LS/LT Swap Engine Mount Brackets for 1988-98 C1500

Hooker BlackHeart

Regular price $279.95

Level 7 Motorsports has found what we believe is the perfect set of LS/LT swap mount brackets for the 1988-98 OBS Chevy platform. We use this set of brackets here in the shop and love the stock location of the engine. It gives plenty of clearance for the steering shaft, accessory drive, and intake pipe. We also offer a Level 7 exclusive set of OBS specific swap headers to use in conjunction with these engine mounts.

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, or rearward-bias 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 BH13272 Gen-V LT Swap Headers. Mounts feature a black powder-coated finish and Include (2) engine mounting brackets, attaching hardware and instructions.
