Simplify Your 1958-1964 Chevy Impala LS Conversion with MuscleRods

For a seamless LS installation in your 1958-1964 Chevy Impala B-Body, the MuscleRods Engine Swap Kit provides precision mounts and F-Body oil pan integration to preserve chassis geometry and avoid time consuming tunnel modifications. Compatibility with T56, 4L60E or 4L80E transmissions and all hardware proudly made in the USA deliver dependable performance and vibration free cruising.

MuscleRods LS Engine Swap Kit for 1958-1964 Chevy Impala

Swapping an LS into a classic Chevy Impala from 1958 to 1964 often reveals alignment challenges the B-Body frame wasn't built to handle. The 1958-1964 B-Body LS Conversion Kit from MuscleRods secures your LS engine and transmission crossmember in the factory frame rails, reducing the need for tunnel work or aftermarket brackets. Prefabricated engine and frame mounts streamline installation, while support for T56, 4L60E and 4L80E transmissions lets you focus on wiring and plumbing rather than fabricating brackets.

Precision Alignment and Vibration Control for Your B-Body Chevy

The conversion kit is engineered to maintain the correct drivetrain angle between your LS engine and transmission mount. By holding the powertrain at factory spec, this alignment minimizes driveline windup and reduces vibration feedback into the frame. That precise geometry not only improves shifting feel but also extends the life of universal joints and transmission bearings. Enthusiasts will notice a marked improvement in smoothness both around town and on spirited drives.

Streamlined Installation with Comprehensive Component Set

This all in one kit delivers engine mounts, frame mounts, crossmember brackets, a transmission mount pack and all required hardware. Each piece is preformed to bolt into the factory frame rails without cutting or welding the floor structure. Builders save hours of mockup and bracket fabrication, allowing focus on wiring and plumbing. The included parts work together to ensure a snug fit under the hood without last minute modifications.

Versatile Transmission and Engine Pairing

Supporting T56, 4L60E and 4L80E transmissions, this kit gives you freedom to choose your preferred gearbox with minimal modifications. The crossmember and transmission mount accept the bolt patterns of these three popular units while keeping the driveline angle right where it belongs. Compatible with most Gen III and Gen IV LS engines, the kit works with an oil pan style common to GM F series muscle cars and a suitable intake for hood clearance. Minor tweaks may be needed for other transmission types.

Quality Assurance Through USA Production

Every component in this engine swap kit is manufactured in the United States under strict quality control standards. Sourcing locally allows tighter tolerances on bracket geometry and faster feedback loops with fabricators. The result is a reliable setup that resists fatigue and stands up to daily driving or spirited runs. Choosing domestically produced parts also supports a supply chain that can deliver consistent components for future maintenance and upgrades.

Not an add on, but a more robust kit where you can build this same kit but this is a customizable kit where they can select their own parts to better suit their needs, see our Complete LS Swap Kits - LS Kit Builder. Count on MuscleRods quality for confident performance.
