OK. I know people that race vintage and historic sports cars. They did all sorts of tricks with oil delivery and reducing friction/drag. Things like spraying a mist from the crankshaft to lubricate the pistons/rings but not so heavy as to cause drag in movement. Probably not things in a stock motor.
Full tube race chassis. Fiberglass shell or body. $15k in a race engine (in the late 80's and early 90's). Dry sump oil system.
600+ hp in a 355 cu in, normally aspirated engine.
