I have made a deal with my polisher to build an engine for his panel delivery truck in trade for polishing labor.
Therefore,, if you need something polished I would be happy to get it done for you at "cost".
In the past I have trusted him with some very expensive parts, and he has not let me down. I am in the middle of finishing up a polished all aluminum 621 cubic inch engine and he did the block, heads, dry sump pan, and Milodon gear drive, but all of that was completed prior to our current trade arrangement.
