Not apples to apples...You have a CJ ...cam has more overlap...More carb.... Larger runners in the intake and I would Guess 3.90 gears and More Cubes and larger valves....very far from a STOCK 352 or 390

You have the fun factor when you hit the loud pedal right ??

That was Never intended to be a Economy engine
