I saw that there were a few old posts where people asked about rv cams for 20r rebuilds. are they talking about the cams out of the old dolphine yota campers? if so, what gains do you end up getting from them? thanks

 

An RV cam makes most of its power in the lower rpm range, thats why a lot of people that are into rock crawling want a cam like that. If your truck was used more on the highway then you would want a cam that has more power in the mid range around 2000 to 3500 rpm`s.
