I have a dolly that was made to roll engines around on. I guess its about 18x18 or so. It has slide rails that line up with the bolts on the bottom of the oil pan rail. The oil pan is about 6" off the floor when on the dolly. Once the long-block is completed I can attach the k frame with the steering box, the idler arm and drag link. I bolt up the trans and converter along with the trans mount. Bolt on the starter and headers,followed by all of the kickdown linkage, starter lead and trany lines. I use the engine crane with a pipe under the front frame rails between the bumper brackets to lift the front end. Rear wheels are on the ground. You can roll the whole assembly in from the side only lifting the car high enough to clear the distributor under where the upper control arm bolts on. Lower the car slowly and the trans mount gets the four bolts installed. Lower it down further and install the 4 k frame bolts. Slide the LCA's with the strut rods in and hook up the torsion bars. UCA's are already on car with spindles and rotors attached. You don't have to re-bleed the brakes this way. Bolt the front shocks up and install the steering column and linkages or shift cables. Pop in the driveshaft and your all but done underneath. Worked great on my 70 Satellite with a 383-727. I hope it works equally as well in a couple weeks with a 340-727 in the 69 Dart.
