67 s code gta fb San Jose April
Just got carb back from restoration shop and the fuel inlet is a hose barb is that correct?
Not sure what your describing with the words "hose barb". That carb should have a long fuel filter screwed into the drivers side front fuel bowl with a end that allows for a very short flexible rubber hose to be connected
Generic Holley picture
Also how much time difference is acceptable between carb build date and car build date
Maybe what would normally be the date spread would be easier. Since you have a Holley and it appears these were assembled in batches rather than all the different types being produced every day of the year the date gap may be longer than what you would find in other parts that were being made all the time
With that said - looking at other examples I found 2-5 month though I would guess it might be as close as a month in some cases . Just the records I have available at the moment
Sure you have read how to read the date code on a Holley in the article located in the sites Library
