LS and LT Radiator for 1973-1974 Chevy Nova and Pontiac Ventura Manual Trans
Taming the extra heat from an LS or LT swap in a 1973-1974 Chevy Nova or Pontiac Ventura manual transmission starts with a radiator engineered to fit its tight X body framework. It features TIG welded aluminum tanks and core made in the USA for direct fit at stock mounting points, ensuring efficient coolant flow. The unit installs without cutting or bending thanks to OE style brackets and clearance for factory fans and hoses. Available in bare aluminum or black epoxy finish, this radiator balances practical cooling performance with period correct style under the hood.
Precision TIG Welded Aluminum Construction
The radiator's 100% TIG welded tanks and core deliver unmatched consistency and strength at each joint. By fusing high-grade aluminum in a controlled arc process, stress concentrations are minimized and leak points are virtually eliminated. This construction method also preserves the metal's inherent ductility, allowing the assembly to accommodate thermal expansion without cracking. Manufactured in the USA, the precise welds ensure a sturdy foundation that stands up to track days or daily driving alike.
Optimized Thermal Efficiency with Aluminum Core
An all-aluminum core excels at transferring heat away from the engine block, reducing coolant temperature in heavy traffic or spirited runs. Aluminum's high thermal conductivity promotes rapid heat rejection, while the lightweight design lessens front-end load compared to traditional copper-brass units. The result is a cooler operating range for LS or LT engines in a '73-'74 Nova or Ventura, improving performance consistency and extending component life. Corrosion resistance inherent to aluminum further maintains peak flow rates over years of service.
Dual Finish Options for Protection and Aesthetics
Choose between a classic bare finish or a black epoxy coating to match your engine bay theme. The bare aluminum option highlights raw metal for a period-correct appearance, while the epoxy layer provides an extra barrier against road salts and moisture. Each finish applies a uniform protective film that resists pitting and surface oxidation, ensuring the radiator retains its visual appeal over time. Both options ship ready to install, so styling and safeguarding your investment take equal priority.
Direct Fit Design and Installation Ease
Engineered to slip into the Nova or Ventura X-Body frame without cutting or modification, this radiator uses OE style mounting brackets and inlet locations. Clearance for factory fan assemblies and stock hoses means no fabrication or rerouting is required. Installers benefit from precise hole alignment and consistent port spacing, cutting install time and eliminating fitment headaches. Whether you're a seasoned technician or a home enthusiast, the straightforward setup guarantees a smooth upgrade.
