So my son has a 2011 charger 5.7 ex police car. I want to replace the lifters as I know they are most likely getting ready to fail I figure at that point may as well slide a cam in it. This car was well taken care of I know the cop that drove it from a small beach town near me it was well maintained has 90K miles on it. What is a decent cam that is still somewhat manageable to tune? I plan to delete the MDS and I know I will have to limit the VVT. The car has the 308 gear option as well. I would like to get this thing in the 12s it has run low 13s already.

I did the cam swap in my wife's durango r/t per Dave's recommendation. I had the heads off and for 270 bucks for cam and springs I figured why not. It is a pretty good boost. In my opinion it needs a tune to take full advantage of it. Have about 6k miles on the swap. No issues so far!

Are you guys degreeing these new cams or just aligning the dots? HRD, how much lift and duration are they different?

Cab, I just lined up the dots per what a friend of mine told me to do. It runs really good. I have heard some have degreed them in and they did not run as good? If its good from the factory I figured it was good enough for me
Thank you Kiddart

The computer degrees it in real time. I am curious how people are "degreeing" these cams unless they lock down the phaser (dumb idea). I didn't realize it was a VVT engine. So how do you verify that the camshaft and the ECM agree where the ICL etc is? Kevin

HotRodDave, that spring info you gave is wrong. The 6.4 installed height is taller than the 5.7. A 6.4 spring CB is around 1.4. When installed at a 1.98 in an Eagle head you would be right on CB with a 6.4 cam.
Another thing, the 5.7s springs CB measurements are all over the place. From 1.30 to 1.37. However, the stock mopar springs have really stout pressures.

I just went out to measure an eagle head. No shim I got 2.015. It came with .040 shim. I have a few .080 shims on the peg board so they must have made a change somewhere. Anyway 2.015-.570=1.445. So I really don't see how you can run a 6.4 spring safely at all
Also CB on the one spring out of this eagle head i just checked was 1.39

I have 6.4 springs on my eagle heads with an SRT8 cam and it runs great, no coil bind and this is not the first one by any means. I could see daylight between every coil with the lifter bled down then shimmed solid with feeler gauges. Theoretical and actual are frequently different. I have 2 .040 shims in there, 3 and I could barely see light through a couple of the coils. Your saying you have .080 shim with springs that came out of 6.4 heads? And cam lift is .571 correct?
