58x engine in a gmt800?

whats all needed to make this work besides changing the reluctor wheel..trying to put a 07+engine in a 2002

No need to change reluctor wheel just go to lengenfelter performance they sell a adapter box that u just plug in to crank and cam sensor to convert it.

and tap the side of the block for the knock sensors.
depending on what throttle body you're using, buy a 3 to 4 bolt spacer adaptor.
