Are 403& 455 distributors interchangeable?

And Dick Patterson told me at Branson that the advance curves also are different for different final drive ratios.
I'm reasonably certain that my final drive is a stock 3.07. I hope to go to a 3.70/3.73 ratio eventually. Dick said that a distributor set for the 3.07 would suffer when coupled with a 3.70 but that one set up for the 3.70 would only suffer slightly if used with a 3.07.
With that info, I bought one there that he already had set up for my hoped for eventual 3.70 drive.

Mike,
Yes and no.
The dizzy's will fit either engine, HOWEVER, if you have a points dizzy in your 455 and you install an HEI dizzy the 455 the air
cleaner will not fit without modification.
The dizzy cap is larger on the HEI than the Points dizzy and it will hit the bottom of the air cleaner.
Regards,
Rob M.
