Depends on how radical a cam you want to go.

 

If you go big, like the 268, swap the MD's lifters out. For tuning purposes I'd lean more towards the 05/06 pcm then if you also score the tcm you can do a custom tuned pcm and tcm and make it into a rocket

 

The comp 268 was about as crazy as i was planning on going with the cam

 

Alright I'll look into doin the lifters while im in there. Shouldn't be to much extra work or cash i don't think.

And thanks for the advice on gettin the tcm as well. I didn't know that had anything to do with the tuning. After all a "rocket" is kinda what I was hoping to get outta this swap!! Lol

 

I ll be the first to say I dont know jack about camshafts...lol..What I can say is I ihave a 2005 ram 1500 with a HEMI in it. And as I was reading what you all were saying I like the idea of doing a cam. So here are my questions to you all. Q#1 Where are some links to some different camshafts ? Q#2 Can you just buy a cam and pu tit in and notice a difference, or do you have ot buy other parts, do programming, and 1000 other things along with it ?

Thanks

 

From the researching I've been doing I've found that you don't have to change many other parts. I know that it's recommended to swap out the valve springs using 6.1 hemi exhaust springs for all 16. As well I've seen that its been recommended to swap the pushrods for the 6.1s as well. And as far as other parts go I think those were about the only ones you should change when doing the cam.

As far a tune goes I think most cams need some sort of a custom tune. I think some of the smaller cams (like the comp 260) can be tuned with just a superchip and don't need custom tuning. If you go with a bit more aggressive cam such as the comp 268 then you will need to get a custom time to make it run right.

Some the other guys here that have actually done there cam swaps might be able to give you some more info on the subject as I'm still just learning myself and this is just info I've gathered from my research.

 

Bare minimum you need to do the 6.1 springs and push rods, the rest depends on the cam you pick.

Some cams just need the springs/push rods and a normal canned tune (superchips or dsp) others need much more (custom tune, gears and a stall) in order to get you into the powerband of the cam. Look at the rpm range for the cam and some dyno sheets to see where the cam builds up and falls and plan your mods accordingly.

As to where to buy, Comp Cams, Inertia Motor Sports are a couple, do a google search and you will find quite a few more. Go to different forums and ask around what people are running, what they have ran and what worked the best for them.

 

i have a 2006 with the hemi, i just ordered the 268 cam for mine, should i go ahead and upgrade my springs with it?? i already purchased the custom tune and need to know about the springs.

 

My 268 just came in today . I will be installing it this weekend. Yes you do NEED new springs and pushrods. Here is a link to the springs, at the bottom you will see a picture of the push rods. http://www.moparsupercenter.com/6-1l...5037477ac.html

Question goes to weedahoe and or truckn, what oil can I use to break in the cam?
