5.3 vortec
Is my engine a LY5 or a LMG generation 4? I just bought a 2007 silverado ext. cab Z71 4x4 with the 5.3 but the dealer was no help in identifing the motor just selling the truck. Go figure! All I know is the block is iron with aluminum heads and they all have the AFM but the LMG has both flex fuel and AFM. So how do you tell the differance! VIN# or engine # etc. Thanks for my stupidity but I need to know. Steve Meyer at smpha8@insightbb.com
