my 87 k-5 blazer stalls and backfires on take-off but runs good when you get up to about 20 miles an hour

Check for vacuum leaks around the intake. Make sure fuel pressure is within spec and the regulator is working properly. A common problem was the intake gasket. So check that closely... expecially around the rear of it.
