Alright, I can't seem to find casting number info for this engine anywhere online.
I have what I was told was a 250 out of a 72 Nova and I am trying to figure out for sure what I have.
the casting number close to the distributor reads: 3994257 under that is stamped "GM 72" Back towards the bellhousing is stamped "L141" and then "CCN2"
If anyone can find out what I have please post it for me!
Thanks
Jason
