Good Evening, All,
I have recieved a nice rebuildable core Carb- series 9103 - a 77 400 HP application that I'd like to use on a set of 302 heads I'll be installing soon on a 273 .
I have been doing my research and I have noticed my target carb- a 1973 340 AT unit has the same Primary jet- 4098/ .098- but has a smaller secondary jet -5143/.143 existing compared to the desired 340 jet- 5137/.137 - and smaller metering rods -existing 2211- compared to the desired 340 AT metering rod 1966- so is this , if I can find the parts , a good idea ? and if so , a reasonably do-able one? What else will I need to be on the lookout for as I try to make this swap to this late model carb? I've already ordered a set of the brass floats and a shop manual , along with a rebuild kit.
does anyone know what the second set of numbers below the model number mean ? Mine has 103 S below the 1903 S on the base plate..
Thanks and Happy Holidays to All!
