Sorry guys for the late response. I have been burning both side of the candle trying to get some progress.

Hair, I tried to find the can of paint but had no luck. I think I bought it at ACE Hardware.

Nathan, what all did you use to do the sanding and grinding? I ask in case anyone else might want to follow in your foot steps later one. I know I'll follow to some extent with my LT1. I love the look of them stock so doing some clean up to the existing design appeals to me.
Also, did you send the powder coating out or do it yourself?

I had my local powder coater do them. I sent the intake to "Mike the Powder Coater" in GA. He has refined the art of powder coating composite.
I used several dremels with different bits to help me speed up the process. This way I didn't have to waist time changing bits for different applications.
I buddy of mine showed me how to make most of my sanding bits. He called this one the flapper.
I literally cleaned out all the casting both inside an out! Here is a pictures of the crank case in progress.

And an after pic
After I had polished the outside of the block and the valley blasted to get grip for paint.
I had to search high and low to find a tank large enough to Ultrasonically clean the block. I know the owner of a local racing transmission shop that has one, but it wasn't large enough. Before they spent $20,000 on their tank, they'd just hot tank the parts after machining. Even after cleaning the parts, when they'd dyno the trans, they'd check the filter and still find metal shavings! Which is the reason they bought the Ultrasonic Cleaner. In my case, I also felt a bit uneasy due to the fact that I could feel media from the blasting which could have potentially gotten into the valleys.
We also bored the cylinders 15 over which throw metal shaving everywhere. I wanted to make sure the block was surgically clean.
I called airports to see if they had one big enough and no luck. Finally, I found a race engine shop who had one and did it for me.
