I don't know much about cams, but that sounds like a very mild cam. I wouldn't think you'd notice much of anything from it. If I didn't know any better I'd think that was what the factory cam specs were like.

Re: Power increase with RV cam and roller lifter

If you are going to go that route, then you are probably going to want a machine shop to do a performance valve job on you cylinder heads also. Just had this done to my truck. Fresh 355 with RV cam (Same one you are getting), and the heads done... All I can say is the torque is there! Its no contest for most things that require some pulling. Just remember, you are making an already torquey engine even torqueyer... In other words, dont expect to win any races with it. You improve your lower end torque, but your R's dont do so much once they break the engines 'comfort zone'... say between 1800 and 2600 RPMs.

So yes to that cam if you wanna rip a house off of its foundation, but no if you just wanna blow the doors off of the neighbors camaro.
