hello I would like to know what parts are need to swap in a ls2 in a 2003 5.3l sierra. I know that the lq9 is easier then the ls2, but I'm leaning more on the ls2 I found one locally here in puerto rico for $1,900 with 6,xxx miles out of a trailblazer ss my goal for the truck is for 12s in the 1/4 on motor so I was thinking the ls2 tune long tube headers some bolt ons, some traction, some info would be appreciate tanks!

 

This will convert the 58x crank and 4x cam sensor to signals that can be used in your 24x/1x truck.

This solves the crank/cam relcuctor issues.

Others will chime in.
