Do any of you Motorheads know how many different stock oil pans were available for the 351 Cleveland during its early 1970’s production run?  I just finished all the work to remove the oil pan with the engine in the car because of a rear main seal leak, removable cross member, removable e-brake bracket, etc... (good time to replace the shifter trunion since I had to undo it for the pan to clear). Once I got the oil pan off I was happy to see a 4 bolt main and the oil pan has baffling. Could this be a stock pan from a Boss or Cobra jet?  Thanks for any info!

My stock pan was the same.  Note that it's not really "baffled" in the sense of a true baffled road race pan, which has trap doors in the baffles that only allow oil to flow toward the pickup, not away from it. I spun a rod bearing with my stock pan while taking a tight hairpin turn at WOT in 2nd gear. All the oil ran up the wall on one side of the pan leaving the pickup dry.

Here are a couple pics of my 10 qt. Armando baffled road race oil pan that's on the engine now.

You can just see the hinged baffle beneath the windage tray in this pic.IMG_4403

Garth, out of curiosity, when you were WOT in 2nd gear, what rpm were you at when you spun the bearing?

Hi Joe,

I'm not sure. I was stuck behind an idiot in a minivan slowly cruising up a twisty mountain road who refused to take any of the turnouts! Finally came to a right-hand hairpin turn that had a turnout lane on the inside, so I took the inside line through the turnout. Coming out of it as I was about to go for 3rd gear, the engine suddenly sounded like someone was violently shaking a tin can with ball bearings in it. I immediately let off the throttle and the noise settled down, but the damage was done.  The oil all went to the left side of the pan and climbed the wall of the pan and left the pickup dry.  I don't think I revved it over 5,500 RPM, but I wasn't watching the tach.

To answer the OP, there were three different 351C oil pans. One was a simple open bucket. #2 was the same pan with a sheet metal baffle down in the lowest point to serve as a "baffle" around the pump pickup screen. #3 was the same pan again with the sump baffle plus a rudimentary scraper on the sloping part of the upper pan. This is the so-called 'Boss" pan and is what shown in the photo. Some are date-stamped on the outside of the pan bottom.

All three stock pans are dangerously inadequate on a Pantera, because of its cornering capabilities even with stock tires. Quite a few owners have lost engines with full stock pans due to oil moving away from the pump pickup on acceleration or cornering. If you drive the car as it was meant to be, you WILL spin a bearing and/or launch a rod. An Aviaid pan, or one from Armando (who worked for Aviaid, then started his own shop) is cheap insurance compared to replacing a block.
