Ford Van Lift

Ford Van Lift
Can you use lift blocks to raise the front of a truck/van?

I have a Ford clubwagon 1990, it the same as an E-350 and I want to give it a 4 or 5″ lift both rear and front, some people have told me its ok to use a block in the front, others say not to…so I am confused.

homer_being, I bought a used Is 350 in North Dakota last week and saved a lot. I haven’t had any problems yet. I only buy used cars. http://www.findusedcardealer.com
