A few days ago I was moving some of my stash of parts around and figured I would post some pictures of differences of olds BB and SB oil pans.
And yes they they are not clean I do it for a reason.
First picture, top pan is a BBO bottom is a SBO. I dont have a Toro pan so it won't be mentioned. There is a baffle in the BBO pan and none in the SBO pan. Purpose of the baffle is to keep the oil from going towards the front of the pan and sucking air on deceleration .
Second picture you can see a big difference between both pans, top BBO bottom SBO. The BBO pan is a little deeper before the sump to accommodate the bigger BBO crankshaft and prevent whipping of the oil. If you're building SBO use a BBO pan it has advantages, you gain almost a full extra quart that is almost 6 quarts of oil with filter and ground clearance. Your dip stick will say its over but your fine.
