as it sounds like from above is your only option.. (true?) and space is tight enough that you need to be able to move the car.. put the trans and motor in together (you WILL need an engine tilter for this) - this way you'll be able to push the car back and forth to make room for the hoist, motor and trans. Properly tilted and adjusted as you go, the motor and trans will slide in slicker than whale snot.. what everyone else has said about removing the headers, distributor, carburetor and radiator is true. Also, I too have found it best to “pre-install” the headers in the engine bay and held back as previously suggested in this thread…
