Purple Shaft 280/280 cam

Streetability really boils down to tuning and what a person likes.I know of several people inlcuding my brother that run cams with around 5in. of vaccum at idle and they perform excellent on the street,we make a cruise to the beach (2hr. drive) every year and its done great for the last five years and knocks down 16mpg.The right initial with a good hot ignition system,good cooling system and the correct carb cfm/settings will do wonders for a nasty cam.Im not saying these cams are ideal but no ones going to lose double digit horsepower going from one grind to another with similar .050 timing events,so its what you desire in a camshaft.Just make sure you have enough compression,cubes and stall/gear to support it when looking at different grinds because thats how you want to pick your duration at .050,lobe seperation is really secondary and can be used to pick the cams idle characteristics and where the powerband/sweet spot is for the duration.
