How do I remove a oil pan from a 1968 Impala (327ci)?

We got the oil pan bolts removed, but can't get it out of place. Any suggestions or tips?How do I remove a oil pan from a 1968 Impala (327ci)?
To elaberate on what was said. IF you do not have a crossmember or steering arm in the way, then you are more than likely catching on the Crankshaft (it comes down about 3 inches into the oil pan) - or you are catching on the oil pump pickup tube (it comes down almost 5 inchs into the oil pan)





You MUST lift the motor high enough that the pan will come DOWN to clear these items - WARNING if you move the pickup tube on the oil pump / or bend it / you will NOT get oil when you re-start the car - that pickup tube sets just above the bottom of the oil pan - about 1/2 inches from the bottom.


WARNING - if you do not watch what you are doing you will break the distributor on the fire wall, or break the exhaust from bending them, or break the transmission from the lift.

You do not indicate why you can't get the oil pan off, but there are typically one of two problems and I will address both.





The first is that there is an obstruction in the way, often a steering arm or the like. If that is the case, that too must be removed.





The other is that it simply will not budge, as if it is glued on, which in a manner of speaking it often is. Often when an oil pan is installed either a sealant has been used, or it has remained on so long that the gasket has more or less fused between the engine surface and the lip of the pan.





In either event, there are two methods commonly used to freeing it. You can use a large rubber mallet to strike it from various angles (being careful not to hit is so hard that you bend it) or you can put a piece of 2x4 or heavy plywood on the side to spread out the stress and cushion it a bit as you use a hand held sledge hammer (somewhat less vigorously) for the same purpose. Your blows should be directed at the low hanging corners of the pan, as there it is not only structurally the most sound, but being farthest from the sealing seam it will exert the most leverage.





You can also try to work a putty knife into the seam and work your way around once you get a gap started. I would avoid using a chisel for this purpose as, if you are not careful you could gouge a place into the sealing surface and thereafter you will not get a good seal.
