1981 Oldsmobile Cutlass Supreme

Vehicle Description

Here we have probably the nicest Oldsmobile G-Bodies I have ever had the pleasure of owning. This classic street machine has been in one family since new, and the resto mod was started about five years ago. Since the resto/mod, it has been garage kept 100% of the time, and has never been driven in bad weather.

As far as the exterior; the base coat / clear coat 2-stage paint is new, and is shown in a beautiful Champagne color. The exterior trim has been painted black to help offset the color, and along with the anodized grey wheels; it gives this car a real hot rod look. Just take a look at all the sheetmetal… there is no sign of rust, and all the gaps are factory straight. The frame and under body are extremely clean, and will make the new owner very proud to say “sure… go ahead and look under there”. To help prevent the typical “G-Body shuffle” as it goes down the road; all body bushings, steering, suspension, and brakes have been replaced within the last 250 miles. All the suspension and steering parts are SC and C, so you know they’re high quality.

The tires are also like new, and have about 1000 miles on them. The driveline in this beast is a transplant from a 2000 Camaro, and was completely rebuilt and upgraded before installation.

The LS1 motor has been forged with LS6 top end, and the 4L60E trans has all upgrades available installed to handle the extra power. But wait… there’s more! A completely new, 8 rib, D1SC Procharger kit with inter cooler has also been installed to REALLY help this Olds scream down the blacktop! The motor was professionally built and tuned by RPM motor sports, and has shown 500 rwhp on a chassis dyno.

The interior is mostly original with the exception of Chocolate Suede inserts professionally installed to help set off the interior color. Also added is a custom instrument panel, new steering wheel, and new trim panels. Carpet and seats are original, but are very clean and have been reconditioned and dyed. The interior is very nice and presentable, and there are no cracks in the dash and a new headliner.

There are a few things still unfinished with the build. The A/C system is not complete. It does have a new compressor and just needs plumbing. The heat works great. I also have not installed a parking brake yet. Aside from these, everything is turn-key and ready to go. Don’t let one of the BEST G-bodies get away!

This is a well-built street machine that will turn heads as it blows past them on the strip!
