The compression ratio on the GS350 from 1968-1970 was 9.0:1 for the double-barrel and 10.25:1 for the quadrajet. The bore and stroke was 3.8 and 3.85 inches. The gears must be packed in assembly lube or the pump will never prime. . There is some confusion as well when the number of bolts were reduced in the smaller engine sizes. This will prevent attainment of the proper torque and will require replacement of the damaged part. The high torque nature of the engine was developed to provide adequate acceleration when mated to the Dynaflow transmission which favored smoothness above most other design and marketing objectives. For 1965, the 300 switched to cast-iron heads, raising dry weight to 467lb (212kg), still quite light for a V8 engine of its era. Using an oil pump thrust plate helps increase oil pressure, by eliminating cavities in the oil filter housing, as well as giving a new surface for the gears to run on, in the event the oil filter housing is worn from them riding against it, which is a very common problem. Super power and torque up to 5300 RPM.
