All 89 motors were Phase 3. The Phase 2 motors were used only in the 88s. Phase 1s were used in the 86 mules. What the heck you got the 'book'.

Tyler Tyler Tyler, I thought I did a better job training you on these "new ones" but there were both Phase III and Phase IV LT-5s in 1989. This one I suspect (if #014) is a Phase III, starting with #40 they were putting Phase IVs in the 1989s In fact from #55 on they were almost identical internally to the production 90s (with some exceptions) #004 has a Phase III with the machined PCV stuff and #058 and #074 have Phase IV "rubber boot" PCV setup LT5s.

#014 would have been produced in 03/1988.
