I found this info while searching around the net for cam specs for my upcoming cam install. Thought that some of you might find this info interesting if you are looking at some hard numbers about different cams, I know I sure did. Interesting to see that the 260, 268 and 273 are all pretty comparable until you get above 5500 rpm. The four pulls were done on an engine dyno with the only other mod being a set of LT’s.

 

Here are some graphs to make it easier to compare the four cams.

 

nice info. i was looking at the 260...

 

It really makes it clear that the 260 is the best choice for a daily driver.

 

That is what I thought too. Unless you are really racing your truck you are not going to see any benefit from going with the 268 or 273. That is why I am going with a grind off of the comp 260.

 

so a 260 would be good for a daily driver

 

The 260 actually seems to be the best IMO. It makes more TQ than the 273, and more HP than the 273 up until 5,000rpm's. I mean, how many times do we really go above 5,000rpm's ? I am really liking the numbers on the 260 a lot. When you do a cam swap, is there anything else involved with it? such as lifters, springs, etc???

 

Yes. Check out the torque curve in the 260, that is what you need to get your heavy qc 4x4 moving. That is one of the reasons I am going with a 260ish grind.

 

I would love to see a dynosheet of someone with a comp 260 and 4.56's.

 

great info teach! i'm waiting till more of you guys do the install so i have someone to direct my questions to.. then maybe, just maybe
