‘67, 435hp
I have a close friend who has owned this car for over 40 years. Recently, he has been having issues with the center/primary carburetor. Could someone please let me know what stock are the stock jet sizes, power valve value, etc. Holley doesn’t make the R3660 carb anymore and used ones are in the 4 figures. I would like to rebuild it back to original by using the Holley rebuild kit, but it doesn’t include what the original jet sizes.
Thanks for any help.

Don't know why you will have to replace the jets, but it is there on the Holley site.

Over the years, I have had the carbs “rebuilt” and I don’t now what is in there now. The primary tends to be fine for awhile and then decides to not run well. I probably will have to send it out again, but I can’t seem to find a lasting solution.
