Well, after alot of discussion with myself and others, I decided to go ahead with relieveing my C2AE block along with some other mods for this blower application. I didn't have a piston that was a good fit for the bores, so I made a template out of a hardwood block for a guide while using the carbide cutter. I think it worked out pretty well. I also drilled out the hole for the early style road draft tube using a 1&1/4" carbide tipped hole saw, removed the ridges and polished the center 3 main webs and ground off the casting marks and polished the area around the distributor hole for easy cleaning. I'm on a roll now
