LS and LT Radiator for 1973-1974 Chevy Nova and Pontiac Ventura
When you swap a modern LS or LT powerplant into a 1973 to 1974 Chevy Nova or Pontiac Ventura, you need a radiator that aligns with original X body supports and ports. The 1984 through 1989 Corvette Radiator delivers a direct bolt in fit for both automatic and manual trans models by matching factory locations without adapters. Fully TIG welded aluminum tanks and core resist corrosion while promoting steady coolant flow through an optimized fin layout for rapid heat rejection under load. Clearance is preserved around belt driven pulleys and transmission connections and each radiator is made in the USA with precise inspection to maintain fitment accuracy and durable operation during highway runs or spirited driving.
Precision TIG Welding Ensuring Leak Free Operation
This radiator uses complete TIG welding on all aluminum seams to achieve meticulous control over bond line and penetration depth. TIG welding delivers clean weld beads without slag or porosity that can lead to coolant loss when the engine runs at high temperature. By forming a robust mechanical link across every joint, the assembly resists stress from vibration and pressure spikes in LS or LT installations. Each weld partner is inspected in the USA to maintain consistent quality and seal integrity for reliable performance under load.
Aluminum Core Design for Rapid Heat Rejection
Built from high quality aluminum, the core features a precision fin layout and balanced channel thickness to maximize heat transfer from coolant to incoming air. The thermal conductivity of aluminum combined with an open channel design allows fast rejection of excess engine heat, a key advantage when powering modern LS or LT engines at sustained load. Its lightweight construction reduces front end mass for a more responsive chassis feel without sacrificing cooling capacity. This design maintains stable temperatures during extended highway cruising or spirited acceleration.
Versatile Finish Options for Protection and Style
Available in bare aluminum or a black epoxy finish, this radiator offers builders a choice between classic metallic style and enhanced surface protection. The natural aluminum surface self passivates to slow oxidation while showcasing weld details and fin craftsmanship. In contrast, the epoxy coat creates a tough film that resists chips, road debris, and weather exposure while still handling thermal cycling without peeling. Both finishes undergo strict inspection to ensure even coverage and full compatibility with X Body mounting points and transmission connections.
Direct Fit Installation on 1973 to 1974 X Body Frames
Designed specifically for the Chevy Nova and Pontiac Ventura X Body chassis from 1973 to 1974, this radiator aligns precisely with original support brackets and coolant ports. No adapter fittings are required for automatic or manual transmission models, and clearance is preserved around belt driven pulleys and transmission lines. Builders will appreciate the simple bolt up process that avoids trimming or modification of the frame rails. By matching factory fill neck and mounting foot locations, the unit integrates seamlessly into the original cooling system layout.
