==Stroking a 186:==

===Description:===If the Main Bearing journals are turned down, a 202 Crankshaft will fit into a 186 Engine. 202 Pistons must be used to place the Gudgeon Pin lower down. Using 186 Pistons will result in the Pistons extending up above the deck height by about 1/8". Said another way, 186 Pistons will collide with the Head.
