How to Body Drop 89 Astro Van

A friend of mine is getting ready do start cutting on his (previously daily driver) 1989 Astro Van. We have done some major frame work in the past, so it shouldn't be a huge challange, but we were interested in collecting any information that is out there on how people have already done it & what problems we might run into. We are most concerned right now about the engine fitting. It's a 4.3 Any replies would be apperciated.

^bump^

no body has done this?!?!
