'50 Super 8 distributer cap

Post by cetaylor » Sun Jan 31, 2021 5:01 pm

Folks,
I changed my plug wires and plugs on my '50 Super 8 a month or so back. This evening I decided to change the cap and rotor. I made the mistake of swapping my wires to the new cap one at at time and then realized the vent hole in the new cap is 180 degrees from the hole in the old cap. At this point I printed off the tune-up sheet that is in the information section of the Club website. My question is which is the #1 cylinder on the cap in relation to the depressions in the cap for the hold down clips? Any ideas?

So many things could have changed since original assembly, the simplest thing to do is go back to basic principles. Remove #1 spark plug and turn the engine over to bring #1 piston to TDC on the compression stroke; insert plug wire for #1 into the cap immediately over the position of the end of the rotor. Then, in the proper rotation, add the rest of the plug wires in the firing order (1-6-2-5-8-3-7-3).

Adding emphasis, make certain you have #1 piston at TDC on the compression stroke, NOT the exhaust stroke. And make sure you know if the rotor rotation is CW or CCW.

Dave,
I thought about that, but I normally find TDC in an engine with a dial indicator. Is the plug hole above the piston in the 327?

You don't need a dial indicator, you have the degree marks on the vibration damper. I just remove the plug to feel the escaping air to know the piston is rising on compression rather than exhaust. Some folks lay a penny over the plug hole to detect a piston rising on compression.

The spark plug is positioned over the valves.

Well, I used Dave's advice and found my #1 position in my distributor and installed the new cap and rotor. The old parts didn't look too bad, but the engine runs much better now. I am shocked at the difference in power. Sometimes a simple thing can make a big difference I guess!

Quite a few ignition components degrade gradually over the decades without actually failing. The coil is a good example. So as you have seen, returning everything to the correct specification and clearances, etc can make a big difference.

I often say to those contemplating disc brake conversions and the like, return it to the correct factory spec and you will have excellent performance without the huge effort and spoiled originality of a conversion.

Glad you have the `50 running well. How about a few photos?

I bought the car in November of last year. So far I've had the complete braking system replaced, the rear differential gasket changed, the oil pan dropped and cleaned and the idler arm replaced. I had my mechanic do that work. I have changed the plugs, wires, regulator, horn relay, distributer cap and rotor myself. The former owner was Paul Teets. He had the car for 49 years. The car looks great and now drives and stops well.
