They did not put hydraulic lifters in trucks only cars.
Did you locate the date codes. That would pinpoint what year it was cast. They will look like B206, F19, E125. The first digit will be the month represented by a letter (A thru L). The next would be the day, which can be 1 or 2 digits and the last would be the year. They only use 1 digit and repeat every 10 years. So in the examples I have given, B206 would be February 20, 1956 (could be 46 or 66 but we already narrowed it down to mid fifties or early sixties). In the second example F19 would likely be June 1, 1959 and E125 would likely be May 12, 1955.
Let us know how you made out or if you have any other questions.
