yes E is the foundry, 9=1969 j=sept 28=28th day
if there are ribs running down the sides of the block they are an inch or so wide and are raised about 1\16 to 3\32, then it is a service replacement block.
if no ribs it was still part of production for parts sales. some will say the service blocks are not as good, but for a street application it will probably outlast you.
if the block checks good and has no issues use it. if it has issues and you need a good one let me know i have a motor on the stand fresh from the machine shop and a balanced reciprocating assembly ready to go.
