Engine codes

1 Attachment(s)

I've been through nastyZ28 way too many times now and I cannot find anything on any of these codes.. Casting number 3970010 it's a 4 bolt. I have deciphered many engine codes but for some reason this one is giving me a headache. Attachment 1460365

Re: Engine codes

TAY is either a 4bbl 350/250hp from a '70 K/10-2500 with TH350 or a 4bbl 350/175hp from a '72 C/10-20 with manual transmission

I don't know about those other stampings, other than must be from a rebuild
