Bill, Yes Olds did. The problem that Joe dealt with was one of our own
creation. When the Olds is fitted with a high volume oil pump, certain high
rpm operations will deplete the supply of oil in the STOCK OIL PAN. That
led to restrictors in the oil galleries as an attempt to reduce the flow
rate and as a secondary benefit?, an increase in pressure. Jury is still
out on that as a benefit. It is kind of a yes-but deal. I question the
value in a motor home application. Absolutely bone stock 455 and 403 Olds,
in heavy vehicle operation, with proper oil change intervals and tune ups,
easily last well over 100,000 miles. A lot longer in lighter vehicles. Do
we really NEED high volume oil pumps? I lean towards the not really, but,
group of opinions. But, gee let's re gear this sucker, put some headers on
it, stack on different intakes and camshafts, add on fuel injection, etc.
and the equation changes quite a bit. You rev these suckers up (like Joe
Mondello) or you and me in, for example, a jet boat or street rod? Any
weak spots in an engine design will quickly surface. Then we have a
tendency to attempt to "bullet proof" an engine so it will live in
circumstances of our own creation. That is some of what Joe did. Your
opinions might vary.
