Reply to "Holley Carb rebuild kit"

Tim, this comes up roughly once a year. See post on 12 May 2016 for discussion on 'Correct carb/manifold combo'. It's difficult to research this directly since Holley as a company has been sold at least once and changed their carb numbering system at least twice since 1970 (48 years ago!) During that time they've built thousands of carb variants.

FIA-legal GTS/Gr-3 Pantera club-racers were homologated with a Motorcraft 4300-D carb and could optionally use a Holley 4bbl carb #213, which crosses to a Holley 650cfm (mechanical secondary) double-pumper list #4777, along with a DeTomaso square-pattern aluminum intake manifold, as shown in the 'Gr-3 Supplemental Parts Catalogue' from DeTomaso-Europe 1972-onward. Note also the same Catalogue shows an optional Weber 48IDA two-barrel carb, 4 units to be grouped on another aluminum 'DeTomaso' intake manifold.

To maximize the confusion on this subject, the FIA has changed their specs for Gr-3 several times, and loosened the requirements for legal parts used today in Vintage competition. The Holley List # 4777 is still made, though.
