Thanks Bob,

Your insight to fluid dynamics is enjoyable to me, as well as others I assume. The most common myths I have heard from other hot rodders reguarding oiling systems in V-8's are Smokey's rule: 10 psi per 1000 rpm recomended oil pressure, and the greatness of high volume pumps. I will stick with smokey's rule, but only up to a point, after 45 psi what's the point of more pressure.(assuming you aren't running nitromethane or something) I also have a strong dislike for high volume oil pumps. One ruined a BBC I used to own. Above 4500 rpm, the pump would suck enough oil to cause a vortex in the oil pan and then it could suck up air. Oil pressure would drop at high rpms, but only noticable after I bought a quick response gauge and plumbed it with -4 line instead of the nylon 1/8" stuff they give you with gauges. Either way, I would rather learn about lubrication by discussion than by replacing parts and trying to figure out why they failed.
