You need to get the nubers off the passenger side of the block on the tab below the front edge of the head. That nuber corresponds to the size and birthplace and date of manufacture. The last 3 digits determines the engine size and car.
Engine ID Code Example: V0101CLJ - (V = Plant, 01 = Month, 01 = Day, CLJ = Engine Suffix Code)
Another example: T0830CTY - (T = Tonawanda, 08 = August, 30 = 30th day, CTY = 1970 396 Camaro, 375 hp, 11.0:1, TH400)
Hope this helps give me the numbers and I should beable to determine it.
