This truck is in spectacular shape for a 1987 Blazer. To start off with the all the good. the body has been off the chassis and bed liner has been sprayed under the truck as well as the inside floor front to back. The bed has custom panels inside with new speakers installed. All the seats and the dash are covered in boat grade leather. Drive train is a stock fuel injected TBI 350. its followed up by a 700R4. It has the 10 bolt axles and new 35-12. 50 15 Mickey Thompson MTZ tires. Everything under the body is under coated. I am not sure of the axle ratios but they're more than likely 3. 08. 4wd works and the truck runs and drives the trans is good and has a mild shift improvement installed. I do have a '96 vortec 350 fully dresses with the serpentine drive and accessories. extra throttle body spacer and throttle body if interest for the buy it now price. GM Performance makes a intake that makes the Vortec bolt directly in that uses the TBI . The only negative thing is it does have 141. 00 on the engine and has the cold start blue smoke from valve seals. But everything else is good to go.
