I have a 2001 4.3L (factory) in my 2001 Blazer, is there anyway that I could possibly swap an older engine in and have the computer "say" that it is newer than it is? Or, is it as simple as just using a 2001+ computer on an older powerplant? My home state does OBD checks. Make sense to anyone? It is much easier to relay verbally than typing... This is my goal, LT-1 Supercharged, runs 10's!
