I bought my 1990 Silverado about 4 years ago. Since then it has undergone a total restoration. The engine has been replaced with a carburetor 350 cubic inch engine with Eldebrock cam, lifters, and push rods. I replaced the throttle body with a dual line Holley 650 , replaced the old intake with an air gap intake and spacer. a HEI and MSD Box was installed. The stock gears were replaced with a 373 limited slip gear. The entire suspension was re-done and lowered 3 inches. Led lights beneath the dash, engine compartment and grill. New exhaust, brakes, wheels and tires….. New lights, mirrors, seats, console and floor shift.
