Check your distributor connections. If this has the large weatherpak connector coming out of it towards the passenger side, then it is early computer timing control. I have had several of these, all 86 305's in p/u's, come into the shop for tune up. Also, look on the passenger side of the block behind the starter for a knock sensor. If you have these two things, I would be willing to bet that your timing control in the computer has gone south. The begger will chug right down, have no power, and sound like a couple plug wires are off, as well as start crappy and begin to run hor. The early computer is goofing up and whacking a huge chunk of timing out of it. It's an easy fix, just swap in a distributor from a SBC a couple of years older, and on the power wire to the distrtibutor, unplug the lead going over to the harness leading to the pass. firewall. Then plug in the single lead you have left. Re-set timing as normal.
