1983 Oldsmobile Cutlass Supreme

T-tops, Rocket 350



This car is in great shape, the body is in excellent condition. It has been painted about 10 years ago when the engine was replaced. I have the receipts for when the engine was purchased.

The previous owner installed the engine, replaced the rear end with a Grand National rear end, and installed the fuel injection from the gas tank.

Tires are BF Goodrich with American Racing wheels. Exhaust has been cut off to make it louder. There is no rust or body damage. T-Tops are in good condition.

Trunk is also very clean, no rust. Interior is original with an aftermarket radio. TH350 automatic transmission with B&M Shifter and racing tach.

The RamJet 350 engine gets about 400 HP but also gets about 20 mpg. Power steering and power brakes are in very good condition.

The Boxster S engine produces 232 kW (315 hp) at 6,700 rpm, the 3.4-litre flat-six engine with direct fuel injection (DFI) and VarioCam Plus delivers a mighty 37 kW (50 hp) and 80 Nm more than the engine in the Boxster. Maximum torque of 360 Nm is available from 4,500 to 5,800 rpm. The sprint from 0 to 100 km/h is completed in 5.1 seconds and a top speed of 279 km/h can be achieved. Nevertheless, the dynamic performance of the Boxster S can be further enhanced. With the optional Porsche Doppelkupplung (PDK), the Boxster S reaches 100 km/h in 5.0 seconds and boasts a top speed of 277 km/h. The Launch Control feature of the optional Sport Chrono Package reduces the time to accelerate from 0 to 100 km/h to just 4.8 seconds.
