You evidently had one he*l of a big tree.
Watch carefully that Road Race oil pan if you attempt to torque bolts to recommended 15 pounds. You will severely dimple it,,depending on gasket you use.
I ended up building a girdle that encircles the pan of 1/8th thick stock steel that goes between pan and bolt heads. Highly recommended. I believe that someone is now selling a kit.
Do this right, you should not need any of the silicone sealers that inhibits the removal next time.
do you know where these kits are sold? I'd love to get one, I've already had to remove my pan 3 times since I got it and the silicone is a PITA to remove, also why hasn't milodon made a reuseable gasket for the big block yet? they have them for the small block...
