 :-\ Hi to all smarter than me, # (1) is 7028267 and # (2) is 7043274 I think #1 is 800cfm and they both need rebuild. I'm no expert on carbs and don't want to mess them up. Any help with what I have and how or where to rebuild them would be great. I need the carb for my Pontiac 400cu.in. with slight build. Thanks Mike  ???

 Welcome to CHP!

 7028267 is off a 1968 Pontiac and Tempest 400cid/428cid, M/T

 7043274 is off a 1973 Pontiac and Tempest, Grand Prix and Firebird 400cid, A/T

 I do not think either of those carburetors are 800CFM, though.

 Yes, 7041540 is indeed an 800CFM version off a 1971 Buick Electra and Riviera 455cid, A/T. ;)

 :) Ethan, Once again Thanks. If the 800cfm is a good fit for my engine I'm going to send it to  Cliff's for a rebuild, and get a kit for the other and try it myself so I have one to run on tell I get the 800 back. I will probably need a little when I cross that bridge  :o Thanks Mike 8)
