Which MSD Distibutor to get?

[ZookBronc]

I am running a late model 5.0 with a hydraulic roller cam, carburator, MSD 6a ignition box. And do i care if its a vacuum or mechanical advance? I have a vacuum advance now. I think it needs to have a steel gear on the distributor but which one do i get?

I wanted a vacuum advance on mine, so I run a 8479 MSD distributor with a 6AL box, and yes you will need to have a steel gear pressed on. If you are not in a huge rush call MSD as they will press on the gear for you for just a few bucks.

Then if anything ever happens, they can't ever say the gear was installed wrong

They also have
Ford 302/289 with Steel Gear for Hydraulic Rollers PN 8598
But that one has no Vacuum advance

Go with the vacuum advance. It helps part throttle power and economy. Only full race versions should go with strictly mechanical advance.

Mine is mech advance.Why should mech advance be used for race only?

You don't need vacuum advance, but it does help with fuel economy, and now adays any little bit sure does help
