You still don't get it...
And I don't have graphics to show you how it misaligns...
There is a SINGLE pin on a distributor gear,
That pin is NEVER drilled directly center of the gear tooth pattern.
So when you get the gear on backwards, you split teeth and you are AT LEAST 1/2 tooth off in rotor phasing.
Now, there are still guys that don't get rotor phasing, swear it doesn't exist since THEY have never heard of it before...
Although about every serious ignition company addresses it,
Distributor gears are marked with a 'Front' or rotor nose location to get them in the shaft correctly,
So just because some guy can't get his mind around it doesn't mean it 'Doesn't' exist...
I really don't care *IF* you believe it or not,
Not my call to educate the peanut gallery.
I'm here to help out the OP, and other than that, it's all just white noise...
I recently suffered from this issue. The crank was installed with top dead center in the number one cylinder (unfortunately on the exhaust stroke and not the compression stroke). The cam gear was then installed onto the cam with the marks aligning as stated earlier. Crank gear mark at 12 and the cam gear mark at 6. I ran the truck this way for 1000 miles. recently I decided to add a crankshaft/harmonic dampener pointer to get more accurate distributor timing. I removed all the accessories on the front of the motor and the number one plug. I then removed the top cover (two piece) to the timing chain. Next I rotated the engine until the number one cylinder began pushing air out of the spark plug hole, rotating until the air stopped coming out of the plug hole (verifying TDC compression stroke). I then slipped on the harmonic dampener to determine TDC, the pointer was then adjusted to align with the TDC mark of the dampener. The problem that was noticed was the timing gear mark was at 12 and the crank gear mark was at 12. Cam gear was off by 180 degrees. I then removed the lifters and pushrods, and the cam gear and chain. The cam gear was then reinstalled without the chain and rotated 180 degrees (so that marks on cam gear 6 and crank gear 12 were properly aligned). Thus one can see that the cam gear can be off 180 degrees from the crank gear, with the distributor installed properly (at number 0ne on TDC) the truck will operate but not as great as it should.
To the hijacker, you are Way over thinking this. The cam and crank gears only go in one way, with the dots lined up. You then turn the engine until the cam gear dot is about 1:00 and count the links to verify.
This install puts #1 cylinder at TDC "exhaust". It has no bearing on setting the distributor. You can rotate the engine until #1 comes back up to compression to install the distributor.
