Call Davis and ask them would be best
They are one of the only people using the very old —-Sun dist machine — used back in the day that can correctly calibrate the stock 63 64 dist to stock specs if that should be needed or checked for its current condition
Our older style dist are very different than many new designs that are electronic used in all cars today
A very special service
Are you using any of there available dist replacements upgrades in your 63 Cadillac or in your 73 ?
No. Justv73, it came on car when bout. Had some missfires, and hv it down to wire problem, so replacing them
The ignition wiring is very often overlooked and if not replaced will cause a visible arch in the dark from the wire to the nearest engine metal ( a blue spark ) Ask me how I know !
If you get antifreeze on the wire covering from an overheat issue ( broken hose ) it will damage the wirings covering and cause a problem
Ignition wiring has a long term maintenance interval that adds to the issue of them not getting changed as they should
Just Love when the engine runs Smooth and Purrrrrrrrrrrssssss ! ,
Making the experience so much more ENJOYABLE
The 73 came w the distributr i posted, for part reference. Its funny, when i bought tge car, it tokk off at lights like a spotted ape. I thought it wss either an accelerator adjustment needed. It just jumped from dead stop. Had to consciuously ease it on for smooth take off. Now, unknowingly, and upon futther readings, these belden premiums should be fine. But after replacing all 8, takeoff is smooth as butter. No hesitation or missing, even at cold engine. I am jist hoping that they werevall in some sort of worn condition and new wiring git it bk on line. I cked timing, all was as it shoud be. The whole acceleration is just much smoother
Enjoy getting your engine back to running smooth again
One of my very own joys in life — BAroooooooom !!!! —-LOL !
