Need Engine ID

[stantheman]

This is a weird one. Bought a 68 Chevelle yesterday. Been sitting in old man's garage for many years. Drove it home. Wow! It has a big block and the fender says 396. However, I'm not sure what the enine is. The block tage at the front of the passenger head is stamped: TI 208 IV. I can't seem to figure it out. I know the engine was built in NY on Feb 8th (I think), but what is it??? The engine at one time was painted yellow! Any ideas?
