GM LS & Gen-V LT engines make great power and are ideal for engine swaps in the 1963-67 GM C10 Trucks. Hooker BlackHeart application-specific LS/LT swap engine mounting brackets remove the installation guesswork and compatibility uncertainty that comes with using universal/adjustable swap plates. These brackets are designed for 1963-1967 GM C10 pick-ups to achieve optimized component clearances and drivetrain/U-joint operation angles when used in conjunction with 71222024HKR, 71222024HKR-1, or 71222024HKR-2 transmission crossmember and Hooker cast exhaust manifolds and dual exhaust systems co-developed for this application. These motor mounting brackets fit both the LS & LT engines, and allow a future engine upgrade by changing the clamshell that attaches to the engine (when upgrading from LS to LT engine). These brackets are for use on trucks with the wide style frame rails.
Features:
- Welded Steel Construction w/Black Finish
- Light Weight Rigid And Clean Appearance
- Black Coating For Durability And Corrosion Resistance
- Includes Mounts/Instructions/Mounting Bolts
- Use With 4th Gen GM F-body Style Clamshell Engine Mounts
Holley Performance Emission Code 5: This part is legal for sale or use on Emissions Controlled Vehicles; Uncontrolled (Non-Emissions Controlled) Vehicles; and Racing Use Only Vehicles because it does not affect vehicle emissions and is not covered by emissions regulations
Installation Notes:
These mounts fit C10 trucks with the Wide Frame Rails - see the photograph to help identify which style frame rail in on your truck.
C10 Trucks with Narrow Frame Rails use part number BHS511. In most cases, the narrow frame rails were used on 1968-72 trucks to accommodate big block engines, but some trucks may have been had the frame swapped at some point after it left the factory.
Installation of these brackets requires the use of BlackHeart LS/LT Polyurethane Inserts - P/N's 71221016HKR (Black) or 71221017HKR (Red) along with Hooker Blackheart 71221018HKR heavy duty clamshells A substitution of O.E. 4th-gen F-body LS engine mounts (ex: GM 22179268 or Anchor 3064) can also be used. Also requires Blackheart 71223015HKR engine mount bolt kit to connect the Hooker engine brackets to the motor mounts. Specification requirements are 10.9 M12 x 1.75 x 140mm.
Use 302-2, or 302-3 oil pans w/ LS Engines, and 302-20 w/ Gen-V LT engines.
Allows Use of Low Mount A/C.
