Paul and group,
The Oil line size is not a big deal unless you have a system that

could require

full flow. That wouldn't be common in a semi-closed loop system like

our engines.

I'm not quite sure what you mean; but my dyno runs  (20B) show 15gpm oil
flow at 6000 rpm; and unless your lines are real short that amount of
oil flow in a -8 can make for a significant pressure drop.  Sure; you
have the pressure available to drive it, but the pressure drop will
decrease pump efficiency, or cause bypass at the pressure relief valve.
The issue, of course, is not oil flow for the engine, but heat
rejection.

I'll put some pressure gages on both ends of the dash 8 on the dyno engine
and measure the drop.
