the 4.2 staight 6 has lots of low end torque and good horsepower. It is a big engine. 3 inches longer than ls1
Rumor has it, they have 270 hp at the flywheel. My wifes trailblazer has the I6 and it gets up ok. Not a speed demon. For the money and time to fab up the garb for it you might be better off with the 4.3v motor, or even better the LS motor.
