4.040". The standard bore is 4.00".
Each cylinder has been re-bored to a diameter .030" larger than it came from the factory. .030 oversize isn't much. It's done to correct slight cylinder tapering and to put the engine back into condition that it will last. It really isn't enough size difference to produce noticably more horsepower. Note that when the cylinder is bored .030 over, you'll also need pistons and rings that are manufactured to that size.
A 350 starts out with a 4.000" bore and a 3.48" crankshaft stroke which really only gives you 349.8 cubic inches. (Chevy rounded it up to 350) Your engine which has the same stroke of 3.48 but now is bored .030" over (making the cylinder bored size now 4.030) total size of 355.1 cubic inches or just a 355.
A 3 cylinder engine : Compact in size, cheaper to built, light in weight, Less fuel consumption. 4 cylinder engine: bigger in size, smoother sounding than 3 Cylinder engine.
It means that the cylinder has been bored over what its original size was and now has a larger piston than what it was originally manufactured with. It means a slightly larger displacement than before and most times gives more power.
I just got my cylinder back from millennium technologies they bored the cylinder to the stock piston size that was 1.888 and honed the cylinder to 1.890.
A 4.8Liter engine is an 8 cylinder engine...
a Chevy 350 bored .060 over would be 360.4 cubic inches
multiple cylinders create better torque, efficiency, and are better balanced. In addition, the same identical size engines would have large differences in piston size/weight, rod size/weight, bearing stress, etc.
Depends on if (and how may tmes) the cylinder has been bored.
One would use over-sized pistons and rings (TOGETHER!) when the cylinder has been bored to accept the next size piston. For instance, damage to a cylinder wall may necessitate boring the cylinder an extra 0.020" (twenty-thousandths of an inch). You would then use a piston and ring set that was 0.020" larger than the originals.
the engine can be either a: 1.6 liter 4 cylinder or 1.8 liter 4 cylinder
If this is in a Ford Ranger : ( 1989 to 1997 is a 2.3 liter four cylinder engine ) ( 1998 to 2001 is a 2.5 liter four cylinder engine )
