IMPORTANT: It is advisable to wash all of the new parts well before installing to remove any dirt or debris from the packing
and shipping process.
IMPORTANT: It is advisable to test-fit the oil pan to the engine before installation to ensure that the crankshaft and
connecting rods clear the windage tray, oil pump pick-up screen, and the oil pan, making a full revolution of
the rotating assembly by hand.
IMPORTANT: It is advisable to mock up the engine and oil pan in the intended vehicle to ensure there is no contact of the
pan to the frame or cross-members.
INSTALLATION:
1. Remove the new Holley® oil pan, parts kit, pickup screen and baffle from the box.
2. Install the supplied o-ring onto the oil pump pickup screen assembly and lubricate with clean engine oil (Figure 3).

P/N 302-1 OIL PAN:
WARNING! Due to the design of the Holley® oil pump pickup screen, slight modifications may have to be made to the oil deflector
before the pickup screen will sit flush (Figures 4 & 5). Be sure to inspect this area before bolting the pickup screen into
place as modifications may have to be made. GM offers an oil deflector that has the necessary clearance for the mounting
bracket of the pickup screen. The GM P/N is 12611129, if modifications to the oil deflector are not desired.
