Ive been working on rebuilding this carb for my 1970 cougar with a 351w,It is and H code car matching numbers, it origonaly was suposed to have a 2v carb, when i bought this car it had a 4bbl edlebrock intake with a 4bbl carb, The date code on the carb is C9LF-A im pretty sure its a 4300 no tags where on the carb. Would this carb be correct for the motor? Also what does the date code mean?
Thanks
Aaron

C9LF-A is not a date code. It is a part number abbreviation. It is a 1969 Lincoln carburetor. Not right for your application but if it runs OK I would leave it on there. That is a 470 CFM carburetor.

C9LF-A should be a 4300 for a 429 Thunder-Jet, the standard passenger car variation of the 429. Those typically came with a 600 cfm carb. Check the bore size. If it has 1" bores its a 470 cfm. 600 cfm version will have 1.25" bores.
