Bob, I called the shop they do have them, the number does not corelate to the size of the jet for Chrysler, the hole size I did drill thought is about 2 mm larger the car runs great on accelaration power mode, the light cruising will still be a bit lean since I found out the carb I have is a California spec carb, smaller air bleeds. if this is true than I can leave it alone. I would rather keep this original style carb and run a bit lean than buy an after market Carter clone and take a chance. Plus I show the car and want to have the original look and feel. I do remember now back in 1982 I bought a new Holley Economaster carb I used that until 2008!, the plugs were a light tan, but I would loose power on long hills and still have great power on a hard acceleration. I did trade that carb in since it was worn out but lasted 20 plus years! dummy me for buying a 100.00 rebuild from Advance auto that lasted about 7 years it made the car use more gas but ran great. After only 8000 miles it started to pop, Ethanol damaged the acc pump. at that time I knew nothing about carb rebuilding it seemed overwelming to me at the time, today however I will get into everything because I want to learn more and not afraid to try and repair my self. The older I get the more curious I have become. I think I will order a set of those long jets and have a spare if I want to experiment with the performance, as of now the car has a quick snappy feel off the line and just is so much more enjoyable to drive for a 318, two barrel .430 inch cam duel exhaust car with 321 rear. Now I want to go back on the dyno.
