John: You're mostly right. Per my AMC Parts books and 1983 Service Manual Supplement, AMC introduced the 150 (AMC) engine in mid-year 1983, at which time it replaced the Pontiac "Iron Puke" 151 engine. AMc never bothered to tool up a 150 install for the Concords & Spirits because they were already slated to cease production at the end of the model year (And, for 1983 the AMC 258 was the standard powerplant in the Concord/Spirit anyway). The AMC 150 became the base engine for 1984 Eagles, but the 4-cylinder was dropped for the 1985 model year due to poor sales, as less than 200 Eagles were sold in 1984 with the 4-cylinder. It simply wasn't worth the production line hassles for such miniscule sales. I have seen several 1983 SX-4s with the AMC 4-cylinder. Actually, I would like to find one as a future collectable.
