Squarebody Gen V (L83/L86) Conversion Kit


Share this:



Install a GM L83 or L86 V8 into your ’73-’91 GM full size truck, WITH FACTORY ACCESSORIES.

This kit includes proven Tejas SteelWorks engine mounting brackets, high clearance transmission cross-member, urethane transmission cushion, Tejas SteelWorks own power steering bracket, power steering pump with integral reservoir, pulley, accessory drive belt, power steering hoses and hardware.

It is necessary to delete the vacuum pump in order to mount the power steering pump. You retain the original waterpump, alternator, A/C compressor and accessory drive. We allow you to add a hydraulic power steering pump and provide the supporting parts to complete this install.

Choose the year of truck and transmission option from the drop down menu. ’73-’80 models use SAE inverted flare fittings on the hoses, ’81-’91 models use metric o-ring fittings. 4wd applications use the same kit, minus the crossmember and transmission mount. A hydraboost option is available on the pump, though customer will need to provide the pressure hoses to and from the booster as these can vary.
