S10 V8 Truck 4x4 Oil Pans & Parts
The stock car or truck V8 oil pan will not clear the front axle/differential
on the 4x4 V8 swap. A special oil pan is required on the 4x4.
Stealth Conversions has offered three oil pans for the 4x4 V8 swap. Currently, only the 4x4 DO-IT-YOURSELF PAN EXTENSION S10-113 is in stock.
- Part # S10-110 (shown above) which fits 1979 and older engines (and has a dipstick tube mounted on the driver’s side). The dipstick tube is included with the pan, which is why this pan costs more than the other pans.
- Part # S10-111. Fits 1986 and newer engines with the one-piece rear main seal and passenger’s side dipstick. This pan uses the stock block-mounted dipstick tube.
- Part # S10-113. This is the do-it-yourself version that requires welding an extension onto the stock oil pan. Fits 1986 and newer engines with the one-piece rear main seal and passenger’s side dipstick. This pan uses the stock block-mounted dipstick tube.
- Part #S10-115. Fits 1980-1985 oil pans with the 2-piece rear main seal, and the passenger’s side dipstick. This pan uses the stock block-mounted dipstick tube.
The pans are made from dry-sump racing pans and will accommodate a stroker crank. The chamfered cut-out on the driver’s side provides clearance between the front-differential and the oil pan, so the engine can be mounted low enough for proper transmission tunnel clearance and hood clearance, without the need for a body lift. The deep sump holds 5 quarts of oil and allows using the offset-oil-filter-adapter instead of a remote oil filter.
Some of the V8 4X4 oil pans currently on the market do not have the chamfered cut-out feature, which requires the engine to be mounted higher than with the Stealth Conversions oil pan. The non-chamfered pans require more transmission tunnel modifications, and the higher height can cause hood clearance problems with the large diameter engine-driven fan required for adequate cooling. Also, the offset-oil-filter adapter may not fit other brands of S-10 4X4 V8 oil pans.

4X4 PICK-UP TUBES
The 4x4 V8 oil pan shown at the top of this page has a sump that is about 3" deeper than the 2WD sump. The oil-pump pick up tubes must be replaced with the units shown above.
The oil pans sold be Stealth Conversions include the pick-up tubes shown above. The pick-up tubes have a bracket which bolts to the oil pump to positively secure the pick-up in place without the need to weld the tube to the pump.
Generally, 1995 and older small-block engines use a 5/8" oil pump pick-up tube (shown on the left), and 1996 and newer small block engines use a 3/4" pick-up tube.

Oil Pan Pickup Tubes for Do-It-Yourself Oil Pan
The oil pickup tube on the left is the standard V8 part that is found in a Camaro, Caprice, or 2WD full-size pick-up.
The oil pickup tube on the right (GM part #14054836) must be installed when using the 4.3 V6 style sump for the 4X4 V8 conversion. It is the same oil pick-up tube that is used in the 2.8 and 4.3 V6 4X4 S-Truck. It must be used with the deep sump 4X4 oil pan or the engine will suck air and die.
Although the 4.3 V6 4X4 sump is 2-1/4" deeper than the 2WD sump, it is shorter (front to back), and does not have more oil capacity. The sump shown on the previous page holds 4 quarts.
