The difference in 'Shipping Weight' was not that much, only {72 lbs.}. * 1967 Coronet Deluxe...... #3388 lbs. * 1968 Super Bee............. #3460 lbs.
Book Horsepower on the 1967 383 4-Barrel was 325 HP, but it was much closer to 280 to 290 Horsepower.
* #516 Cylinder Heads with a 1.60" Exhaust Valve. * Restrictive Exhaust System * Mild Camshaft {Same as 383 2-Barrel} * Weak Valve Springs * Low-profile Intake Manifold with poor flowing Runner-Ports * Carter AFB {575 CFM}
All you have to do is look at the 'anemic' Production Numbers, and you could tell that the 1967 383 was 'not' a Street Musclecar.
Grand Spaulding Dodge {Mr. Norm's} did have an 'Upper Engine Kit', for the 383 which included; * Racer Brown Camshaft 'Hydraulic' and High Load-Rate Valve Springs, * Edelbrock Aluminum Dual-Plane High Rise Intake * Holley 600 CFM Carburetor.
