i am verry familiar with this motor, i know it inside and out. the 1987 makes 205 horses with its throttle body injection. the 1986 k5 blazer made 210 horses with its 4 bbl carb.
about 265hp roughly for a stock motor
I believe it's about 28 horsepower.
Depending on which engine it has, horsepower could range from 300HP to 435HP.
