Re: Block I.D.
There is a block casting number on the back bellhousing flange on the drivers side.
What is that number? For example, something like 3970010.
If you go to the center of the block, behind the distributor, you should see a casting date, usually a letter followed by 2 or 3 numbers. For example D 23 9 would be a April 23, 1969 or 1979 date the block was cast. These will narrow it done to the year and application.
If the front pad is stamped post those also.
