273 Camshaft Specifications

hi, back then , they had wide lobe centers, which shortens up overlap. take same cam and put it on 108 lobe centers , its a different cam then. the 235 /273 cam has a very fast ramp on it. actually it is a good grind!! we had the 235 cam ground on 108, centers, put it in a poly 318, dual four engine in a 57 Plymouth, it was very torque. could spin tires very easily.
