The Bore of a 350 cid engine is 4.00, the stroke is 3.48 inch..
bore is the diameter of the piston and stroke is the length the piston moves in the cylinder.for example if bore x stroke is 1x3 then 1 is the diameter of the piston and 3 is the length of the cylinder.if bore is greater than stroke then it is a short stroke engine.
That'd be a motor with a 90.5 mm stroke and 69 mm bore.
It refers to the throws of the crankshaft/distance the piston moves. It usually is compared to the bore of the engine. An example a 302 4"bore x 3"stroke is a short stroke motor, by comparison a 5.4L ford v8 3.552" bore x 4.165" stroke.
Enlarging the cylinder bore will increase cc's in a 2 stroke and ci's ina 4 stroke.....

Bore = the (internal) diameter of the cylnder hole in the engine block. Stroke = the distance the piston travels up (or down) the bore during its' cycle. If you multiply the bore dimension by the stroke dimension you will get the volumetric displacement of that cylinder. thus, Vd = (3.1416/4) (dia.) squared x Stroke
The bore and stroke.
