509 Big-Block Engine Install for 1968-1974 Chevy Nova's - What A Drag, Part 2 Photo Gallery
We love the look of the 509 Dart nestled in the engine compartment, along with the TCI tubular front end components. The Proform 950 has vacuum outlets, which enabled us to run a 3/8-inch vacuum hose to the brake booster and the PCV valve. Other 950 carbs don't feature timed and full vacuum tubes. You can hear the 509 running and see the Nova's first drive on the Super Chevy magazine website-click on videos section.
