EBAY DISTRIBUTOR - Turn over pop
"HOW TO" install a distributor:
As mentioned above if there is ANY question of timing marks, use a piston stop to verify them
With that done there are only two ways to verify no1 is on compression, "ready to fire."
1....If either valve cover is off, and timing marks are at TDC, look at either no1 or no6 valves. They will either be both closed, or both pretty much evenly open. Rotate the engine a small amount and see if they move. If not, that cylinder is on compression
2.....Otherwise, remove no1 plug, stick your finger in the hold and bump around, feel for start of compression. When you feel it, look at the marks, they will be "coming up."
Do NOT set the marks on TDC but rather where it is that you want timing, IE 20 BTC, etc
Now drop in the dist as close as the rotor will come to same as the old one. As mentioned above, some are not indexed the same DOES NOT MATTER
Rotate the dist. body so it sits "where you want" so far as wiring, vacuum can, etc
Note which cap tower the rotor is "coming to" (remember B/ RB rotates CCW) and use that as the no1 plug wire
Retard the dist body (ccw on big block) and slowly bring it advanced (cw) until the trigger device appears "made."
YOU CAN ALSO power up the ignition, and move the dist body back and forth to trigger a spark. Move less and less, slower and slower, until you find the trigger point and leave it. OR crank the engine, set the timing "on the starter" with a light
Start it up
