Hello,

I am working on getting a 64 GTO with a 455 moving, that has been sitting in my parents garage for 25 years.  We have taken the main block down to nothing and had it cleaned. New cam, lifters, pistons balanced.  But we can’t figure out the year. I think it is between a 71-74 block number 485428. Not sure how to translate B012 8 DN.  

Any  insights would be fantastic. This has definitely been a learning process.  Thank you
