1978 GMC K25 Oil Pans

you have probably heard many a horror story about someone losing an engine when the oil pump fell off into the pan because of a broken bolt. Well, you can put your mind at ease when using ARP premium grade oil pump bolt and stud kits. You have a choice of black oxide finished 8740 chrome moly steel or low maintenance stainless steel. Both are nominally rated at 170,000 PSI tensile strength to provide you with plenty of clamping force. Moreover, take your pick between conventional hex style or 12 point designs. This is insurance that no conscientious engine builder should be without The studs come with flat washers and nuts, while the Ford bolt kit has flat washers only. These inexpensive fasteners can literally save your engine.

This engine oil pan is precision-engineered to match the original equipment pan on specific vehicle years, makes and models for a reliable replacement.

GM’s popular LS engines find their way into a huge variety of vehicles. Unfortunately, the factory LS pans don’t always fit in the vehicles we would like. Holley’s new LS 4WD Off-Road Engine Swap Oil Pan is designed to help. It provides maximum clearance to the chassis and drivetrain for the K10 chassis and other LS swapped 4WD applications, plus provides an OE (Original Equipment) Style fitment for durability and proper sealing. In addition, the 302-4 and 302-4BK are compatible with all popular transmissions (SM465, NV4500, TH350, TH400, 700R4, 4L60-4L70, 4L80, 6L80 and 6L90).

Holley also offers an optional off-road hinged door baffle (No. 302-33 for LS engines and No. 302-34 for LT engines) and rock shield (No. 302-35) that can be added at any time to further protect your investment.

Holley’s popular cast aluminum oil pan (P/N 302-4 and 302-4BK) designed to swap LS engines into K10s and other trucks has just been brought to the next level. Vehicles that endure prolonged sessions of climbing, crawling, braking, turning, and accelerating need extra protection from oil starvation. That’s where the 302-33 oil pan baffle kit comes in. This oil pan baffle kit improves upon the baffle included with those pans as the 302-33 is designed to maintain proper oil level at the oil pump pick-up during vehicle elevation and grade changes, accelerations, both lateral and linear, and braking. The baffle maintains the oil at the oil pump pick-up preventing loss of engine oil pressure during off-road excursions as well as under hard acceleration.
