Fing new guy
Hey guys, just recently picked up an 03 trailblazer with the 4.3l LS 4dr. I want to do some upgrades because i know the power is there with that motor but just dont know the best route to unlock it. Help me out?

Is this a 4.3L V6, or a 4.2L inline 6? What is the 8th character of the VIN?
