Up for sale is this 1986 Chevrolet Monte Carlo SS Notchback Coupe, finished in white over a burgundy interior, powered by a 400 cubic-inch V8 running through a 4-speed automatic transmission, with 94,321 miles on the clock.

This is a subtle but extensively upgraded version of the classic fourth-generation Monte Carlo, the last rear wheel drive platform for the nameplate. Between the 400 cubic-inch crate motor and the extensive refresh of the paint and running gear, the current owner did a thorough job improving on the basic goodness of the B-body chassis for a fun muscle car. Simple but extensive exterior work plus thorough performance-minded engine and chassis work make this a very desirable example of these iconic American coupes, and is ready to go for the next owner.

The exterior of this SS is in very good condition. It sports a quality refinish in the original white color, with great depth and consistent color tint across all panels. The exterior is completely stock, with the exception of the aftermarket reverse-cowl induction hood, still constructed from steel, with excellent fitment with no gaps.

The nose of the SS is very clean and free from blemishes, with fresh graphics and badging, with aftermarket upgraded headlights installed but otherwise stock. In back, all the black trim was refreshed, along with new badging installed in the proper position. The freer-flowing stainless steel exhaust twin pipes are seen extending just beyond the lower lip of the bumper.

The flanks of the SS are clean with no dings or dents, and the three-color stripe is straight and properly aligned. Wheels are the factory equipment mag style wheels, with new Copper Cobra tires.

The interior continues the factory look with subtle upgrades. Seats are the factory cloth buckets in burgundy, and are in very good condition. Side bolsters are firm and free from wear, with proper color and no rips or tears. Touch points like the armrests and steering wheel are all clean and intact, with no ripples or shiny spots.

Carpeting is thick and in good condition, with no color fade, The dash and instrument panel are in excellent condition with no cracks or warped plastic, and is almost completely factory original. The exception would be the Dakota Digital retro instrument cluster, with integrated LED screens and period-correct analog style gauges.

The upgrade list here is extensive and again illustrates the thoughtfulness of the modifications made. The SS is powered by a blueprinted 400 cubic inch crate motor, which produces 508 hp at the crank according to the seller. Equipment added includes an SFI balancer and flexplate, single plane intake, a Demon 850 cfm 4-barrel carburetor, Edelbrock water pump, HEI distributor with Davis coil, American Racing 1 3/4'” stainless-steel headers, and an aluminum radiator with dual electric fans and an Evans waterless cooler for proper running temperatures. Power is fed through a rebuilt 700R4 4-speed automatic transmission, with a 10” Trans Specialties lockup converter with a Bowler lockup controller.

The Undercarriage is clean, showing some minor surface rust in sports but no structural issues. Additional mods are visible here including the cast aluminum transmission pan and braided AN lines for the B&M Super cooler.
