I was looking around and found someone selling a fully machined R1A race block for cheap.  The block is already at Ryan Johnson’s Shady Dell Speed Shop in PA.  It is a 48 degree block, has both motor mounts on it, 4 bolt main caps, ARP main studs, was CNC square decked to 9.560″ deck height, CNC bored and diamond honed to 4.070, lifter bores bushed for .904″ lifters, .060″ oil feed holes so it can be used with pushrod oiling if desired, has a short fill of hard blok, and was sonic checked to be good up to a 4.100″ bore.  This block would be great to use with W5 heads – I could really get some power out of them and not worry about having a stock block fall apart.  So today, I went ahead and wrote a check to the guy and bought the block.
