What color advice.: POLL

I'm going to run this setup from
A 71 only 383/440 HP, the consensus is that it from
B body

Im leaning toward gloss black powder coat

I want to leave it original except possibly for
Paint

The red is going on the spark plug wires, with brief spacing to show yellow wires

I'm trying to get the parts to make the hot air door working to let the air into the filter
to keep the temp in the housing to maintain 100F,

I read up on it. I had not known that in cold environments
Without this arrangement the paper filter would freeze, blocking air

According to the article,

Deicing
Emissions are lower at 100F
Provided running smoothness

I will be in Denver in early June, don't want and ice related conditions the coming winter
