224 in LS1 Truck
the install is pretty simple. you just have to be careful when taking the bolt out of the oil pump tube if you decide to swap out the timing chain...you'll also have to lower the oil pan to do this. i recommend taking the front cover off the pump and pulling the 2 gears out to make it easier.
other than that, the next tricky thing is holding the lifters up when you pull the cam. 1/4" pen magnets work well, otherwise you can use some 5/16" dowel rod and slide it into the 2 holes in the block next to the cam retainer plate...ive never done it that way so i dont really know how it works.
if you do a google or yahoo search, you can find writeup on doing cam swaps. it will be nearly the same as doing it on a fbody....atleast all the internal engine stuff will be the same.
