Topic: Has anyone changed to a different camshaft?

[andpgud]

Hehe. Sorry for being a pain in the ass. Will search for this.
I need 4 of every part?
The ones you gave up, are they going to perform well together?
I try to find any info on the lifter fx and there is nothing said about it. Is it better than the stock one?

this is for the lifters and pushrods:
you need 8 of each (you have 8 valves)
the lifters are stock, you don't need anything fancy since you are not going to spin the engine over 5500rpm (there are fast bleeding lifters for high rpm engines to prevent valve float, you don't need that) and the pushrods are just regular ones with stock length, same here unless you run high rate springs you don't need anything fancy, if you want to get something better comp cams has heat treated pushrods but they are pricey compared to these ones.

what's the lifter fx? not sure and didn't see that mentioned anywhere in this thread (could have missed it) if you had read this on another forum post a link so we can understand what you're referring to. but then again, you don't need a different lifter the sealed power or clevite ones will work just fine.

So if I am not upgrading, what is the sense of changing since I am not having any problems with my engine? Or are you just saying I should do this since I am doing the cam.

• The cam has been on another car. Nothing wronk with it. Does that change anything? Are the lifters supposed to come with the cam?
  

get new lifters, still use breakin oil though just to be safe.

Last question. How manu springs and retainers? Also 8?
This will then be handed over to my mechanic :P
I need 8 valve lifters and pushrods.

[andpgud]

I used Mopar Performance valve springs and retainers meant for a Magnum v8, no machining required:
Springs: p5249464
Retainers: 94529216

I found all the parts on summitracing but the retainers. What model and year should I be looking at?

Do you have any videso of your cars running with different cams?

Yes...  2 valves per cylinder means sets of 8.
