Just measure the stroke by putting something down the spark plug hole. Measure at BDC, then turn the engine over and measure again at TDC.

Or if you're left handed or lazy just measure with number one at TDC and without moving again measure number two which will be at BDC.

Stock is 88mm and the usual "stroker" is 100mm.

since the engine is apart, look at the crank and see if you find any casting numbers
