ZL-1 block versus Can-Am block?

Well, that explains it. Thank you for the clarification and link Pete. I did see a few posts on other sites that said it was not Toy IV, but they kept responding and arguing that it was....I fell for it!! I am sorry I sent them a copy of the documentation/details I had on the block. I have not contacted the owners of the 69 or 70 cars. I think I would rather put in my car as intended at this point since I was unable to reunite with Toy IV.
