Complete MuscleRods LS Conversion Kit for 1958-1964 Chevy Impala B-Body
Whether you're fitting an LS powerplant into a 1958-1964 Chevy Impala B-Body or pairing a T56, 4L60E or 4L80E gearbox for improved drivability, the 1958-1964 B-Body LS Conversion Kit eliminates fitment guesswork. It secures LS engines at a precise angle to factory rails and aligns F-Body oil pans under the stock hood line without modifications to the transmission tunnel. Made in the USA and supplied with two motor mounts, two frame mounts, one transmission crossmember, two outer crossmember brackets, one polyurethane transmission mount with optional spacers, and an installation hardware pack, it guides every component for confident installation.
Precision Fitment for 1958 to 1964 B-Body
The 1958 to 1964 B-Body LS Conversion Kit is engineered specifically for Chevrolet B-Body vehicles from 1958 to 1964. Every bracket and spacer aligns with original frame rails to guarantee a true fit without chassis alteration. This tailored design preserves the iconic stance and road clearance of the factory platform. By matching factory mounting points, time spent on trial fits is eliminated. The kit retains proper engine tilt for reliable oil delivery and helps avoid crankcase stress.
Transmission Versatility and Drivetrain Stability
Compatibility with T56, 4L60E and 4L80E transmissions expands engine and gearbox choices. MuscleRods recommended mounts ensure correct alignment and preserve driveline angles. Maintaining the factory angle prevents unwanted vibration and prolongs component life. No transmission tunnel modification is required, so interior integrity remains intact. The retention of factory structural points bolsters assembly strength and durability.
Seamless Engine and Oil Pan Integration
The conversion kit accepts an F-Body oil pan to clear frame rails and suspension components. Integration accuracy allows the pan to sit flush and maintain proper fluid capacity. Precision machining on the adapter reduces the risk of leaks or misalignment. By reusing proven pan design, you benefit from existing service knowledge and aftermarket support. This approach avoids clearance conflicts and simplifies maintenance access.
American Craftsmanship and Production
Each component is proudly made in the USA by skilled machinists. Material selection and finish processes resist corrosion and wear over time. Robust hardware and stamped brackets deliver consistent performance under load. Factory quality checks ensure each kit meets strict tolerances before shipping. Domestic production supports rapid fulfillment and local supplier networks.
