Motorhead help...please

Can one of you motorhead geeks (I say that with MUCH admiration) please help me decipher this engine that I'm about to slap into my 76. It has been modified from stock bore (40 over)and has some other goodies like flat head pistions and Summit 1108 cam, but I'd be interested to learn the details of this block. It seems to be close to the proper year (77?) but that's all I can figure...
Thanks! Diesel

3970010 is a 350 used in many Chevrolet applications. Yours was cast May 29, 1974 and was assembled in Flint, MI. The code TJY was for a C10 pickup 165HP.

not silicone under the head gasket is it (hope not!)
Is this something you just bought or are considering buying?

Hi,
And, the block was cast on the day (D) shift on the 29th during the 4th (?) hour of the shift.
Regards,
Alan

How do you guys know this? Is there a reputable website that can help me decode one I have?
