MuscleRods LS Engine Swap Kit for 1965-1970 B-Body Chevy Impala
If you're planning an LS swap into your 1965 to 1970 Chevy Impala, fitting the engine and gearbox without altering the tunnel is the toughest hurdle. MuscleRods designed the 1965 to 1970 B Body LS Conversion Kit to provide precision engine and transmission mounts along with a crossmember that fit the factory tunnel without modification. By preserving the original drivetrain angle, the kit keeps vibrations low and protects universal joints from added stress. Builders will appreciate that the kit drops into place for 4L60E or 4L80E transmissions while clearing most oil pans and maintaining correct driveshaft alignment.
Precision Engine and Transmission Alignment
This kit features motor and frame brackets engineered to position the LS engine and 4L60E or 4L80E transmission at the factory driveline angle. By preserving that angle it minimizes vibration transmitted into the chassis and reduces stress on universal joints. Installers can achieve consistent results without extensive trial and error, ensuring smooth power delivery and lower risk of driveline fatigue over time.
Robust Steel Construction for Reliability
Brackets and the crossmember are laser cut from thick steel plate and TIG welded for exceptional strength. This manufacturing process prevents warping under load or during heat cycling so the kit maintains its shape even in demanding use. A durable finish resists corrosion and road debris, contributing to long-lasting support for the powertrain. Builders can count on unwavering structural integrity without concern for bracket flex or failure.
Optimized Clearance for Modern LS Oil Pans
The transmission crossmember is shaped to clear most Gen III and Gen IV LS oil pans when paired with a high clearance or retro style pan option. This allows direct installation without modifying the tunnel or altering chassis structure. Maintaining correct driveshaft angles preserves driveline geometry and cuts installation time. Engine builders can choose popular oil pans like the Moroso high clearance or the cast aluminum retro unit with confidence.
Complete Hardware Package for Streamlined Installation
This swap kit includes motor mounts, frame brackets, the crossmember and outer supports, a polyurethane transmission mount with spacers, plus a full hardware pack. Numbered components and clear instructions eliminate guesswork and ensure each piece is installed in the proper sequence. Builders no longer need to source bolts or adapters, making the project efficient and dependable. It supports 1965 through 1970 Chevy Impalas straight out of the box.
