I rebuilt my 1959 Ford FE 352 engine last year. I opted for a melling standard output oil pump and standard bearing clearances. Thus engine has hydraulic flat tappet lifters. I've run Amsoil Z-Rod 10w-30 but I have alarmingly low oil pressure, 10psi hot idle, and 25psi going down the road at 2000 RPM. Oil pressure is measured at the oil filter adapter which is obviously the closest to the oil pump. Cold pressures are 45psi 650RPM idle, and 60psi at 2000.
I wish the oil pan were easier to remove and I'd simply install a high volume oil pump, but that is a bit of a challenge while the engine is in the car due to very tight cross member clearances.
Is the Z-Rod 10w-40 much thicker, or should I opt for the wicked expensive 20w-50?
I'm not completely sold on using a boutique oil for this application, I just have an Amsoil account and put 6 qts of Z-Rod on my last order. I'm open to other options. I could just Rotella 15w-40 or something similar. I put roughly 2000 miles a year on it, and was planning on a biannual oil change with the Z-Rod, but could do something else.
What do you guys recommend? This thing isn't a hot rod and will never see over 4000 RPM.
