Chevrolet Repair: Engine Replacement

Question
I have a 2006 Chevy Silverado 2500 6.0L. My engine has locked up and the mechanic said I need a new motor. My question is how do I know which engines will work in my truck? Will any 6.0 L chevy engine with the matching VIN letter work? I found a 2000 chevy 6.0L engine with a matching vin for a good price and was hoping it would work in my truck.

Answer
HI DANIEL,,THE BEST ADVISE I CAN GIVE YOU WITH THIS IS, I WOULD GET THE SAME YEAR [OR THERE ABOUTS] OUT OF A TRUCK WITH A 6.0 LIT THIS WAY YOU KNOW EVERYTHING WILL BE THE SAME...FROM 2000 TO 20006 THERE HAVE BEEN A ALOT OF CHANGES TO THE HEADS AND ETC..SURE THE BLOCK WILL FIT NO PROBLEM, BUT WHEN YOU START CHANGING OVER SENSORS AND SWITCHES YOU HAVE A 50-50 SHOT THAT THEY WILL FIT INTO THE USED MOTOR. IF THEY DONT, NOW YOU GOT A BIG MESS OF CAN OF WORMS TO CLEAN UP...YOU COULD TRY CALLING YOUR LOCAL SALVAGE YARD UP AND THEY CAN TELL YOU WHAT YEARS WILL INTERCHANGE..THEY WILL HAVE ALL OF THEIS INFO ON THERE COMPUTER SYSTEMS...MOST OF THE TIME THEY ARE CORRECT..BUT IF IT WERE ME,, I WOULD GET AROUND THE SAME YEAR AS POSSIBLE TO MAKE THINGS EASY FOR YOU.....GOOD LUCK TO YOU,,,TOM
