what is the best way to change the manifords on a 1987 ford van. The is a 460cu or 7.5L motor. chesley

 

One vacuum hose, and one bolt at a time. Better you than me. I hate vans.

 

first off buy an aluminum replacement.... you will apreciate that when you put it back on!! The stocker is heavy It shouldn't be to bad when you have the inside engine cover removed and the hood open.
