My buddy has a DZ in a stock Z28 69 camaro. It is all top end, good rpm's, torque is not is finest attribute for sure... has to spin the tires to get a decent launch, but it is all stock w/ the solid cam & 373's. Neat motor, but needs low-end assistance (his car is 4spd). It is a dog until about 4500RPM then it gets it.
