This intake with Edelbrock carbs and the listed air cleaners have the following dimensions: 3251235 is nearly 10” 3251237 is 10 ¾” 3254119 is 11 ¾” These dimensions are approximate and can vary slightly with the carb to manifold gasket and intake gasket set. You may want to confer with Edelbrock direct for a listing of possible applications that may include your 1970 Nova.
