Slant 6 in a 99 Durango?

That slant is from a Volare/Aspen. The Sanden AC compressor is the give-away. It would have a hydraulic cam. Must have been a lot of thought and work to install it, so must give the developer credit. Add a turbo, Offy valve cover, and it would look nice and go fast. Most importantly, it turns heads at a car show. I knew a guy who pulled a 2 horse trailer with an 80's Dodge truck w/ slant.
