Looking for some info on CAM install
Soooo... I am wondering if there is a write up anywhere on cam installs on these 4.7s. I havent had the luxury of swapping cams in a "newer" vehicle and am wondering what I am looking at when I get cams.
anyone have any ideas as to what is needed before tearing the valve covers off, and the subsequent work there after? (lets pretend I am going with the HO cams.)

Eric, I looked at the guide above and that is one of the best I've seen. When I installed mine I used the KRC guide below and Hayne's manual. If you don't have a wedge tool, no big deal I made mine out of wood. I used a pipe wrench to return the cams to the neutral position after installing the new cams. Just make sure your rockers are all good to go, I had one that turned and I didn't catch it until final inspection and was lucky to fix it before putting the valve cover back on.

Yep, its about three hours or so. I did not use the spanner wrench though, I used a pipe wrench. The cams at TOC are 15 degrees from the neutral position. You will know it once you loosed the bolts on the camshaft bearing caps as the cam will move. Once the new cam is bolted in and torqued to spec, I used a pipe wrench to turn the cams the 15 degrees back to neutral and then put the cam sprocket back on. You don’t’ have to use a spanner wrench, but it certainly won't hurt.
