Not sure if this is relevant to all but we needed to drop the engine down an inch or two to get the old one off due to clearence issues.
Also we used the stock crank bolt hopefully nothing falls off.
Anyway, heating it to about 450 degrees for 20-30 min did wonders on ours but may not work as good on some. (A/FX UDP)
