Intake paint for 66 L79

[Donald H.]

This is regarding the aluminum intake on a 66 L79 engine.

The TIM&JG says there is "a light spray of aluminum paint on the sides" of the aluminum intake. I assume this was to cover the black phosphate mounting bolts.

Further in the TIM&JG it says "The thermostat housing is cast iron, painted silver".

I have the LIC dull aluminum paint for the intake, but my question is the thermostat housing. I found another thread that says "The thermostat housing is installed on the intake manifold before any paint operations so the housing, bolts and the edge of the gasket will be coated with dull aluminum paint".

Should the thermostat housing be painted with the dull aluminum or with silver?

Thanks,

Don

Thanks. I had seen the one that was specifie to the 67 L79. Thats the one that raised my question. That the one that says the thermostat housing was painted dull aluminum with the manifold.

Msybe what I'm missing is the housing was pre-painted with silver then got shot with dull aluminim when the intake was sprayed?

Seymour dull aluminum is a perfect match. Use on thermostat housing, intake bolts, bracket, etc. per judging manual. I did a lot of research on the issue of dull aluminum and/or silver. I have close up pictures of original intakes and thermostat housings that clearly appear to be dull aluminum. They surely show there were not two colors used...one on the T-housing and another on the bolts. Certainly the thermostat and intake bolts were not painted different colors since they were painted after installed on the engine. GM was not that wasteful. I think you will find people are using the words "silver" and "aluminum" paint interchangeably. And such are problems between judging manuals. I just went thru this with my 67 350 HP resto last year. I had my aluminum intake and valve covers "cleaned" to new by Jerry MacNeish and the Seymour dull aluminum paint was a perfect match. Of course I might be prejudiced on the brand
