you will have to take the whole front end of the truck apart, take the timing cover off, remove the rocker arms, remove the push rods, take the injection pump off, remove tappet cover, install 1/2" wooden dowels in the lifters and secure them in the up pos, remove cam retainer, pull the cam out, install tray to catch lifters if they fall, press the cam gear off, heat cam gear up and install it on the new cam, bolt the retainer on, drop the lifters into a tray not into the oil pan ( if you wanna change them), install new lifters ( time to go fishing 5 and 6 are a pain), remove tray, install the cam after its all lubed up,reinstall pushrods, tappet cover, ect

yep, just make sure to line the 00 and 0's up before you remove it, that way you put it back in the same way it came out
