350 oil pan vs 455
#2
The baffle helps keep oil around the pickup, which is always a good thing. There's no downside to using the BBO pan on an SBO, except that it won't be optically correct for a totally concourse restoration. The BBO pan has two "bulges" at the front of the sump to allow space for the baffle to be spot-welded into place.

Isn't the 455 pan a more gradual shape also, so it can hold more oil? At least, IIRC (20 years ago?!) the OE 350 pan has an extremely square sump. No need for a baffle since the front wall is vertical, but you lose a bit of capacity without the slope.

I like big block baffled pan on the small blocks and the "horsepower robbing" Toronado pan on big blocks but with the small windage tray and the front timing "block off" baffle. I like the extra quart of oil. Jmo.

I,m not really going for a concourse restoration and can’t seem to find a good used big block pan for a decent price or one even close to me that won’t cost a lot for freight, has anyone used the aftermarket pans that are supposedly stock replacements but the drain plug is one the side corner of the pan vs the bottom originals? I do have a original small block pan that’s in good condition that I could use just don’t know if there would be any issues vs the baffled pan, will the non baffled pan keep enough oil for the pickup screen? I am running a HV pump but also restricted pushrods and the main bearings holes have been drilled. Not really building for racing so don’t know why I bought a HV pump mainly just use it for car shows a cruising around, may hit the drag strip once and awhile.
