Broke my car at the track today...
yep, seriously...
Second pass of the day.

So here's my tech question:
The gear on the end of the distributor. If you look at it, and where the roll pin presses through the gear and shaft. With regards to the location of the rotor, How is it oriented? I need to put in a new roll pin and want to make sure its in correctly.
Before I confuse anyone, if you look at where the pin goes in. On one side, it lines up with one of the teeth of the gear... But on the other side, it lines up between two teeth.
Looking at one side, I need to know which direction the rotor is facing. So I can re-align mine.

the holes are often never centered upon drilling so , I've found that to get the gear to line up with the holes it only fits on in one way to get the pin to tap back in place...... what did it run on the first pass?? et/mph

The booth couldn't find my ticket when I got there (thats my story, and im sticking to it)

Yeah, it shouldn't matter. Once the gear is back on if it's pinned through whichever hole and off slightly, just adjust the dizzy to get the timing back.
What happened, did the gear on the dizzy just grenade?

Its a fairly safe assumption that the pin didnt just "go bad" and likely that its been breaking little by little for a while. With that in mind, the car ran like crap for the first pass.

HV pump won't matter at high rpm. Gear load is dictated by pump pressure, which is just resistance to flow. At high rpm with an HV pump the bypass is already open and pressure should only top out at around stock 60-65psi. They do load the gears more at lower rpm when cruising since the pressure is higher at low rpm relative to a standard volume pump(hasn't kicked the bypass open, but still flowing more volume, so more pressure), but not enough to break them.
I've been running a standard 65psi HV in mine for years in my daily driver that regularly sees 6,500rpm, and the dizzy and cam gear show hardly any wear.

I agree, pressure wastes power.
As for the pin. If it will go in both ways. You can question it but I've always found they will only fit one way.
Even if it does go both ways. It will only index the rotor off a few degrees and you will easily get that back when you move the distrubutor housing to adjust your ignition timing.

haha sux man. i went up on saturday. and ran the Street Ford class. Made it to the 3rd round of eliminations. somehow i missed 4th?!? on the last run..
it ran a best of 13.024 @ 105.8mph but with a crap 1.914 60'.... i need better tires than those stupid Nitto drag radials i have.. so close to 12s n/a!!
