super six horsepower ratings and specs...

Take .090 off the head, and get yourself a cam that works well with the increased compression and improved breathing that a header and a 4bbl offers. Then youll be on your way. Head porting would be next along with larger valves, then forced induction.. Make a plan early and stick to it, dont waver off your plan because a mismatched part is a "bargain" we have all done that at one time. Turbo is a leapfrog path to instant horsepower on an otherwise stock motor, but it takes a little research and a lot of fabrication. First thing you may want to try is a taller rear end. 2.76 on 140hp/215 ft/lbs torque is nothing to drag with, 3.55's would be a huge upgrade on perceived power.
