1969 440 assembled at the Trenton plant
T- Trenton plant
440- CI.
E- 1969

There is no "truck" designation.
If it was a cast crank motor the stamping number would start with 4T through 8T (1974-1978) or have the designation G,H,or J, for 1971-1973. Cast cranks were introduced in 1971.

The block casting number on the side should be 2536430 (1966-1972)

Incorrect , the E would be BEFORE the 440 if that were a 69 model year engine. As AndyF said the OP needs to look at the pad again and tell us what number is BEFORE the T as you noted how the stamping change beginning wit hthe 74 model year , the E after the 440 denotes a CAST CRANK .

As far as cast cranks in 440's , not till sometime in 73. I have a virgin 73 440 , NON HP , it's got a forged crank . The first big block to get a cast crank was the 383-2bbl motor in 1971 .
