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. Tom Bunsey ---------------------- Tom, Umm....that *is* what I said! :) No Spirit/Concord 150s, only 84 Eagles and perhaps some late 83 Eagles. Yea....that's what I said!...and I think I spelled it all right, too! ;) John On April 3, 2005 John Rosa wrote [edited down]: > To my knowledge, no Spirit/Concord ever got the > 150cid AMC four, ...
