Looking to build a high RPM screamer for my latest Z/28 project and would like to find a good 6618 block to build a motor from. Ideally, a February cast block and one with a DZ stamp between V0217 to V0224. I don't need a crank, rods or anything else...just a good block at this point?
Anyone have a 6618 DZ block squirreled away? 
Let me know, P&T
