Does anybody know what lift, duration, & lsa specs are on a stock 6.4 cam part number 05045517AC

The Bad:

I personally wouldn't do it unless maybe the cam was free.
You would have better results with performance cam for the 5.7

Just found your video, is that the cam I am questioning here? would you recommend it?

 

[burner71]

i think the one your looking at is the car cam.
Mine is the truck cam.
I would only if you planned to have it tuned. It runs pretty ragged on the stock tune.
You also need to upgrade your lifters.
If camming is your only upgrade for power I would look to other options.
I used this cam only because i plan to supercharge

this is supposed to be the truck cam(J code engine), I would definently get a custom tune and do lifters and springs, did it make a big difference? I'm either doing a cam or nitrious just haven't totally made my mind up

the difference at 2800rpm and up is night and day. Tons more power in the upper band.
