3A16: Block cast January (A) 16, 1963 (3).

NOTE: The waterpump and timing cover used before 8/23/64 are not the same as used from 8/23/1964.

The early 221/260/289 waterpump will not bolt to the later 289/302 timing cover. The T/C gasket is the same 1962/96, so the early timing cover will bolt to the later blocks, but only an early waterpump will bolt to it.

You do not have a 3 sheave crank pulley, because there is no such thing.

What you have is a single sheave harmonic balancer with either two single sheave outer pulley's, or a double sheave outer pulley bolted to it.

Accessory outer crank pulleys were used with dual belt alternators, P/S, A/C, T/E.

Since the engine was originally installed in a Passenger Car, it probably had P/S & A/C. No T/E until 1/1/1966.
