Re: Correct Timing Marks 240 & 300

If you are facing the front of the balancer with the keyway at the top the timing mark should be just to your right about an inch roughly. On older models it will be a notch and later models a thin line if I remember correctly.

Re: 1984 300 won't run

hook your voltmeter to the purple and orange leads out of the distributor and crank over, it should generate aprox .5 volt. If it does then distributor is working. In that case if wiring between dist and module is good I would substitute a known good module.

Yes they made both after 1970. Pump mount bell housings have 8 bolts and case mount has 5 bolts, I personally have had no problems with either. However beware that you don’t get a C5, they had a lockup converter that gave lots of problems. The converter and bellhousing a roughly about an inch deeper.

Is the cat converter still on - if the carb was flooding it could have melted the catalyst stopping the exhaust mostly up. It is simple to drop the exhaust pipe loose from the exhaust manifold to test drive - if it runs good then you know where to go.
