This high volume oil pump is thicker than the production LS1, LS6, LS2 and LS3 oil pump and may not fit in a stock timing cover with aftermarket double roller timing chains that require spacing out the oil pump.
The Lingenfelter high volume GM Gen III & IV V8 oil pump is recommended for use in applications that will require increased pump flow to achieve the desired oil pressure. Engines with piston oil cooling jets, radiused crank bearings, aftermarket lifters or increased build clearances may require a higher volume pump to achieve the same oil pressure, especially at low engine speeds and higher oil temperatures when the pressure relief valve is not in control of oil pressure.
This oil pump is supplied with a standard pressure relief spring installed in the pumps pressure relief valve. This spring is yellow in color. For most applications this is the spring that LPE recommends you use. For cylinder deactivation equipped engines you will want to use the higher pressure relief spring. If a higher oil pressure is desired, remove the yellow spring and replace it with the supplied orange spring. The orange spring will provide a roughly 10 psi increase in peak oil pressure. With the installed standard pressure yellow spring, the pressure relief valve should start to open at 33 psi and be in full relief at 65 psi while with the high pressure orange spring the relief valve should start to open at 43 psi and will be in full relief by 75 psi.
