The owner of this ’64 Nova SS came in wanting modern power and reliability. We opted for an LT4 swap with a Gen 5 Whipple, but we didn’t stop there. Custom headers, a full 3.5” oval exhaust, a Holley dash integrated into the factory bezel, and plenty of other custom work throughout.

A lot went into making modern power and technology feel right at home in a ’64 Nova. No shortcuts on this one.
