1968-1972 A-Body Radiator for LS and LT Engine Swaps
If your build involves an LS or LT powerplant with an automatic transmission in a 1968 to 1972 A Body or 1970 to 1972 Monte Carlo chassis, this radiator addresses cooling challenges with precise fitment and sustained flow. It mounts on Chevelle, Skylark, Cutlass, GTO, Le Mans and El Camino frames and features a full aluminum core rated at 400 lph. Engineered to withstand more than 550 hp on forced induction setups, it delivers high heat rejection while remaining light weight. Available in bare aluminum or black epoxy, each unit is built in the USA for consistent fit and durability.
Precision Aluminum Construction
The radiator is crafted from quality aluminum in the USA to deliver firm resistance to corrosion and efficient heat dissipation. Its core and end tanks are fully welded to maintain structural integrity under high heat loads. This choice of material not only reduces overall mass but also enhances longevity when paired with high horsepower supercharged engines. By relying on a solidly brazed assembly, the design withstands constant thermal cycling without compromising coolant containment or performance.
Dedicated Fitment for A Body and Monte Carlo Models
Engineered specifically for 1968 through 1972 A Body vehicles and 1970 through 1972 Monte Carlo cars equipped with automatic transmissions, this radiator delivers a precise fit without modification. The inlet and outlet ports, as well as the mounting feet, match factory dimensions for LS or LT engine installations. By eliminating the need for custom brackets or hose alignment issues, the design reduces installation time and helps maintain original firewall clearance for restorations or performance upgrades.
Integration with MuscleRods Mounts
This radiator integrates seamlessly with the MuscleRods mounting system to ensure proper engine placement and accurate drivetrain angles. Precision alignment between the engine block and transmission case prevents stress on cooling hoses and supports consistent coolant flow. This partnership also allows for correct fan shroud positioning and reliable fan operation, guaranteeing safe clearance from rotating components even under heavy load or sudden throttle transitions.
Optimized Cooling for Enhanced Performance
Designed to support high horsepower setups and forced induction systems, this radiator features a high capacity core that maximizes coolant volume and flow rate. The increased surface area and optimized fin pattern work together to manage heat rejection during sustained hard driving. Whether tackling track days or spirited weekend runs, the stable temperature control prevents heat soak in critical areas and allows the engine to operate at peak power output throughout extended sessions.
