i had a 600 holley and i gave it to a friend of mine, and he had a dp sitting around and said that i could have it...... he thought it was a 750, but when i searched for the pn i got that it was a 850....now i am curious as to when this style of carburetor was made.....the production date on the carb is 1528, which i believe would be june 1st of some 19X8 year....but i wanna know if these carbs were made way back in the day or more reacently.....

the carburetor number is: 80781

any help woud be great...thanks!

 

Holley has all their list numbers and specifications on their website.

 

i looked on there but it didn't help any more than what i already have decoded.......

 

What are you looking for then?

 

well it seemed like the newer carbs had an L or said list and then had the list number....and mine doesn't, but also they say that in the sixties they used a 3-digit code, so i know it's not from 68.......so im trying to figure out whether or not it was made in 78 or 88, and also what kind of carburetor it was considered......like a high performance one, or just a regular double pumper.....

 

Its probably not much different from any other 4150.
