What we have here is the correct main carb body with C6OF-N stamped on air horn which fits all FE big block engines that FORD used mostly on 390's with A/T . Rare part is automatic kickdown rod linkage that can be seen in 2nd pic. Base is in EC and center squirter is there with screw and venturi valve. That pic didn't come out good. Air flapper has been removed for racing purposes but it can be used off donor carb. What you can do with this body is take a 3310 type common 600/750 whole carb and build a correct looking carb without spending big bucks to get original carb that still has to be rebuilt any way. I can do this for you or you can if knowledgeable enough to overhaul Holley carbs with chemical vat and correct kit. I have been modifying Holleys since 1958 when I took Holley carb class. one good thing about Holleys- parts interchange to match engine needs. Larger jets, squirters, econo valves ,etc. Holley lists lots of replacement parts too. Let me know if you want me to assemble and overhaul carb plus engine power demands and use-street or racing. Selling center body with base and A/T side linkage here only for $125 with free shipping. Base alone costs more new when cracked or broken plus no K/D linkage. Thanks for looking Take care and God Bless -VOTE fordmanted2b2b
