I have the Precision Pumps high volume
oil pump on my Fe406. I am in the process of building a '63 427 center oiler and plan on putting that pump on it. Anyway, I bought the HV pump for the 427 but decided to install it on the 406 while I was building the 427. The
oil pressure on the 406 pre HV pump was what I would consider low. When hot the pressure was around 10-15 lbs at idle and 35-40 lbs at 3000 rpm. Now with the HV pump the pressure is around 25 lbs at idle and 80 lbs at 3000 rpm. When the engine is cold, I am careful not to rev it too high because the idle pressure is around 80 lbs and it goes over 100 if revved too high. So I am happy with the new pump.
"Doug" at Precision Pumps seemed like a very nice guy to deal with and he did exactly what he said he would do. eg shipping times, product etc. I was very satisfied with their service. He sells other stuff for the FE as well. Check out their web site.
