Click the North east regional forum. There are A lot of guys from PA on that website and i know would be willing to lend a hand for a case of beer or something small like that.

Support the motor, un bolts upper motor mount and trans mounts and drop the whole subframe onto the ground. Use the picker and hoist the car up in the air high enough to slide the motor out the bottom and then unbolt from power steering and trans mission. Then bolt the new motor back in.
Or if you think you can handle it, you can do it with the trans still in the car and just pull the motor but its more of a bitch that way.
