NO real EZ way to lower pressure on an A engine(like on a B-engine) ... but the benefits are not only saved HP on running the pump less ... but also less oil flying around hitting the crank and rods PLUS less oil on the cyl walls.

For the type of driving it wounds like this vehicle will be doing he will NEVER notice any difference.



His type of driving ? .. it is a race car. Now if he does not care about his ET ... I will stand corrected.

He states this: "I get an occasional
6000 run, but not much above that often, and not
for extended time."
So go figure. that kind of pressures he won't make a noticeable difference. People are racing and driving with that kind of pressure all the time. In the real world there are a lot more variables that will come into play that will change things a heck of lot sooner than that. Including driving consistancy.
On a good warm day you will be glad that you have a little extra to work with. that pressure will take care of itself and is not excessive to the point of being harmful. Nor will the pressures in this case contribute to a gasket or filter blowing out if quality parts and careful assembly proceedures have been used.
