Hi Guys, Just got hold of a Holley carb which I want to stick on my Buick 350. The thing is, the numbers don't tie up! Stamped on the choke housing are the following numbers:- D2HF-9510-DA LIST-6339-1 1835 any ideas? Cheers, Spence
Check Holley's website. I think they have a reference chart that tells what List # is what and what application it served. any ideas? Cheers, Spence[/quote]
checked but cannot find this carb mentioned, one site comes up with these numbers as a single barrel holley, nope!
Well, according to my Holley OEM parts breakdown book, that list number comes out to be a Holley 4150, originally spec'ed for a '72 Ford truck, 391 engine, standard trans, California only. Sound about right? Roger
that would make sense, that is what one of the previous owners said but I wanted to check for myself as you know how things get mixed up! So, 391 truck would be around 300bhp, the 350buick a little less but with a mild cam and tubular headers I shouldnt have to rejet the carb then, just rebuild it. Cheers, Spence
That's a governed carburetor from a medium duty truck. I don't think you'll be very happy with it from a performance standpoint.
If you ever need to ID a carb try this web sight thecarburetorshop.com They have the ID and parts for carbs for cars trucks and tractors. I us the sight all the time.
I have two holleys that I am having trouble finding anything out about. The first one was given to me from a friend he said its a 850 out of a 427 government truck. for one the thing it is just huge,in length it is the same but its wide (has governer and the rods for the blades are noticeably longer) . someone told me its for industrial big trucks with low torque (not good for performance) anyways here is the list #80475 and the other number on the horn - 1733 then i have what i believe to be a holley 750 vac secondary, it does appear to be a performance carb. the list #80145 and the other number on the horn - 0170 i have googled the hell out of these numbers without any luck, any information would be of great help Thanks for your efforts and Keep on keepin on
My Holley book lists the 80145 but only tells me its a 4150 model with a 600CFM rating. The 0170 is probably a January 1970 date code.
Are you absolutely sure about those list numbers? My OEM Holley book doesn't list any 5-digit numbers. My book does list a 1733, and says it's a model 3160/4160 from a '58 Ford passenger 332 engine. Sorry, this book doesn't give me CFM specs. Roger
yeah im sure those are the correct numbers, i will post pictures when i can tomorrow, i saw another online with a 8145-2 that was a 600 . the 80145 looks a little large to be a 600 (large bowls and the double feed line to each bowl) you are probably correct and i was screwed by the guy i got it from, oh well thanks for the effort the industrial im not too curious about because i wont use it. the 80145 i hope is a 750 but doubtful if you guys are saying 600
oh and another note ( probably not relevant) i put the 80145 on my 350 engine and it seemed to load up alot, i switched it to what i believe is a 650 and it would run strong, i then tried the 80145 on my 454 and it runs sweet except when i do a full stomp it backfires. I dont know if it was another issue or if the carb was too big or dumping too much. If its a 600 then too big is not the case.
my books are at work. but the list numbers vary from 4 to 6 digits. The date codes will vary from 3 to 4 digits. If the carb has a three digit date code it left the factory on a car. The 4 digit codes carbs are over the counter replacements or aftermarket. The mentioned above date 0170, this would be the 17th day of a year ending 0. The three didgit codes, the first number is the last of the year.. Yes, that carb is a governor carb, they arent good for a car at all. These were for big truck, nothing to do with torque. They were required by the gvmt, to keep real heavy big trucks from being able to go as fast as someone was willing to drive them
also, most all big truck carbs are 600cfm or less. The small cfm cause a very strong signal which will help in down low RPM.
I can always remove the governer, what im really interested in finding is the list number for my supposed 750 which is a performance carb list number 80145 anyways thanks for the info on the industrial carb
forget the industrial carb Look up this one if you guys can find it. 80145 56 don says its a 600 cfm i noticed the 80145-2 was a 600 i couldnt find anything on a 80145, he is probably correct i just don't want to face the facts a second opinion would help me believe
80145 is a unversal / performnace 600 cfm square bore carb. primary venturi 1 1/4" throttle bore 1 9/16" secondary venturi 1 5/16" throttle bore 1 /9/16"
The dash numbers dont really mean anything to end users. It is a engineering number to identify some type of change( could be a different part, different process or possibly a different vendor of same part )
man that bites the big one then, i traded a 650 double pumper for a 600 oh well i guess i just need to spend 400-500 bucks for a real mans carb thanks everyone for all the suggestions and effort i feel like a chump Oh well its my fault take care and keep on keep'n on
hey guys i have another question, i have been talking to some people that think they know whats going on with this supposed 750 that the main body is listed as a 600 it has 65h jets, they tell me it has been modified . it has two metering blocks, they said that 600's only have one metering block this has two, is there any truth to this? or is this guy ganking my chain .,
Anyone can switch those over to 2 metering blocks... I have a standard R-1850 600 cfm Holley with 2 blocks instead of one and a metering plate.. Plus I have the performance fuel bowls on it... It's one of my favorite carbs that is tuned for mileage and performance...
thanks deuces that explains alot, what all is done to make smaller carbs bigger or is that not an option?
You can't on a 600.... You could make it flow more cfm by milling off the choke horn and rounding off the sharp edges...
What's cool about the Holley 4's with vacuum secondaries is with the right know how, tuning equipment and calibration kits, you could make these carbs do what you want them to do... Just need to put a little time in them..
