I am contemplating buying a 1968 Camaro basket case built in Norwood. The block casting number is 3916321. As you know, this is a 427. This block has the VIN on the deck that matches the cowl VIN, along with the MT stamping. The block casting is dated in October (didn't write exact day down) 1967, the car's trim tag indicates the body build date is the second week of March 1968. It has GM aluminum heads dated 2 days apart, about the same time as the engine block was cast.
From the research I have done, it doesn't appear that a 1968 L89 came with a 427, only a 396/375. Is there a possibility that a 427 could have been an option. My research shows not, but want you all to weigh in on this.
Also, is there a 1968 L89 OR L78 registry with the VINs anywhere for those cars.
Thank you all for your thoughts.
