Setting ride height/alignment with no motor

i dont know about any one else, but EVERY /6 to 440 i have pulled out and installed has resulted in the front end of the car changing ride height at least 2-4 inches. i find it pointless to set the ride height before dropping in a 700 pound engine plus a transmission

Sure, that's why you'd need to crank down the bars and set the ride height without the weight in the car.
