Howdy Chuck, this was my second repower of a smogged vehicle. I had to use the newer year engine or the same. As for being heavy duty, I used a heavy duty engine(only real difference with the 6.2 is the intake manifold and the built in egr) because of its slightly better flow. All other pieces worked and passed inspections. Of course I smiled alot and told them how rough they(state workers) had it. I'm also a state worker, so, I don't think that hurt.
