I'll post pictures of my carbs in the white tomorrow but here's what I've done. I did one carb first and then did the same procedures on the two remaining carbs. I bead blasted the carbs, washed them in hot soapy water and dried them in an oven. Waited till they cooled and then sanded the mating surfaces until they were flat (using a straight edge) and then ensured all the mating surfaces were flat and even (no light escaping from the carb bores when viewed from the side).
I then used an 18" mill bastard file to flatten the top of the intake manifold. It needed it becaue one of the pillars that holds the center carb was a little high. Everything sits nice and flat now.
I bought the carbs and manifold at Carlisle so I'm not sure it's a matched set. The manifild is dated 12/67 so it's a '68. I'll post the carb numbers to see what you guys think. The one problem I had in matching surfaces was with the center carb where the are two triangular studs at the back of the base plate. They were a bit high, causing the back of the carb to sit high on the base plate. I split the difference and filed the studs a bit and sanded down the back of the carb and now the carb sits perfectly flat on the base plate. Any ideas about that? God knows if the base plates really belong to the carbs, etc.
So far, so good. I'll see what the powder coating looks like when I'm done.
BTW, I need a set of butterflies for the rear carb because it looks like somebody in the past dropped something down there and it nicked the edge. Can't really tell that until you take the butterflies out since they are beveled. Any one know of a source of the butterflies?
POST edit...Holley offers the butterflies, I just need to do some measuring. It's only money.
