To make a long story very very short, how long do you think it would take to perform an engine transplant on a 1987 Carrera 3.2? The entire drive train (engine, transmission and muffler) is out of the car.

A little explanation: due to a series of unfortunate encounters with under-qualified mechanics, the engine, transmission and muffler are currently out of the car. I was shopping around various garages and was wondering if anyone could provide me with an estimate for the rough time needed to install an engine, transmission and muffler.

Thanks!
