Intake Painting
I'm working on the eninge today and while I'm at it I wanted to clean up the intake manifold. I have some paint I picked up from autozone. The color is called cast aluminum I believe. It is for eninge blocks and good up to 500 deg. I used it last weekend on my AC compressor, PMC, and alternater and they came out great. What about the intake? Is it better to polish it? I noticed it sometimes gets very hot. Will the paint trap in the heat even more? If so I'd rather polish it so it would stay cool.
Thanks

Not sure about the intake but you might do what I did on certain parts. Mothers wheel polish on the AC compressor, accumulator,refrigerant lines, upper control arms..........they come out with a shiny chromelike finish............just follow the instructions and you'll be good to go.

actually, a polished surface will emit less heat than a rough painted one, plus polished alum needs periodic attention to stay pretty.
older cars had exhaust piped thru the intake mfld and the heat was too much for paint, but your vette does not have that problem.

My black setup before going poly-chrome coating was : sanded, then primed, then dupi-engine enamal and baked at 400 deg for 20 minutes between each coating (4 coats), then 4 coats of clear, each one baked. came out hi-gloss power coat looking and smooth, the dupi engine enamal is thick stuff and fulls the voids... takes some time, but very nice finish
