Wbain is correct, start with the basics. You said it idled for a short time when the carbs. were primed. You never said if this is the dual overhead cam 6 with a single 4 bbl. carb. (on the driver's side), or the single overhead cam 6 with two 2 bbl. carbs (on the passenger side). Since it sounds like you've already replaced all the fuel lines, the fuel pump (both are on the driver's sides) may be bad, or a bad fuel filter, if installed. The pumps are rebuildable and also available rebuilt for a fairly reasonable cost. You can check for fuel by disconnecting the fuel line at the carb(s) (if the two 2 bbl. do just one) and direct the line into a small can or bottle. (As I recall this is easier with the 4 bbl. <rubber hose> than with the two 2 bbl. <metal lines> setup.) Have someone crank the engine for a short time and see if fuel starts flowing into the container. It should pulse with a fairly good squirt on each pulse. IMPORTANT: Although there should be no ignition source near the carb(s) on either engine, you should still exercise extreme caution not to spill any fuel. If you're getting fuel (you should get about 1/2-3/4 cup in about 15 seconds) I would start looking at the carb(s). The fuel, if any, in the container should smell "fresh" and not smell like varnish. The carb(s) could possibly have bad varnishy fuel, water, corrosion, or float issues, just to ID a few potential problems. No matter which carb(s) you have, the tops can be removed easily while still on the vehicle and inspected for proper integrity. If you get to this point, let us know BEFORE you begin this action. Hope this helps.
If the vehicle has been sitting for a long time, you very well may eventually have to check the carbs. I think you said you drained the tank. What was the fuel like in it?
