Technical Holley Carburetor question?

But the article also details some of the differences in throttle and transmission linkages which would explain the carbs having different production numbers. Though it doesn't say much if anything about tuning or calibration specs.

 

Lots of Holley carbs which are not in the current Holley carb list. Some of the unlisted numbers are in the older MPL's, but not all. Most of the marine/agricultural carbs are omitted.

Also, lots of the 1940's and early 1950's Holleys had an identification number (in the literature) and a LIST number (not in the literature). Holley hadn't really standardized until the mid-1950's.

I have a LOT of Holley applications in my database, which are not covered in the Holley carb lists.

For pre-1966 Holley carbs, the MPL's have LOTS more information than the "exception listings" from about 1966 and newer.
