I did a search on this forum for an answer before posting this question. I didn't find what I was looking for so I figured I'd put it out there and ask. I'm looking for a Holley list showing list numbers AND vehicle application (when they were OEM carbs). It's easy for the 4V Holley's but I what I'm looking for is for 2300 2V carbs. This whole search started when I tried to identify a Holley 2300 2V carb sporting a LIST - 8641. I can tell by some of it's features that it was an OEM carb on something, just trying to positively identify it. It's got a 1342 date code so I'm guessing it's the 134th day of 1962 or 1972. If anybody has a link to the 2300 LIST numbers index I'd love to see/save it. I tried the Holley.com site with no luck on this one. Thanks in advance
sure, I have a 1982 Holley book.... The R-8641AAA is an aftermarket replacement for a 1977 Ford 302 If yours is not the AAA model, then I don't know what it fits
Thanks for the info. Mine does not have the "AAA" after the list number. My carb vs. the picture breakdown = different carb. Mine has a different style mechanical bowl vent with the arm running over to the linkage. I wish I could get a pic to upload but I can't.
Well, I am looking for a reference that will tell me by list #, what application the Holley 4V is intended to be used. I would also like to know more about date codes on 4150/4160s. On 4 digit codes the last digit is the year, but a "4" could be 1964 or 1974 or 1984 or 1994, so how do you really know what year? Thanks, Walt
If you google the list number and the word Holley, and don't find anything, then maybe you'll have to post the number, and someone with a book can look it up. There are some clues to what decade a carb was made, but they're kind of subtle. Posting some clear, detailed pictures of the carb will let folks see what it is, and help you figure it out.
Jim, Thanks. I often buy used Holley carbs at garage sales and swap meets. I always look for 1850s or 3310s as they are universal 600 and 750 cfm carbs that can be used on just about any V8. I rebuild them with all the latest (upgraded) parts I can find including alcohol compliant gaskets and diaphragms, brass idle screws, stainless steel throttle plates, power valve fix for back-fire damage, etc. But sometimes I buy other List # Holley carbs just to get spare parts, and some of these are a puzzle. Do I use them for parts, or do I resell them because they are valuable to someone due to there original application? But what was that application? Internet info is often conflicting, so I am looking for an accurate source for such information. How to I get a Holley "book" that would tell me by list # what application Holley intended? If anyone can look these up, I would appreciate the information. I have a 6299-1, which is a 390 CFM, date code 2218 I have a 4548, which is a 450CFM I have a 9834-1 which is a 600 CFM and I have two 6919, 600 CFM date codes 1402
6299 - pinto HP 4548 - Ford service replacement- 390, 428, 429 D0PF-9510-U 9834- pre emission universal- electric choke 6919 - 1970-72 Ford 302-390
if you look on ebay, you can find a few different versions of the Holley Carburetor Illustrated Parts and Specs manual. Probably worth the money to buy an old one or two, for what you do. you would learn fun things like the 6299 is for a Pinto, and that the 6919 is for a Ford 70-72 pickup or RV. The copy of the book I have is from 1982. They had a lot of revisions, you probably need a few different ones to find all the carbs you're looking for. Mine does not list the 9834, but it has the others.
Thanks for the info! Holley often seems crazy to me; like a 9834 as a universal 600 cfm with electric choke when they already make a 1850 that is the same thing. Why? And a 450 cfm 4548 for a 390-429 big block? When a 302 takes a 600cfm 6919? Is that Holley or Ford that is crazy?
Many of those oddball carbs are Holley replacements, many were tailored to meet the needs of just a few engines, and comply with smog or mileage requirements. Not all Holleys are intended for maximum HP, you know.
Jim, I understand, I guess, but as a result there are likely over 300 List numbers for 4150/4160 Holley Carburetors. I just want to make sure that I don't destroy a core that might actually be what someone is looking for to restore their classic or muscle car. I will be looking to buy some old Holley manuals as you suggested to help identify what I find at swap meets and garage sales. Thanks, Walt
If the carb has a GM or Ford part number in addition to the LIST number, then it could be worth something for a muscle car (unless it's a later Ford truck carb, they had number like E0TZ-9510-xxx, the T gives it away)
If you cannot identify it, best to not destroy it!!! A comprehensive printed list such as you seek, to my knowledge, simply does not exist. A couple of sources: (1) Mentioned by Jim above: Holley Carburetion Illustrated Parts & Spec's Manual (2) Holley Carburetor Numerical Listing There are several issues of both. However, even if you buy one of every different issue, you still will not have complete coverage. Try looking up list numbers 1536 and 1599 in any of these. Hint - they ARE oddball Holley 4-barrels. I have at least 500 different numbers in my database which are not in any of items (1) and (2) above. Also, early Holley "list" numbers are NOT the identification number Like Jim said, pick up some of the items listed above on Ebay. And, if you don't KNOW exactly what it is, you probably DON'T want to use it for parts. Oh, and the 1536 and 1599? They are factory 1957 Ford supercharged Holley 4-barrels. Edit: here are a couple of ebay listings to illustrate the above: 331968216825, 311919891712 Jon
Just some updates: - I have ordered some old Holley tech manuals off EBay as suggested. - I found some info on the Holley List #6919, which I often see well-used at swap meets. It is a mid-1970's version of the Holley 1850 designed originally to go specifically with Holley intakes to improve the performance of 1970-72 vehicles, there were Ford/GM/Chrysler specific versions and they were often used on light trucks and RVs, and they worked well with a "RV" cam upgrade. In 1973 they were modified to add an EGR signal vacuum port. They were all Electric Choke models. The tend to perform well (improved over standard 1850s) on slightly modified 300-400 cid V8 engines. They have 1-1/8" primary and 1-5/16" secondary venturies. All 4 throttle bores are 1-9/16", and they all came with single feed side mounted float fuel bowls. So the big change is the smaller Primary venturies, 1-1/8" versus the 1850 which is 1-1/4". The 6919 has revised idle and transfer systems to provide improved fuel/air control. There were further revisions starting in 1975 for catalyst equipped engines, better yet F/A control to allow the part throttle F/A to stay closure to stoichiometry for catalyst efficiency. - All Holley 4150/4160s built prior to 1990 are susceptible to backfire damage to the power valve. Holley sells a kit for about $20 that gives you the parts and directions on how to install a "fix" that will prevent such damage to your power valve. I make this upgrade to Holley 4150/4160 I rebuild. - Today's alcohol laced gasoline is causing damage to deals and diaphragms in older Holley carbs, but there rebuild kits now contain upgraded components (watch any non-holley sourced kits as they may not be so revised). Walt
57-58 Ford, Mercury and Tbird 312 is the original application, according to my old Holley book, as best I can tell
If no one answers you tonight , I have a what I believe is a neat Holley list book . I will find my book in the A.M.
Thanks Jim and 41rodderz , Looking if option to put on the 51 V8 ford pickup. Just need more info and if good carb? Using this intake
