can you slide the trans back at all? if so, how far? if you can slide it back, have you tried to turn the engine with it slid back? i've pulled tranys with the internals welded together from being smoked so bad, and still been able to turn the engine to get the convertor bolts out. this may be a long shot, but you may be able to get to at least 2 of the convertor bolts. pull the crossover pipe to give you a little more room. break the two bolts that you can get to. jam a big pair of vise grips on the flywheel. with only one bolt remaining, it should flex enough to give you a c.u.n.t hair of movement. a little less aggressive than cutting the bellhousing!! if you still can't move anything, then the motor's probably locked up, unless you have arms like olive oil! btw, did you pull ALL of the plugs? even one cylinder that's hydrolocked won't budge at all. good luck and let me know how you make out.
