Distributor Position In Rebuilt 289

On a rebuilt 289, if the #1 piston is at TDC can the distributor be installed at any position? My distributor slipped in at 4 o'clock. I followed the firing order with the plug wires. Engine wont start. I wanted to ask before I start messing with it.
Thanks

Technically yes, but a weird location could cause problems when you try to route your plug wires. You might be 180deg off now, which would keep it from starting. I would just start over and get it 'right'.

+1, but, to answer your question...... Theoretically, You can drop your distributor in any position, as long as you have clearance. The only thing that changes, is the terminal designation on the cap, for #1! When at TDC, of #1 cylinder, Whichever terminal on the cap, your rotors pointing at, has become your #1 , and you'll have to start your firing order, from there. But as mentioned before, you could still be 180 deg. out....

With the engine at TDC of the compression stroke, the installed distributor should have the rotor pointing toward the master cylinder. This will put the vacuum advance on the front of the distributor.


Amateur restorer. Well, sometimes I have been paid for it. But not right now.

as 22GT points out, you should have the Vacuum advance unit, if you have one, pointing forward.

really, it is best to install parts in the accepted position, there is enough confusion in the world already.
