Heres a new question and possibly a new approach to answering all of our questions. When you look inside the oil pan with the two large "gussets", it has a baffle on the lowest step and it looks as if GM put these gussets and the baffle there to keep oil from coming out of the bottom step where the oil pump would sit, like if the nose of the car was aiming down or on a high sweeping turn the oil would not drain out of the bottom step as easy. Wouldn't a totally flat middle step allow oil to move away from the pump easier? Maybe what GM was trying to accomplish then is what was later accomplished with a trap door? There had to be a reason for these gussets and I would definetely think it would be for performance reasons. FORGET ABOUT THE BOOKS FOR NOW, LOOK AT THE PAN AND TRY TO FIGURE OUT THE FUNCTION FROM AN ENGINEERING STANDPOINT.

Re: New Question On The 58' Oil Pan
I think it's pretty well known there were different configurations of oil pans... Some versions had no baffles, some had a fixed baffle (as you describe) and others had a dynamic baffle (swinging trap door). The baffle added cost/complexity to the assy and those with a dymanic baffle were slightly more costly/complex than the pan with fixed baffle provision.
The key is what was used where/when and that's a matter of engine assy plant records, by suffix code/by time and drawing revision history which the AIM and service records don't address...- Top

Re: New Question On The 58' Oil Pan
The oil pan that is on my '58 along with another identical one that I own both have the fixed baffles and gussets. The gussets look as if they are pushing the oil to the bottom of the pan or slowing the oil from leaving the bottom. These pans with baffles and gussets must have a function to warrant the extra expense involved in making them as you mentioned above. If we can restore these cars then surely we can sit down, look at the inside of these pans and figure out why they were designed the way that they are. They just look to me like they were designed with a purpose which would have been oil starvation under extreme operating conditions.- Top

Re: New Question On The 58' Oil Pan
Roy, I think sending me back to the earlier post is a little confusing, There are close to 50 posts now. One says one thing, one says another. I just want someone to tell me what the intended purpose was to have the gussets stamped in and also a baffle. It had to be designed this way for a reason, right? If you look in this particular pan, what would be your best guess for all of these details?- Top
