[citation needed]. Stroking the 350 to a larger displacement is not an option, as the camshaft is too close to the cylinders already and there is not enough room. The bore and stroke refer to the width of the cylinder and the distance it travels. The front cam bearing was installed with the oiling hole at 3 oclock. Be careful; make sure you go in straight so you dont go off the edge of the cam bearing. Wheels and Tires: Weld Wheels all around, 5" fronts with 195x75x15" tires.

Originally intended for 180-cubic-inch (2.9L) displacement, Buick was designated by GM as the engine design leader and decided to begin with a larger, 215-cubic-inch (3.5L) size, which was deemed ideal for the new senior compact cars introduced for the 1961 model year. You can open this to inch, but that will require re-tapping the oil pressure sending unit hole, to 3/8 pipe, from factory 1/4 pipe thread. Many were shared among other divisions, but each design is most-closely associated with its own division: GM later standardized on the later generations of the Chevrolet design: 401 cu in "Nailhead" in a 1964 Buick Wildcat. The engine was an overhead valve design (OHV) with two-valves per cylinder, for 16 total, and used hydraulic lifters.

Allowing for better flow reduces exhaust reversion and increases scavenging, which allows for cleaner and cooler air to enter in the combustion chamber. Six displacements of the engine were used in two generations between 1953 and 1966, varying from 264cuin (4.3L) to 425cuin (7.0L); three displacements of standard cast-iron small blocks between 1964 and 1981, and 300cuin (4.9L) and 350cuin (5.7L); one of the 215cuin (3.5L) aluminum blocks (1961-1963); and three big blocks between 1967 and 1976 and 400cuin (6.6L) and 455cuin (7.5L). . This can be done with a standard drill bit. Of all the GM "350s", the Buick has the longest piston stroke. I haven't taken the heads off the RP block but I think the difference between the 74 and 69 motors are the cylinder head volumes are less on the 69 giving it the higher compression. Saves the costly expense of changing to higher compression pistons. The engine transmits power to the wheels compliments of a 3 speed manual gearbox. Of all the GM "350s", the Buick has the longest piston stroke. 3) (model since September 1971 for North America U.S.).
