1962 Oldsmobile Starfire

This is a rare 1962 Oldsmobile Starfire with a ProStreet LS376/480 Engine with 4L70E Automatic Transmission installed by Southern Performance Systems. A lot was done to this car. Obviously the engine and transmission were upgraded but we also beefed up the rear end, updated the fuel delivery system for EFI with a custom built fuel tank, upgraded the brakes to Wilwood brakes, and improved the steering with new Flaming River column and hydroboost system. Improved the suspension with RideTech control arms and AFCO coil-over shocks. The interior was renewed by our friends at Fountain’s Upholster. This car rides and drives like a modern car with that classic look. Updates to the interior include Vintage Air AC system, Dakota Digital gauges, American Autowire body harness, and a Custom Sounds radio with that classic look.

The GM Performance Line offers the 480 & 525 Horse Power LS3s plus the LSx 376 and the LSx 454. Horse power options for the factory and performance LS engines range from 300 to 665. SPS offers custom builds using aluminum block and the more serious LSx block. For the budget-minded, there are some good used take-out engine available at great prices.

Transmission options include 4L60E- 4L70E-4L80E-4L85E and the new 6L80E & 6L90E 6-speed automatic transmissions. Manual transmissions such as the T56 Magnum and TKO600 are also available. SPS provides transmission that use a standard slip yoke, where as the production units use a fixed yoke that requires a 2- piece driveshaft. The 6-speed automatic can be used with a paddle shifter for those who want to shift the transmission without the use of a clutch. For high-horsepower engines, custom transmissions can be built to handle to extreme power and torque. Our stock torque converters work great with most engines and we have high-stall converters for our big cam engines. When setup correctly, these high-stall converters provide great gas mileage and work just fine on the highways. SPS will pair your engine and transmission with the converter that will work best for you.

All engine management harnesses are custom made to fit each engine/transmission package. Along with the harnesses that we offer, SPS also offers GM Factory ECMs (Engine Control Modules) and TCMs (Transmission Control Module) and custom programming. Each harness comes with Check Engine Light and Factory Diagnostic Plug which can be scanned by any shop with the right equipment. We also offer Holley ECM Controllers and harnesses for automatic or manual transmissions as well as FAST Electronics and Comp-U-Shift transmission controllers. Along with the LS engines harness, SPS now offers Harnesses and ECM Programming for the LT1 line.
