1973-1974 Nova and Ventura Radiator for LS and LT Engine Swaps
Tackling an LS or LT engine swap in a 1973-1974 Chevy Nova or Pontiac Ventura manual transmission puts extra thermal demands on the stock cooling system and the 1973-1974 Nova Radiator (Manual Trans) is designed to deliver the coolant flow needed within the tight X body frame. Engineered with 100% TIG welded aluminum tanks and core in the USA, this radiator installs at stock mounting points with no cutting or bending required. A choice of bare aluminum or black epoxy finish ensures lasting corrosion resistance while retaining clearance for factory fan assemblies and hoses for a straightforward installation.
Precision TIG welded aluminum assembly
Derived from a controlled fusion process, the 100% TIG welded high grade aluminum tanks and core deliver unmatched joint consistency. By applying a stable arc to fuse sections, the method minimizes stress points and creates leak proof seals that withstand the constant expansion cycles of an LS or LT engine. The uniform welds also preserve ductility, so the radiator can tolerate rapid temperature swings without cracking. Manufactured in the USA, this precise assembly ensures lasting structural integrity for daily driving or track use.
Exceptional heat dissipation with aluminum core
An all aluminum core capitalizes on the metal’s superior thermal conductivity to pull heat away from the engine block quickly and evenly. Compared to traditional copper and brass units, the lighter core reduces front end mass while maintaining rapid coolant cooling, which keeps operating temperatures stable under load. Corrosion resistance inherent to aluminum helps preserve flow rates over years of service, ensuring that an LS or LT swap remains tuned for peak performance. The design supports spirited driving and stop and go traffic without sacrificing reliability.
Fitment tailored for X Body frame
Specifically engineered for the 1973-1974 Nova and Ventura X Body chassis, this radiator drops into place using original style mounting brackets and inlet locations. No cutting or bending is required to clear factory hoses and fan assemblies, enabling a straightforward installation at stock mounting points. Precision machined ports guarantee perfect alignment with a manual transmission configuration, reducing install time and eliminating fitment frustration. This ensures compatibility and consistency whether you're installing in a garage or a professional shop.
Protective finishes for corrosion resistance
Choose the classic bare aluminum for a period correct appearance or opt for the black epoxy finish to add a durable barrier against moisture and road chemicals. Each coating is applied uniformly to seal the surface against pitting and oxidation, preserving both the look and function of the radiator over time. The finishes ship ready to install, so you can protect your cooling investment without additional prep work. This approach balances style and long term resistance to the elements.
