how can i find out what the top speed of a ford e150 van is from 1993 gas powered 8 cylinder?

 

I would recommend taking it out on a deserted freeway and sticking your foot in it until it won't go any faster and look at the speedometer! Works for me! But, seriously, my 1993 Winnebago conversion van with a 302 in it tops out at 90-92mph with the tall roof on it. I think that little 302 is pumping its heart out to do that, but that was about 5 years and 40,000 miles ago so I doubt that it will still do that but I am going to give it a "heart transplant" soon and it will probably do a little better then.
