is there any way i would be able to take the engine of a 2012 chevy silverado and put it in a 1985 chevy silverado k20 fleetside. i also would like to know how to reset the milage(possible by putting everything new)

Answer
HI KAIN,YES IT IS POSSIBLE.IT WILL FIT NO PROBLEM.. BUT YOU ARE GETTING INTO A LOT OF WORK. EVERYHING AND I MEAN EVERYTHING WOULD NEED TO COME WITH THIS NEW ENG TO PUT INTO YOUR OLDER TRUCK,,FUEL TANK WITH THE FUEL PUMP,WIRING HARNESS,FUSE BOXES,RELAYS, SENSORS, PCM ETC....LOTS OF WORK. I WOULD ADVICE YOU TO REPAIR THIS ENG OR GET THE SAME YEAR ENGINE TO PUT BACK INTO YOUR TRUCK.. ..BUT IT CAN AND HAS BEEN DONE....AS FAR AS RESETTING THE MILAGE THIS CAN BE DONE AS WELL AS LONG AS YOUR DASH IS NOT ELECTRONIC..PULL IT APART AND REMOVE THE TAPE ON THE MILAGE COUNTER AND ROLL BACK THE NUMBERS TO YOUR LIKING. GO TO THE MV DEPARTMENT AND ASK FOR A MILAGE STICKER TO CHANGE YOUR READING TO THE NEW READING AND AFIX IT TO YOUR DOOR JAM..THIS IS LEGAL ..I HOPE THIS HELPS YOU AND IF YOU NEED MORE INFO,PLEASE GET BACK TO ME..IF YOU ARE DONE WITH ME,,PLEASE RATE MY ANSWER WHEN YOU LEAVE THIS SITE...THANK YOU ,,,,TOM..
