Yes, you could pull the coil wire and bump the ignition around while someone watches for the TDC mark, Realize your fuel pump will still be pumping lots of fuel into your carb while you do this so don't plan on starting it anytime soon. Also have a strong battery or a charger connected to it to keep from draining it. Alternately you could move the flywheel by hand. You have to take 6 bolts off the bellhousing dust cover on the bottom and put a rag on it and pull it around by hand or with a tool designed to grab the teeth. Make sure the parking brake is on, you have the wheels chocked and the transmission in NEUTRAL. Trying to do this in gear is going to make the truck roll ...if your brutishly strong. Not good! Removing the spark plugs will aid in removing some compression and making this easier, but it's doable w/out removing the plugs. Also if you do this you can make a mark on the 6 oclock position on the flywheel once you have it on TDC, that way when you move it around again and if you are by yourself you will be able to get it pretty close to the mark again by looking at the 6 oclock mark while under the truck.the question I have about the valve adjustment. Put the pointer on the flywheel to the line (TDC). if its on the compression stroke the rotor of the distributor should be pointing to the #1 spark plug wire at the distributor? Adjust 1,2,3,5,7,9. Then rotate the engine 360 Degrees stop at the TDC line again. Where should my rotor be pointing then so I know I am on the exhaust stroke? Then adjust 4,6,8,10,11,12. and how do I turn the motor over manually by the fly wheel? unhook the Coil so it doesn't fire.
The rotor will point away from the motor instead of between the 3rd and 4th plugs if you are putting it on the exhaust stroke. I like this guide for doing the valves:
