lol you can have your 2 hours, i can have the motor and tranny out then tranny disconnected in just over 1 hour doing it out the bottom if i haul butt, if i take my time its still less than 2. Its just soo much easier out the bottom, it would still apply also if you had a/c, you dont have to worry about the lines, unbolt the compressor and drop it down, i have done a whole engine swap without the use of a cherry picker. haha
To remove i just used my jack with a board, then lowered it and slid it out, to get the new one in was a little more tricky, but what i did was after i slid the motor under the car i used the jack to lower the car basicly onto the frame which is as low as the jack would go, then slid the motor over into place on the passenger mount, then slowly raised the car with the jack and it took to motor up with it, also i didnt have the tranny on yet during this swap, the crank pulley will rest on the side of the frame and it will eventually go up with the motor, I put the car back onto stands then just continued to bolt everything up like normal, putting the tranny up and everything else. worked like a charm but it took more time obviously. But i now have a new cherry picker so its all good
