Isn't restricting the
oil to upper end a bad idea for a "street" engine which WILL be idling for a while under normal usage?
I know a total "race" engine can benefit from this mod but for street, people that know WAY more than me always said just do a "opening" of the returns, this will get the excess
oil back into the pan quicker... It's also a given to use a high cap. pan on either street or race engines...
Am I wrong?
