Good deal.
Any engine in a van is a pain to work on. (Actually, yours has a fair bit of room around the engine compared to the smaller vans "Astro" )
At the factory the engine and trans are mounted to the sub frame and the entire assembly are installed from the bottom as a package.

There are few parts on a van that are easy to work on..

The same van with the small block V8 are somewhat easier....but not much....

Enjoy the rig....
