how to tell if the distributor drive gear is installed correctly?

Have been chasing my tail on my 69 Barracuda, 318, auto, have posted other questions. Last installed was a Pertronix Distributor with there Ignitor II module and there correct coil, [ no resistor, full power to the coil and dist, per there directions] with that I was able to have car start, but ran horribly and would just keep getting worst till it would shut off, pull plugs some showed that some where not firing, some had carbon, #8 was covered with gas after about 30 sec. run time.

Gave up on the Pertronix unit {after replacing the unit in the dist. also}.

Read on here about Ricks Mopar, I am trying one of his Mopar style dist. and ecu unit. Followed his instructions, had the engine timing on 10deg. before , as per the Instructions, marked #1 rotor was pointing . My question is at this point, the rotor for #1 is almost facing the fire wall, everything I read it should be front/left front, anyway now I seem not to have spark, when I crank the engine wants to jam?, tried to play with the timing a little advanced/retard but stays the same, just to review I had in a cheap Pro Comp dist. and there coil, the ran for about 3 years, then over last winter I had a battery tender hooked the battery over the winter,[ had cables hooked up , my error] which seemed like it took out my electronic voltage reg. [ have updated to a dual field alt. and wiring for the electronic reg] ,which I was sure caused the coil and the dist. to fail, car would run but had to give it gas to keep it going at a stop sign, till by the end of last year it stopped running. I had my friend help me, when I installed the Pertronix unit, [ dist. and matching coil], got the timing mark to tdc, and again the #1 on the rotor was toward the fire wall, as stated I have about 500 miles on the engine since a total rebuild by a local Mopar person. I am questioning could the gear that drives the dist. be off??

Have ruled out a carb/fuel problem, [ new Holley carb, old known good carb] check for poor connections/corrosion, have correct voltage to coil and the new resistor , ignition switch was checked no problem. [ as stated car would fire right up with Pertronix unit ] have pulled the spark plugs did compression test 150-155 on all cylinders. I just me seems like some type of timing issue, that is why I ask about the dist, drive gear, engine has only 500 miles, a new timing gear, chain was installed and the engine ran [ again after total rebuild, bearings, Keith Black 167 pistons, 30 over, Comp Cam, heads redone, new harmnic bal.] for 500 miles.
