225 oil pan modifications

Depends on the design, the 235 Chevy Stove Bolt was exclusively splashed oiled for a number of years. And wasn't changed over to pressure feed until the mid '50s. Uncle Tony has a video on why nitro cars used to use 3 gallons of oil. The increased oil capacity was used to dampen the harmonics of the combustion process. The crank was bathed in the oil.

I asked on .org just how much splash oiling was needed by the \6. I never got a satisfactory answer.
