If you’re taking an engine apart and are unsure of the cubic inch or the crank stroke, here is a quick way to figure it out. Simply rotate the engine until one piston is at BDC. Take a measurement from the deck of your block down to the deck of the piston. You can use a tape measure or a machinist scale. This will be the stroke of the crankshaft.
