What is involved in replacing a 5.2 with a 5.9

[Bighead440]

^^This is the big difference in the older LA and the Magnums, too bad the LA's weren't done this way. Magnums are balanced with weights on the flex plate, while LA was balanced with weights on the converter. Magnum converter bolt pattern is not indexed, either.

Early 5.9L Magnums use a weighted converter and all early Magnums use an offset lug on the converter as well.
