Stay Cool and Look Factory with a Johnson’s Radiator Works Engine Swap Radiator

So you did an engine swap in your early Ford hot rod, ‘60s muscle car, or classic truck. You’d like to use an OEM-style copper-brass radiator but want to be double-sure it will keep the engine running nice and cool like an aluminum radiator would.

Assuage your concern by installing a Johnson’s Radiator Works Engine Swap Radiator. They’re made in-house at Johnson’s Hot Rod Shop using original tooling from Walker Radiator, the pioneer in copper-brass hot rod radiators.

The radiators have a high-flow, 2 3/4-inch thick copper core with four rows of 1 1/4-inch by 1/2-inch brass tubes and over 600,000 louvers to keep any engine short of a full-on race motor nice and cool. They require no modifications to core support, grille or grille shell—the radiators are a drop-in installation and mount using heavy-gauge galvanized steel brackets help eliminate the chance  of cracking or leaking.

Other features include:
• One-piece top tanks stamped from .040-inch brass
• Brass petcock
• Most radiators use 15- to 18-pound radiator cap (early flathead Fords use seven-pound cap)
• Many applications available with a built-in transmission cooler

Johnson’s Radiator Works Engine Swap Radiators are available for Ford and GM vehicles from 1917 Model Ts to 1987 GM squarebody trucks in configurations for small and big block Chevy, small and big block Ford, and GM LS engines.

Summit Racing also has radiators for 1994-2007 GM 1/2-ton trucks and 1982-93 S-Series trucks with a Gen 1 small block Chevy, big block Chevy, or LS engine.
