454 block id
trying to decipher the codes of rebuilt 454 i just picked up. Looked at links here and online and have not quite come up with anything. I found the heads ok. The number on my block on pad by timing chain cover are cf3325070 and 4610. On rear of engine it is stamped M IV Hi Perf, H445, 14015445, GM1P. I am just trying to find out what year it was made for parts , accessories, etc. Not sure if this is a 4 bolt main , good motor for mods, etc. any links or help would be appreciated.
