If you are doing this in hopes of saving gas. You may do the oposet, because the 4.3L would have to try harder to haul around such a heavy van. also the 4.3L doesn't get much better mpg than the 5.0L even though it's in a lighter blazer/astro.

Think of it this way if you add 500lbs to the back of a blazer and see how good the gas mileage is then.

let me know what you think or find out.

good luck

I run a 94' G20 with the 4.3 vortec, I have a 130000 miles on it. Runs fantastic. It's not a speed demon off the line. It will go 100+ MPH if you need it to. I have the 4 speed od and I get about 17 in city and 23 hi-way. and mine is a conversion van so it is heavy.
