I've done a few (Ford 360/'68 F-100 pickup, Ford 351W/'78 F-100, two older SB Chevys, 1.6 Honda motor in the car)-my desire to get incredibly dirty, engine parts everywhere in the garage, and a vehicle out of service for a month have all declined as I've gotten older. If I had a big pole barn, a lift, and more room I would probably try it on a project car, but not a DD.
