Does anyone know when the Magnum 360 started being put into use?
 

I have a 1990 Ramcharger and was under the impression that it was the LA? Danyone know if that is correct or is it a Magnum? Is there a way to tell visually?

LA was replaced by the Magnum in 1993.

Do you know what the differences between the magnum and the LA are?

No. Probably could google it.

I have been reading and from what I read the entire engine is different short of the crank shaft and block. I am curious to know if anyone has put a magnum into a truck that originally had an LA motor.

It's a popular swap. Get the wiring harness & ECU. You might want to do a gas tank swap as well, as the fuel pump is probably in the tank in the Magnum. The pump WILL be different from TBI to Magnum.

Oh...ok. Very cool. Thanks!

Do some reading and all you questions will be answered.
