Have a few ?s on my sbc400

[Displaced_Txn]

Have the sbc 400 in my 77 k5 blazer and there are a few lines blocked off or missing. Just wondering if anyone had a vaccum diagram they could post up or send me. I do know for a fact the vaccum advance isnt hooked up currently and has the three ports for the tvs? on the thermostat housing.
Just one of the small things i need to get done before It can pass inspection.

Look at Section 6E - Engine Emission Controls in the 1977 Service Manual beginning on page 6E-7 (Pg 651) for the 400 vacuum diagrams.
