Can't you just here Austin Coil saying, "hay pass me the two dizzies and we can fire this thing" or is this one of those Hottroders terms, dumbing it down, like Hotrodders terms for dummies kind of thing.

Maybe a pole here..
21st century wrench'n "Ebonics"

(probably used more on the internet than in regular conversation between two knuckle-draggers - - er uh, i mean mechanics )

But I pointed out he didīnt have to use if he didīnt want too in post #3.
If his block aint chamfered he has no option.
I just plonked my MSD in today, sans O rings, and the fit was perrrfecto.

The lube packet provided by MSD had pooped over the Atlantic so Im using
pre lube.

Hey Pepi......its hear not here....maybe the term dizzy is just as lame as your inability to use the correct word in the correct context

Without 'O' rings (stock distributors primarily do not have the 'O' rings), some oil can get by the O.D. of the lower distributor body and the I.D. of the block. If this clearance is excessive, then the oiling to the passenger side of the block will be lessened. The 'O' rings tend to 'seal' off the clearances.

This has some pictures of a ring&pinion install with wear pattern shown. On a distrbutor gear you really only set the depth unless you use a front thrust button or (OEMretainer plate)(roller cam) and the rear cam plug or a stop for backlash. Flat tappet lobes have a taper that keep pushing the cam rearward toward the gear.

ScoTFrenzel dizzy, noss, donk, bubble, hopper, zip, etc.
a lot of new buzz words created by the younger generation to sound cool.

Didn't you see the modern classic, Fast and Furious?
It will be (IS) their American Grafitti and Two Lane Blacktop.

Sort of like hot rod, rod, deuce, highboy, lead sled, etc.

XNTRCI-T If your question is why is it necessary to chamfer the block, it's so you can get the distributor into the block with the o-rings in place. Without the chamfer, the o-rings get bound up and cut by the sharp edge of the block.

I have an MSD which I hoped to install today, but one thing is bothering me,
the flag on the distributor gear.
I have 15 - 40 Castrol in mine and donīt fancy oil changes for installing distributors.

I wonder - what is the healthy wear pattern on a distributor's gear supposed to look like?

BBCMudbogger I actually picked it up here too....lol....too lazy to type distributor all of the time......I guess the question is why would you go out of your way to chamfer the distributor holes in the block just to run the o-rings and if the block was chamfered and you didnt use the o-rings what would happen and if there is any advantage to either?
