i hear different opinions on high volume
oil pumps, some people say they are used on race motors when they are using loose clearances, they use horse power and put stress on the drive and cam gear. now what about a high pressure
oil pump do they rob horse power or put stress on the
oil pump drives?. i am trying to decide on wich pump to use in my 390 stroker i will be using a baffled oil pan also. any thoughts on this subject?
