This casting code is from both two and three freeze-plug small-block 400's from '1970 to 1973. These blocks can also have 2 or 4 bolt mains
it has about 750 6.48v8 horse power
The block casting numbers are on the top driver side of the bellhousing flange at the back of the engine. The engine code is stamped into a pad on the block deck in front of the passenger side cylinder head.
you need the date code on the side of the block it will be a series of numbers and letters first its the month, then day, then year
