I want to mention something to be careful of. I had a manifold on a build that was powdercoated. They blasted it before they coated it without flushing/cleaning the interior plenum and runners first. The sand is very fine and you need to rub your fingers on the surfaces to notice that there is sand in all of the pores of the casting. The outside was perfect and the inside coated with fine sand. I was very pissed off to say the least. The old saying is the builder is always responsible to check everything they assemble. Don't assume that the powdercoater isn't an idiot.Little 350 project is moving along thought I would share a few pics. The intake just came back for powder coat and looks factory, I told them I did not want it very shiny. The little GM box's hold good old gm lifters.
Thanks, I did bead blast it myself, but I will for sure be checking it.I want to mention something to be careful of. I had a manifold on a build that was powdercoated.
