This 1962 Chevrolet Biscayne started life as a basic full-size model but has been transformed into a sleeper project car with the installation of a powerful 454 cubic-inch V8 engine and automatic transmission. While the exterior and interior still need significant work, the mechanical upgrades make this Biscayne an enticing find for hot rod enthusiasts looking for speed in a larger package.

Why it matters

The Biscayne was Chevrolet's most affordable full-size model in the 1960s, making it a popular choice for budget-minded buyers and hot rodders seeking a blank canvas to build their dream car. This particular Biscayne has been given a big-block engine swap, turning it into a stealthy high-performance machine that flies under the radar.

The details

This 1962 Chevrolet Biscayne is equipped with a robust 454 cubic-inch V8 engine and a TH-400 automatic transmission, providing substantial power upgrades over the original inline-6 and manual transmission setup. However, the body and interior still require significant restoration work, including addressing rust issues in the floorboards and repainting the exterior. The seller notes that all the trim pieces are present, and some interior components have been replaced, such as a set of bucket seats.

  • The car has been garaged for over 10 years, according to the seller.
  • The odometer is approaching 100,000 miles, though the mechanical upgrades may have reset the mileage.
