OK. Here's what his computer says:
Century, Achieva, Grand Am all used the same 3.3L engine in 92. Hollander interchange lists these as 92 ONLY because of some bolt holes that are not in later engines and 92 only harmonic balancer and crankshaft position sensors. I'm not saying that a later engine will not work with some parts swapping... just that Hollander does not list it as an exchange.
That's all I know.
