Show original supplier description
The BRP Hot Rods LSX21 is a comprehensive conversion kit engineered for installing LS engines and 4L60E transmissions into 1962-1967 Chevy II Nova models. This careful alignment minimizes vibrations, contributing to quieter operation and extended component lifespan. The kit is directly compatible with the Moroso GTO oil pan, offering flexibility for low-profile sumps without chassis interference, and attaches with factory-style hardware. Installation is simplified with a direct-fit design that requires no tunnel modifications for the 4L60E transmission. Factory bolt patterns align with the vehicle floor, and the kit's geometry supports correct driveshaft angles without trimming or clearance issues. The transmission rails and mounting brackets integrate seamlessly with existing chassis points for a clean installation that respects the original frame structure. T56 transmissions will require adjustments. The package includes two motor mounts, four frame bracket plates, a transmission crossmember, a polyurethane transmission mount, and a complete installation hardware pack.
