Orange Paint on '67 Carburetor Mounting Studs

[Rick R.]

On page 112 of the TIM/JG the following statement is made regarding carburetor mounting studs: " Stud tips may also be painted orange." Please comment on the following:

1) Does the above statement only apply to studs used in cast iron intakes? In other words, if there is orange paint found on the stud tips, it got there when the intake was painted orange.

2) The orange paint on the stud tips is an inspection mark and is found randomly on all engine models.

3) The orange paint on the stud tips was sometimes put there by the manufacturer of the studs.

4) None of the above.

Thanks.

Doesn't give a reason why ,but i would guess it would be a Carburator stud and nut inspection paint mark ,just like the chassis paint marks #2

If it were a inspection mark it would likely be only one stud with paint on it. JG says "studs" which would likely be paint from painting the intake manifold.

If was part of the intake spray it would of been along on lower section of intake up to the intake bolts, but there talking small orange tab on top of each studs , see the photo 112 113 look at the Carburator studs there a tab of orange paint on the studs not a spray.

didn't Flint have the engines hanging on a over head crane system and the engines had a plate on the carb opening for the chain to attach? if so don't you thing doing the painting process orange over-spray would get on the top of the studs.

Yes I can see that happening , but figure a painter with a spray gun painting a engine block and valve covers and over sprays up to the lower intake bolts , but how you get small orange tab only on the tips , who knows it could be like your saying over spraying when painting the engine

The whole paint required to be on the tops of the studs sounds like somebody’s “made up thing to deduct for”.

For engines with cast iron intake manifolds which were painted as part of the engine assembly, there was some sort of mask that was used to prevent the carb flange from receiving any paint. This mask may have also covered the carb studs. However, more likely, the carb studs were also protected by cardboard tubes, likely open-ended. So, when the engine was painted the tops of the studs also received paint.

I would agree with the cardboard tubes, that also happened on the long mounting studs on the water pump of big blocks in C2s.
