Of course a dealer can't "help you"; all they know is, how it came from GM. That's not in their contract. Even if they knew anything else, they couldn't tell you anyway, because GM forbids them from doing so.
If you have a late-model roller block, all you have to do is get the retainer plate and screws from GM (or out of a junk block). Be aware though, there are 2 different plates, with different screw hole spacings, to fit different blocks. Just one more way the factory porked the pooch on their "system".
Yes the oil pump sucks the cam into the block, by way of loading the distributor gear, which loads the cam along its axis.
The sprocket on the cam IS NOT pressed on; it bolts on with 3 bolts.
The sprocket on the crank IS pressed on; it requires a puller to remove, and can be put on either by pressing, or by the gentle use of a BFH and a brass drift.
This 3100TB thrust bearing is for blocks without the factory roller setup, although it looks like it would work in roller blocks as well. It bolts on the block, behind the cam sprocket. Note on the Comp catalog page that it says "minor machining required". This refers to drilling the holes for the 2 little screws, and machining out a bore in the back of the cam sprocket to accept it. The bearing is .142" thick, so I would guess, not having read the instructions, that the cam sprocket would want to be bored to about .135" or so deep to accept it (enough that the sprocket itself was held just a couple of .001"s off of the block by the bearing). Usually when I use these I just buy the timing set with the bearing already included.
Not sure what this has to do with the melonized distributor gear?
Not sure how this thread is "official"?
