Worst enemy?

Ah first off drop engine and cradle out the bottom then start on the rest of the mess ! Done a couple of those but just leaking timing covers.
That would be great, but when I sold my house the shop went with it. Did it all in the car. Thermostat, water pump, belt, tensioner, idler, chains and sprockets, rear shocks, O2's, upper and lower hoses, battery, blah, blah, blah. I don't want to do it again. My only concern is when I get it back together it won't run. I'm not sure how much of its memory it will lose.
