I have been pondering lately the possibility of putting a Duramax diesel v-8 in an Astro. I know the diesel is wider and taller than a small block v-8, but does anyone know approximately how much wider and taller? I figured a body lift would help get it in there, and if I use the 4l80e from a 3/4 ton van it might not be too difficult to mount the transmission. Any constructive thought?
