mopargem that was also my first thought until found the other 2 cars with most of issues. that's why I asked if there was a strike or mechanical breakdown on the assembly line that might have stalled production. the thought of running out of blocks is a stretch in my mind,thats why im looking for documentation of any mishaps at the assembly plant , but all three vin's close and scheduled dates as Barry stated and all three blocks with no vin numbers and all 3 same casting date. does anybody have the warrantee records? as far as no way that the car built in march could have 4-3-70 block I would have initially agreed with you but im reminded of the battle between welborne and castaluchi over who has the last hemi car built.(don't kill me if I spelled the names wrong) that's why I never say never, and that's why im trying to find more cars built 3-70 and 4-70 to see if there are anymore similarly built. by the mopargem whats your fender tag and door sticker dates?
