Holley® Performance Products has written this instruction sheet for the installation of the LS Retro-fit Oil Pan. This instruction sheet

contains all the information needed to install the oil pan. Please read all the WARNINGS and NOTES, as they contain valuable

information that can save you time and money. Holley® Performance Products cannot and will not be responsible for any alleged or

actual engine or other damage, or other conditions resulting from misapplication of the oil pan described herein. However, it is our intent

to provide the best possible products for our customer; products that perform properly and satisfy your expectations.

APPLICATIONS:

302-1 – The Holley® P/N 302-1 LS Retro-fit oil pan is designed for LS engine retrofit installation in a wide range of popular GM

muscle/classic car and truck chassis.

302-2 – The Holley® P/N 302-2 LS Gen 1 F-Body Retro-fit oil pan is designed specifically for LS engine retrofit installation in 1967-69

Camaro/Firebird (Gen 1 F-body), 1968-1974 Nova/Apollo/Omega/Ventura (Gen 1 X-body) vehicles. The 302-2 oil pan may

also service other popular muscle/classic car and truck chassis where more engine-to-chassis clearance is required near the

front half of the oil pan.

IMPORTANT APPLICATION NOTES:

 Both oil pans provide OEM fitment and oil filter mounting provisions.

 302-1 & 302-2 are not intended to be used with engines that originally utilized a dry sump system.

 302-1 is designed to use a GM full length windage tray. Depending on which full-length windage tray is used, some

modification to the tray may be required. See the instructions showing the modification which may be required.

 302-2 is designed to use a GM “F-body” windage tray, GM P/N 12558253. A modification to the windage tray is required to

provide clearance to the pick-up tube. A full-length windage tray may be used if the front quarter of the tray is removed. See

the instructions showing the windage tray modifications required.

 302-2 may not be used on LS7 engines or engines with a stroke longer than 3.62”. The internal rotating assembly to oil pan

clearance provided in the front half of the oil pan is patterned after a GM 98-02 LS1 oil pan.

The Holley® LS Swap oil pans are designed to work with an LS3 dipstick and tube (if desired). Below are the part numbers:

 LS Dipstick – GM P/N 12634547

 LS tube – GM P/N 12625031

NOTE: There are LS engine applications that have a plug installed in the dipstick hole location to be used with this oil pan. This plug

will need to be removed before the oil pan is installed on the engine to allow the installation of the proper dipstick tube.
