I know a guy that is really big into hot rods. He's got a late 80's model firebird with a custom engine in it. Dudes got probably got between $15-20k in the engine alone. It puts out somewhere just over 1000 hp, and he's done all the work on his own, so I feel inclined to believe the guy. But I really want to know how this makes sense as he didnt offer much explanation. He says a lower oil pressure is better as far as performance goes, because with the higher pressure, the higher youre putting it up in the block essentially. Which if I understand correctly, means you would be putting a lot of oil on the valves, springs, rockers, etc. whereas with lower pressure you would be keeping the oil lower on the cam, pushrods, etc. is this the case? and if so how does this positively or negatively effect the performance of the engine?
