You need something to keep the motor from spinning. From my experience, those HB bolts are stuck, and in impact wrench won't cut it (Cambell pnuematic 1/2'' drive, 110 psi or so). I've heard of the flywheel cover (black plastic on the bottom of the engine) being taken off and sticking a piece of metal or maybe wood between it and the ground to keep it from spinning. I think dealers use a flywheel holder tool of some sort, if you have access to one.
Other alternative would be to use a 48'' pipe wrench around the flippin HB to hold it. We're a family of plumbers, so most of you guys may not have access to one
. But if you know a plumber...
Does like Home Depot rent those out?
