Thanks for the compliments, I looked into powder coating, took too long, too time consuming/expensive/fragile.
When I did the LT4 conversion, the intake was powdercoated red, looked rice. I block sanded the ridges on top of the intake and polished them and the fuel rails out, then I sanded the intake and the block down, hosed everything w/ brake cleaner to get rid of the grease/oil, then sprayed everything w/ Duplicolor Engine Enamel # DE 1620 from NAPA, has ceramic in the paint so it holds up to high heat conditions. I went through about 3 spray bombs doing the block, oil pan, intake, and misc stuff. Also, going w/ the spray bomb, it's easy to touch up if anything happens and cheap to replace. After I got finished spraying everything and it dried *heat lamp from Home Depot*, I threw some polish on it to get rid of the overspray/protect it, looks great! Don't worry about little flaws, just about everything is covered up w/ hoses/wires, I about had an ulcer on somethings that just weren't worth worrying about.

I also smoothed out the accessory bracket, filed down casting flash, etc, and sprayed it w/ silver/aluminum paint, dried it, than polished it as well, looks awesome, just like powder coating (used Eagle 1 Wet).
Good luck man.
