I had the pleasure of working on a slant 6 Chrysler engine that was cast in the early 1960's. Aluminum bock and head. So all the OE's were giving a hard look at the new lightweight material for all sorts of uses. The "self porting" idea of the Pontiac exhaust manifolds was a really neat application!
