It'll be just a bit choppier and sound more aggressive and (more importantly) with a short stroke motor like a 383 it'll kick in a bit quicker and harder so the roll-on power (upper bottom through mid range) will be quicker. The standard off the shelf 271HDP is cut on a 112 and in at 107, this cam on the 108 spread 105ICL just works really nice in 383's and 400's. On 112 it's an awesome stock replacement cam for a 440 Six pack or 440 with bolt-ons. Crower Hydraulic lobes just always work great in mopars from my experience.
