1964-1967 Chevelle A-Body LT Swap Simplified by MuscleRods

Precision mounts form the backbone of the 1964 through 1967 A Body LT Conversion Kit, ensuring perfect alignment and minimal vibration in your classic Chevelle. Reinforced frame brackets and custom transmission supports deliver long-lasting chassis strength and optimized power transfer, while construction in the USA and expert assistance from MuscleRods guarantee a smooth installation and improved drivability.

MuscleRods LT Engine Swap Kit for 1964-1967 Chevy Chevelle A-Body

When installing a Gen V LT engine in a 1964 to 1967 Chevelle A Body chassis maintaining correct engine position and angle is essential to prevent chassis stress and driveline misalignment. This 1964 to 1967 A Body LT Conversion Kit features custom brackets and engine mounts designed by MuscleRods to hold the LT block at the ideal height while allowing GM 4L60E and 4L80E transmissions to drop in without altering the floor tunnel. Every bracket and crossmember is made in the USA to reinforce frame rails under torque reduce vibration transfer and preserve drivetrain alignment for consistent power delivery. Installers will appreciate predrilled holes that line up with factory block bosses eliminating the need for shims or fabrication during the swap.

Precision Chassis Alignment for 1964 1967 Chevelle A Body Installation

The conversion kit's custom brackets are machined to match the 1964 through 1967 Chevelle A Body frame rails with tolerances measured in thousandths of an inch. Predrilled mounting points line up directly with factory block bosses, eliminating the need for shims or on site fabrication. This exact placement maintains ideal driveline geometry under all load conditions, reducing stress on universal joints and transmission linkages. By keeping the engine block square to the chassis, vibration transfer to the cabin is minimized, resulting in a more refined driving feel and longer component life.

Optimized Engine Mount Geometry for Gen V LT Powerplants

Engine mounts in this kit cradle modern Gen V LT engines at the precise height and angle recommended by OEM guidelines, ensuring the block sits squarely in the factory motor bay. Each bracket features robust gussets and fully welded joints designed to withstand the torque spikes experienced during launch and spirited acceleration. Proper orientation prevents unwanted movement of key components such as water pumps and accessory drives, dramatically reducing premature wear from misalignment. The mounts also isolate noise and vibration before they reach the passenger compartment, delivering a quieter ride without sacrificing structural support.

Reinforced Frame Brackets and Cross Member for Torque Control

The heavy gauge brackets and precision fabricated cross member work together to spread engine load across a larger section of the frame rails, resisting flex during peak torque events. Strategic weld patterns ensure repeatable strength at each joint, preserving suspension geometry and steering precision even under hard acceleration or cornering. A raised clearance profile within the cross member accommodates factory header designs without compromise, so exhaust flow remains unrestricted. With chassis rigidity maintained, uneven tire wear and frame distortion are greatly reduced over the life of the vehicle.

Efficient Transmission Support for 4L60E and 4L80E Applications

This transmission mount assembly positions GM 4L60E and 4L80E gearboxes at the factory tunnel height, allowing direct installation with no floor modification required. An integrated isolator cushions driveline torque, smoothing shift engagement and reducing snap between gears for a more predictable heel toe experience. Correct spacing between block and case also protects sealing surfaces from undue tension, preventing leaks and seal failures. The versatile design accepts minor hardware adjustments for other transmission models and includes a full set of installation fasteners to guarantee precise alignment out of the box.
