Just picked up an aluminum block from Robert Pond last week for my SOHC build,also purchaced a Scat billet crank and matching rods as the rod journals are BBC dimensions. Pond blocks are true side oilers where Shelby uses their own design. Both blocks are designed with deep threads for head studs. Pond blocks have original Ford casting dates cast into blocks. My block has the rear
oil drain holes drilled for the cammer application as well as none drilled lifter valley (no lifters). My engine builder (Art Chrisman) said the parts looked "*****in". I think both blocks are good but went with the Pond because of originality looks.
