4 bolt mains and big crank... can u pull oil pan?

Ok I just spent all yesterday trying to pull my oil pan, ended up putting my oil pump intake tube back in, and starting her up. It turns out we must have bent the damn oil pan so much that it is hitting a crank journal now. Does anyone know an easy way to pull out the oil pan? I had the jack up as high as it can go w/out the intake hitting the firewall and the motor mounts off, and its still wouldnt wiggle its way out like it did stock. any help appreciated.

If the oil pan came out where you're at now when it was stock; I'd assume your hitting the crank. Did you try rotating the crank?

havent tried moving the crank, back wheels are on the ground. I can try and see if that works, but once one crank is out of the way another one gets back in the way... worth a try though because it seems its only 2 crank journals grabbing... anything else?

i was thinking about this the other day when i saw my headsers were bent from hitting somehting, like in body work when they pull a dent they weld a nail to the metal and use a slide hammer to pull it back out, i wonder if it would work on this, or the headsers i was thinking of?

how did you bend the pan?

how did I bend the pan..........I wont really get into that, lets just say that it is bent around crank journal 2 (from front of motor) and visibly at that. I am about to drop the k-member to the bottom of the threads and see if that is enough clearance, anyone ever do this and run into problems?

Also, with putting the transmission in neutral, I was thinking about this, but the problem is I still have the belt and all the topend of the motor assembled. If I where to turn the crank manually I was hoping to do it with the rear axles because I didnt want to take the crank pulley off and use the bolt... I guess this is still possible though, how much clearance can be obtained by turning the crank honestly? I mean it is stuck in there almost on the 4 bolt mains and my transmission is what it seems like to me, other people aresaying the crank, but its so hard to tell down there. With the K-member dropped a good 1/2" I should have plenty of clearance for that.

thanks again
