when you do the swap and useing the 05 lly and trans too do you have to chang the tcm on 02 trucks I have a bad pistonin my lb7 and found an 05 lly and trans with 70000 miles for $3500
the strarting problom started after i removed the egr and changed the y at the same time i did the exhaust and ran the overhead, started good before that with the glow plug code
Bats are new first thing i thought of injectors only have 40000 on them
Could taking the egr off and putting on a fed. Y do this there are no eve codes
