Probably be cheaper to just take it into a shop and get
it done for you. If you follow the GM service manuals
instructions on how to manually install and set the dist,
you should be right on the money. I've never had a problem
with the cam offset when following the procedure.
No, the Tech 2 is not necessary to bring it into phase. If
you follow the instructions on how to install the dist
properly, 99 times out of 100, you will be right where
you should be. The one other time....yeah....you might
want to hook up the Tech 2...see where you are at, and
then move the distributor slightly to bring it back into
phase. The dist has a mark on it.....line the engine up
tdc #1, line up the rotor to the mark...done.
I think I've had to use the Tech 2 to do this procedure
maybe 2 times in the ten years that this engine has been
out. And I've done "tons" of engine work on the small
block and v-6 engines.
And can you really trust that some guy posting on the
internet has any clue what he's doing and has actually
either read the service manual information and interpreted
it correctly and managed to install the dist correctly? I
