Thanks, SilverMiner...

I already have my mind set on getting an intake manifold with EGR port, an EGR and any other necessary components, although tedious it must be done if I want to drive it, which I do.

I don't see any signs that my Blazer had an A.I.R. pump on it other than the folded over exhaust smog pump tubes, although my Blazer was/is not a California vehicle. I believe the exhaust manifolds were replacements put in at the the block was replaced. I don't need the smog set up. It looks like you have the same set up as in the 2nd diagram I posted. Thanks for the info! It is much appreciated.

IF anyone has all the vacuum lines in use any pics would be much appreciated.
