my block is one of 6 that were picked from the trash at the factory.The one I own took much work to make good.Core shifts and perosity problems were great.I pretty much know where all of the 6 are.There were other alu blocks out there from early developmental engines giving to M/T.There was a article in Hemmings muscle machine a couple months ago that showed that motor.There were hemi blocks made for M/T and im sure other mid 60s early 70s that were givin to the "hooked up" racers.The early 421 SD andd RA V stuff is my passion.Tom
