LS and LT Radiator for 1973-1974 Chevy Nova/Ventura X-Body
Swapping an LS or LT powerplant into a 1973-1974 Chevy Nova or Pontiac Ventura demands a cooling solution that mates cleanly with original X Body supports and ports. The 1984-1989 Corvette Radiator (Auto and Manual Trans) offers a direct fit by matching factory fill neck and bracket locations without the need for adapters. Its fully TIG welded aluminum core and tanks stand up to corrosion while guiding coolant through an optimized fin layout for steady temperature control under load. Made in the USA to precise specifications, this radiator also preserves clearance around belt driven pulleys and transmission connections for straightforward installation and dependable service on the road.
Ultimate TIG Welded Construction for Unmatched Durability
This Corvette radiator features complete TIG welding on every joint, delivering precision control over weld bead and penetration depth. By fusing high quality aluminum tanks and core channels without filler material contamination, the assembly resists leaks when the cooling system reaches high temperature under load. The seamless bonds also stand up to vibration and pressure fluctuations common in LS and LT engine installations. Each weld joint is inspected in the USA to ensure uniform quality and long service life, providing peace of mind for builders seeking a reliable cooling foundation.
Optimized Aluminum Core Architecture for Superior Cooling Response
Crafted from high quality aluminum, the core employs a balanced channel profile and dense fin arrangement to maximize heat transfer from coolant to airflow. Aluminum's thermal conductivity enables rapid rejection of engine heat, a key advantage when pushing modern LS or LT powerplants at sustained output. The lightweight design reduces front end mass, enhancing steering feedback and chassis dynamics without compromising capacity. Whether cruising long distances or tackling spirited driving, this core maintains coolant temperature within safe limits.
Engineered Direct Bolt In Fit for 1973 to 1974 X Body Chassis
Designed specifically for the Chevy Nova and Pontiac Ventura X Body platform, this radiator matches original bracket locations and fill neck placement with no adapter plates required. Automatic and manual transmission models both benefit from preserved clearance around belt drives and transmission lines, avoiding any interference during installation. Builders appreciate eliminating frame rail trimming or port relocation, as the unit aligns exactly with factory supports. This direct integration simplifies assembly and maintains the classic engine bay appearance.
Finish Options Combining Protection and Visual Appeal
Available in classic bare aluminum or a durable black epoxy coat, this radiator lets builders choose between an industrial metallic look or enhanced surface defense. The natural aluminum surface forms its own protective oxide layer, slowing corrosion while showcasing clean weld details. In contrast, the epoxy film resists chips, road debris, and exposure to moisture without cracking under repeated temperature cycles. Both finishes undergo rigorous quality checks to confirm even coverage and full compatibility with original X Body mounting points.
