1984-1991 Corvette LS Engine Mounts Overview
These mounts are engineered specifically for 1984 through 1991 Corvette chassis when fitted with LS powerplants. Manufactured in the United States from corrosion resistant alloys, they deliver lasting performance under real world conditions. Installation preserves stock frame clearances and maintains correct alignment with factory subframes. Support extends to both modern LS conversions and original L98 or LT1 engines, ensuring a direct swap without additional modifications. Precision machining of the mounting faces and tolerance control reduces vibration transmission and secures the engine in its optimal running position.
Fuel Pump and Fitting Kit
The assembly includes a Walbro 255 LPH in tank fuel pump designed to meet the demands of returnless fuel systems on daily driven and enthusiast vehicles. Its high flow capacity ensures stable fuel pressure under acceleration, minimizing the risk of lean condition at high loads. A Corvette specific fitting set is provided to match the factory fuel line routing and retain original mounting points, eliminating the need for custom adapters or fuel hose rework. This approach streamlines installation, preserves stock emission hardware, and supports both factory engine control modules and popular calibration upgrades.
