Holley Performance Announces LS/LT Swap Kits and Headers for 1988-98 Chevy/GMC OBS Trucks

 

Over the last several years, the OBS (old body style) 1988-98 Chevy and GMC trucks have been picking up interest in the hot-rodding community. Particularly, in the LS swap world, where LS and GEN-V LT engines are the powerplant of choice for street/strip trucks and those looking to take a pickup through the corners in the pro-touring world.

Of course, hot-rodders have been implementing old school tricks and off-brand components to make these swaps possible, but it’s time for a quality manufacturer to enter the fray, and that’s where Holley Performance comes in. They’ve expanded on their vast catalog for LS/LT speed parts and components with these LS/LT headers and mounting brackets for 1988-98 C/K1500 GM trucks.

Official Release:

Hooker BlackHeart GM LS and Gen-V LT Engine Mounting Brackets for 1988-1998 GM C1500/K1500 (2WD and 4WD 1/2-ton Truck)

Hooker BlackHeart application-specific LS/LT swap engine mounting brackets eliminate the installation guesswork and compatibility uncertainty that comes with using universal swap plate mounting methods. These mounting brackets are available with forward-bias, rearward-bias, or dual engine mounting positions that optimize powertrain placement based on user-selected transmission, transfer case and driveshaft compatibility/retention priorities.

The factory transmission crossmember is re-used with these mounting brackets (cost savings since driveshafts and crossmember are re-used).

Factory LS Vortec exhaust manifolds can be used along with the engine mounting brackets and are required to support a street-legal engine change (with catalytic converters). Off-road racing applications can use Hooker BlackHeart BH13266 LS Swap Headers or BH 13272 LT Swap Headers. Mounts feature a black powder-coated finish and include (2) engine mounting brackets, attaching hardware and instructions.
