1985 Chevrolet Blazer Additional Info:

This is a 1985 Blazer with a freshly rebuild engine with almost no miles on it. The body has 80,000 this vehicle is meant for off road. Or could be restored fairly easily meaning how the engine is already done. It has 35in tires. Just bought and installed a new stereo and speakers. It runs drives and stops but it does have a small problem it backfires for some reason when you gun it. I know it has to be a easy fix because the engine is so new but i don't have the time or know how to mess with it as of right now. It also has a dent in the passenger side door that can be popped out. It also comes with two axles that are 3.77 because the guy i bought it from was unsure if the axlesunder it where the same ratio so i decided just to buy i pair to roll under it.
