The inside of the pan? Not for looks but so sludge/deposits don't have anything to stick to and build up on. Even with regular oil changes deposits start to build up. I had already smoothed what portions I could of it.

 

The etching doesn't really alter the surface it just preps it for coating. If you look closely you can see the original shot peen marks.

 

Can I assume you work at some sort of specialty coatings facility?

 

Nah....just bought a $30 Harbor freight blaster, some media, and airbrush kit

 

Etched and coated the cam today...tomorrow I'll burnish it with the 0000 steel wool and next week after it's fully cured I'll buff/polish the coating.

 

Interesting. i hope this never causes any lifter issues for you.

I know they're buried in here somewhere... what are cam specs?

 

I am really curious to see if all this polishing and coating works out well, or if you trash a $10,000 motor because you had too much free time on your hands

 

235/242. .621/.615 118+5

 

Me as well

 

Which heads? Interesting cam choice for a blower...
