The E7TE is part of the engineering number, which has the first two numbers, the E7, as the decade and year within the decade. The C is 1960's, D is 1970's, E is 1980's, and so on. The last two characters indicate the manufacturing line and the part type, which would be T for truck and E for engine.

This is not the date code for casting. The 3 or 4-digit alpha-numeric date code is on a small panel, typically just above the engineering number. The date code starts with the year of casting followed by a letter representing the month, and then one or two more numerals for the day it was cast.

You will see C5AE-6015E 6-bolt 1965 blocks with something like a 4G24 date code (April 24, 1964), because Ford began casting the '65 blocks in mid 1964. Likewise, you'll see C4OE-6015E 5-bolt blocks with something like a 5B3 (February 3, 1965), because service blocks were cast in '65.

The OP will need to find and read the date code, not the engineering number to determine the date the block was cast. Find and post the date code and we'll tell you when it was cast. Hope that helps...
