Cam question

[John Ratliff]

Can some of the members on here give me an answer to the question,what is a "RV Cam"? How is it different from stock?
Thanks.

An RV cam is profiled to give better torque at lower rpm's so it can pull the weight with less engine and transmission stress. Truck cams are similar if not the same thing. These cams are not efficient at all for most driving styles unless you have a "tow package" installed by the factory which is normally nothing more than a different rear axle ratio, heavy-duty cooling system or additional transmission and oil coolers and pre-wired connections for the trailer wiring circuit.

RV cam usually has slightly greater lift and slightly faster action with the slightly greater duration as the OEM cam. Seldom-to-never worth the money.

It's for those who want to feel like they've built a hot rod, but don't want to lose low end torque or fuel ecomomy.

FWIW, the same effect could be produced by increasing rocker arm ratio.

I think it is a mute point, because you are not likely to find a Studebaker RV Cam! [:0]

Actually, any cam grinder can re-grind an OEM Stude cam to his "RV grind". Again, "RV cam" is just tire-kicker jargon, like "3/4 cam" a way to provide a non-technical indication of the general characteristics of a camshaft.
