Where was this number?

QUESTION How do I find the "list" number on my carburetor?

ANSWER The list number for most performance and factory 2 and 4 barrel carburetors will be found stamped into the upper right hand corner of the airhorn or sometimes called the choke tower. On the 4150 HP models that do not have a choke tower the list number will be stamped into the mainbody behind the throttle linkage. This number is used to identify the carburetor and also used when needing service parts or renew kits.

Then use:

Hello DuckRyder , it was stamped with inkt , i don't know exactly where, but it seems to come from the factory or a store because it's very hard to remove . I can't look at it now because a friend is working on my truck and he lives about 150 km from my place . I go this week and give more info .
Thanks already ,
