Installing dist. - did I do it right?

I am putting a 401 into my CJ. I have the engine back from the rebuilder's shop. He told me it was sitting on TDC #1, ready to drop in the distributor. The engine had a pretolite dist. I got a motorcraft from the PnS out of an 80's waggonneer. Looking inside the dist, there is a "tanged" wheel; the 8 tangs rotate past a pickup coil looking thing. I dropped in the distributor, rotated the body of it a little so that one of the tangs was lined up exactly on the pickup coil looking thing. Put the cap on and checked to make sure the rotor was hitting right on one of the cap posts, which it was. This post is now my #1 cylinder; marked it with a sharpie [img]images/graemlins/grin.gif[/img]

Question is did I do it right? the #1 marked post stamped into the cap is not my #1 post, but it should be ok; the distributor doesn't care which post is #1, right? And does the thing rotate CW or CCW, so I can figure out which one will be #2.

thanks

Yup. You made sure the distributor engages the oil pum too, right?

You do know the firing order, right? 1-8-4-3-6-5-7-2

You did it right.

Sorry, I don't know which way it turns on a 304. I've never had one, and don't know if other motors do it differently. You could always simply turn the crank clockwise and see which way it turns.

If need be, it's easy to find #1 tdc again. Just crank the motor over (w/o any spark plugs) until you pop a rag, cork or your finger out of #1 spark plug hole, then rotate the crank further by hand until the timing mark on the front balancer shows tdc (or zero advance).

I think your only issue will be whether the distributor is indexed properly so that under all conditions of advance, the rotor and contact are in alignment. Dont' forget that the rotor advances as well from the mechanical and vacuum advance mechanisms.

You may want to find a new drive gear for the dist. I have heard these older gears don't play well with new gears. Unless your builder used your old gear on the cam, then you might want to use the old gear on your original dist...
Anyone else want to confirm this before he does this??
