Official Release:
1978-1988 GM G-Body LS and LT Swap Engine Brackets and Transmission Crossmember Adapters
The entire Holley swap system (brackets, mounts, oil pans, accessory drives, etc.) is designed to decrease your total swap installation effort and cost, while increasing the engineered quality of your vehicle and compatibility of these components with other popular aftermarket components.
The experts at Hooker BlackHeart have taken away the guesswork of where to position your engine swap and we’ve followed up on our popular GM G-Body LS line with a new version that allows you to choose LS or LT engines by utilizing 4th Gen F-Body clamshell engine mounts. To complete the engine mounting be sure to follow these steps:
1). Choose the proper clamshell for your engine: Gen III/IV (LS) – 71221018HKR Gen V (LT) – 71221019HKR
2). Add the thru bolt kit: GM LS/LT/Gen III Hemi – 71223015HKR
3). Choose the polyurethane insert in the color you prefer: Black – 71221016HKR Red – 71221017HKR
Features:
- When coupled with the Hooker BlackHeart transmission crossmembers 12644HKR-1, these mounting brackets locate the engine in the same nominal position (fore-aft, height, offset, etc.) as the original engine
- Easily switch between LS and LT engines through a simple change of the necessary 4th Gen F-body clamshell engine mounts: 71221018HKR for LS and 71221019HKR for LT. Polyurethane inserts are the same for LS or LT.
- Provides compatibility with many accessory drives: Holley Corvette style, Holley F-body style, OE Corvette, OE F-Body, OE GTO, OE Vortec Truck
- Works with Hooker BlackHeart 8501HKR, 8502HKR, and 8503HKR (LS) and BHS516 and BHS3116 (LT) exhaust manifolds
