Paint vs Powder
Why don't people powder coat their motors vs painting them? Is it a heat issue or is paint stronger. Or just easier?

I have done smallblock intakes and small block rocker covers, I have not even considered heads or blocks because they won't fit in my easy bake oven. Logistically powder is a bit more challenging because the parts would need to be done right after washing and prior to any assembly.
If someone has done it I would love to hear the results.
I just use an Eastwood hobby gun and conventional cook stove

Ive read somewhere that Roush Racing powder coats the entire block inside and out....then does all the machining after...
I think that Harley also powders their air cooled motors before machine work as well...
I dont think there's any problems doing it its just the time and work involved with it.....paint it easier and faster..

powder coat will stand up to the heat. It bakes @ 328 degrees for .5 hour. I did my out drives and they turned out and held up great. Just a lot of taping because u don't want powder coat where it doesn't belong such as on threads or where gaskets or o rings seal. Engine block would be tricky and heavy

If it can be done, I'm sure there would be a significant ticket price to get it done. For some that wouldn't be an issue. For me after spending nearly $500 to have two pairs of valve covers coated I think I'd pass on doing a block and heads.

Tom - I think you need a new powdercoat guy. I had my childhood go-kart frame and 4 wheels powder coated for about 150 bucks if I recall correctly during an ill-conceived restoration. Guy even had to re-sandblast it due to some surface rust.

They were a lot of work to get done… stripping and degreasing were a lot to do so I was told. The shop that did the work has a strong following and reputation. They came out great but for the money I could have bought a set of powder-coated Teague angled valve covers.

Powder stands up to scratches and corrosion better, but urethane clear stands up to solvents better in my experience.
Powder softens if you get a wild hair and clean the soot off your transom hardware with thinner whereas urethane clear doesn't even know its there.
