it just all depends on how much you want your car to look weird (boat tails, kambacks, wheel covers, exc.) and how much you want to spend (scan gauge II would help alot)
Take great care implementing a grill block on these rigs, the blasted things love to overheat for some reason, especially the unddesigned transmission. I would simply make sure to have a decent temp guage for both the transmission and motor before doing this (and pay attention to them). In the winter you are gonna get away with a lot more unless you drive 100+ miles.

And I 2nd an air dam, with an air dam you should be able to block much more of your grill and reduce wind resistance under the van, lowering the van also helps on this. In other words there are easy ways around needing a belly pan.

And i massively agree on a scanguage or vacuum guage. They let you see visually & compare what actually works to what doesn't. Driving technique will be responsible for 70% of your fe improvements, unless you make a boattail van

Good Luck
Ryan
