MuscleRods LT Engine Swap Kit for 1958-1964 Impala B-Body
Keeping coolant temperatures in check during a Gen V LT swap into a 1958-1964 Impala B Body is crucial so the 1973-1974 Nova Radiator (Manual Trans) with Fan delivers reliable heat dissipation tailored to manual transmission setups. This radiator assembly integrates directly with the existing frame rails in the MuscleRods Engine Swap Kit and mounts without chassis modifications to retain factory underbody clearance. With precision brackets and an electric fan shroud designed to clear suspension and steering components, it ensures optimal coolant flow under sustained load and offers corrosion resistant construction for lasting performance.
Precision Crafted Bracket Integration for LT Engine Placement
Each bracket in this swap kit is CNC cut from domestic steel plate to exact tolerances, ensuring the Gen V LT engine centers perfectly within the Impala B-Body frame. The consistent thickness and flat surfaces maintain the crankshaft centerline in alignment with the transmission input, preserving driveline geometry under all conditions. By eliminating guesswork during installation, this precise fit reduces vibration transfer into the cabin and protects seals and bearing surfaces from premature wear. Technicians find that maintaining true engine orientation also speeds up calibration of the engine control system and throttle mapping. These engineered mounts deliver a balanced power curve and a refined driving character without modifying the chassis or undercarriage.
Reinforced Crossmember Ensuring Frame Stability
The heavy gauge steel crossmember spans the original frame rails to form a rigid backbone capable of handling increased torque from modern LT engines. Designed using finite element analysis, it resists bending under cornering loads and rapid throttle application, preserving the original rail spacing without altering factory geometry. The bolt-in installation requires no cutting or welding, so the Impala's underbody clearance and classic contours remain intact. A corrosion resistant finish protects the assembly from moisture and road debris, extending its service life. This robust support structure prevents fatigue and distortion that can occur when fitting a higher output powerplant into an aging chassis.
Universal Transmission Mount for 4L60E and 4L80E Applications
This pre-assembled transmission mount arrives ready to accept either a 4L60E or a 4L80E unit, removing the need for custom fabrication or excessive trial fitting. Pre-positioned inserts and factory-style hardware align perfectly with stock frame holes, preserving the transmission tunnel and maintaining interior clearance. Installers simply set the mount in place, secure the bolts, and proceed to connect the driveline with confidence that anchor points are correct. By avoiding floorpan trimming, the original structure stays intact and noise-vibration-harshness levels remain low. The secure fit also reduces stress on seals and splines, contributing to leak-free performance under sustained load.
