Yes, there are a few 4000Q's running around with the 2.3L motor, just
as there area few Coupe GT's with that motor. Both were built in the
final months of the '87 MY. The easy way to tell without opening the
hood is to look at the side mirrors. If they are body colored, it's a
2.3, if they are black, then it's the common 2.2. This rule applies
to Coupes and to 4000Q's
