Odd Distributor Question - ??? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

TonyJohnson · 04-18-2008, 01:26 AM

I know the trick of marking the rotor position and the vac pot position for easily replacing a distributor, but I'm getting ready to install one that doesn't have a vac advance. Does the distributor position (other than the rotor) matter? Should there be a mark for number one on the new distributor?

For background info... I replacing a coil in cap HEI with a skip white small cap dizzy (8930R) that only works with external coil and external ignition box (MSD 6A in my case)

I'm guessing that as long as I pick a terminal for #1 and orient the other wires from that I'll be fine, but thought I'd do a sanity check before starting...

Here's a link to the distributor...

The position of your distributor housing does matter, that is what sets your ignition timimg. note the position of your rotor and pick the cap position closest to your fire wall and mark it. when you put it back your timing should be very close. but still put a timimg light on it to get exact.

What matters is the relationship between the rotor and the tower you decide is #1. You could turn the thing 180 degrees and just pick another tower as #1 and wire from there - so you're absolutely right.

Label #1 though so someone else doesn't have to figure out the wierd thing you did
