The big 389 was good for 325 hp, 348 in Tri-Power guise. Putting big engines in little cars became the American way and gave birth to several iconic muscle cars in the 1960s and 70s.

High-horsepower street cars and trucks can be a real challenge to keep cool, and any good cooling system starts with choosing the right radiator. Aluminum radiators cool more effectively and weigh less than ordinary OEM-style brass units.
