different?
I think they will interchange, but you may have to check the ballance?

I KNOW for a fact that the 318 La and Magnum cranks are one and the same; IDK about the 360s. but I do know that the external balance of a Mag vs an LA 360 is not the same. I had heard somewhere, the difference there is piston weight, could not tell you if thats the ONLY difference.

The Hollander Interchange shows the 360 cranks interchanging '74 to '93 and '93 is a Magnum. Same top year for the 318.

Something changed in '94 for both.

The cranks can be interchanged but the balancer cant. You will find a lot of good info in the "How to Build Big-Inch Mopar small blocks" book (#SA104). Explains the differences between the LA and Magnum engines, and building the SB stroker motors.

flexplate balance is different, too.

Dumb question....but dont the Mags have a 1-piece RMS?

NO they do not.
