Hi guys, I have a 1988 c2500 Scottsdale that is completely stock, the only thing done to it is it's straight pipped and has headers. I've been doing research on putting a cam in it but I don't really want a lot of power, just a little more umph for pull a horse trailer. I looked online and can't really figure it out on my own because I'm new to camming, I was looking at putting a comp cams 268h flat tappet in it because I do want a slightly choppy idle but I don't know if it will work with stock internals, if it won't work can you guys give me some suggestions, I don't really have the money for new heads or anything so any advice is appreciated, thanks in advance
