Up for grabs we have a nice rebuilt Holley 847 carb for your 42-49 KB6,KB7, K6 and K7. Fits 250 and 269 6 cylinder engines. It’s in really nice condition, almost looks NOS??? Slight amount of surface rust on the bare steel parts. This came in a 60 carb buy out, we’ve sold 21 with no problems at all. I doubt you’ll regret buying this beauty. Thanks for looking and thanks more for buying!
