Ok guys I have a gen3 5.3 and harness in the truck now. Selling my 5.3 and buying a ls3. My question is I know I can get the Lingenfelter 58 to 24x box but my question is do i dot the afm and vvt delete and put the cam sensor in the front cover? Right now the gen 3 is in the rear of the block. Is there other options to move the cam sensor like back to the rear? Also the knock sensors, will have them on the sides of the block on the 6.2 so do they make a harness to adapt them to the factory gen 3 single harness?

 

An LS3 doesn't have AFM or VVT.
