Thought I would join in and find some information when needed. We have an 89 K Blazer about to receive it's 4" suspension lift and some 35's for fun. All stock, original for now. 5.7 Also have a 2000 K2500 Crew Cab. I just got this truck, we needed it to pull our Buicks. It has a body lift, 5.7, auto. We do all of our own work and enjoy the hobby. We race and restore Buick Skylarks.
