1969 Pontiac 350 Oil Capacity Specifications


Pontiac's 350 engine was introduced for the 1968 model year, replacing the company's 326. It is an overhead-valve V-8 with a bore of 3.88 inches and stroke of 3.75 inches, giving it a displacement of almost 355 cubic inches (5.8 liters), despite the fact that it is known as a 350. You will usually find it under the hoods of Tempests and Firebirds, though it was also an option on other Pontiacs in 1969.

Engine Specs

  • For 1969, Pontiac offered the 350 in three versions. The standard version uses a 9.2-to-1 compression ratio and features a Rochester two-barrel carburetor. It produces 265 horsepower (hp). A high-output ("HO") version runs with 10.5-to-1 compression and uses a four-barrel Rochester carburetor to make 325 hp. A second HO version, using the same carburetor, produces 330 hp.

Oil Capacity and Other Capacities

  • The 350 engine's crankcase holds 5 quarts of oil, plus another quart for the oil filter. The amount of coolant used depends on the car. For the 1969 Pontiac Tempest, you should use 20 quarts, or 21.25 quarts if the car is equipped with factory air conditioning. For the Firebird, 19.5 quarts are called for, unless the car has air conditioning, in which case 20.25 quarts is the right amount.

Ignition Specs

  • The '69 350 engine uses AC R45S spark plugs. The spark plug gap should be 0.035 inch, and plugs should be tightened to 23 foot-pounds of torque. The distributor point gap should be 0.016 inch; cam angle should be 28 to 32 degrees. Cylinders fire in the order 1-8-4-3-6-5-7-2. Timing should be set to 9 degrees before top dead center (BTDC).

Other Specs

  • The correct fuel pump pressure is between 5 and 6.5 lbs. at 1,000 rpm. With air conditioning, this may be 1 to 2 lbs. less. Measure compression pressure at 150 to 170 lbs. for a base engine using the 9.2-to-1 compression ratio. For the HO engine with a 10.5-to-1 compression ratio, measure it at 185 to 210 lbs.
