Chevy Orange Seymour EN-48 is what i used on my 72 Nova SS Small Block. Good paint. Recommended by Jerry MacNeish Camaro expert.

Seymour EN-48 for Chevy Orange and Duplicolor engine enamel with ceramic for primer. Good to 500 degrees

How the heck am I supposed to remember that name?

Anyone ever rattle can the block with hi temp cast blast paint before spraying the orange?

Lol

The VHT brand used to be one of my favorites. I haven't sprayed a motor in a long time but the last one I did is as follows.

I purchased a used motor that was painted a color the matched the car. Not sure what paint was used but it was almost impossible to get it all off without spending lots of time on it. So I tried the POR-15 chevy orange high temp paint you brush on. Just a little shinier than the rattle can but nice smoother finish that cleans off much easier. Very happy with it after many years.

I used Martin Senour paint in the past, it was available from NAPA stores. Very close match to the factory painted valve covers and engine. It is impossible to find nowadays though. Was the company bought out by another paint company or did they just go out of business? Don.
