balancer slipped?????
I have 75 b200 / 318. this is my first dodge, I just installed a 4-barrel air-gap and a 625 carter afb in place of stock 2-barrel, when I went to time it I could'nt find the mark's. I went underneath, used white out to mark the balancer, hooked up the light and it was no where to be found. so I timed it by ear. it runs great. a little hard to start because the timing's off. could the balaner have slipped or did the timing jump?????

I'm not sure, I think some of the vans had the timing TAB bolted on in a different spot. (on the passenger side). I would also "now swear" that some vans had the timing back through a slot/ hole in the bellhousing. But it's easy to check
Find, get, build, or buy a "piston stop" like this:

Remove the no1 plug, make sure the piston is "down a ways", remove the battery ground for safety, and install the stop
Gently wrench the engine around until it "stops on the stop." You may have to adjust a first time setup. Matters not WHERE is stops, but you DO want the piston down somewhat, because----as the piston gets closer and closer to the top, it slows down past TDC, and this reduces accuracy of the test.
So with the piston against the stop, make a temporary mark under TDC on your timing tab.
Rotate the engine CCW until it stops again, and make a second mark. True TDC will be halfway between the two temporary marks, and if the factory mark is accurate, that is where it will be.

If your thinking about a cam gear drive, know that they can be noisy. My buddy has one in a big cam engine and with mufflers it sounds like a blower, very annoying.

There's no reason to run a gear drive on a mild street engine, and they may not even be as reliable. Just buy a good quality (like Cloyes) "all steel" setup, no phenolic top sprocket.
