I inserted a photo that I found online of the LRT's being built at Tecumseh Truck (Chrysler Canada). These were 1978 Model year. I recall the 1979 model year and all the rumors about W2 heads, etc. Most of the excitement back then was because of the performance of the prototypes, and people mistook it for the production models. There is a very good article linked in post #50. Another 2 pics from the Packard Proving grounds 2 weeks ago. A 1979 LRE, engine part# 4115300.
