When I said it is the same size as stock it refer to crown of the piston being in the same distance from the center of the crankshaft as a stock engine.The added stroke 76.8 vs 69 which would move the piston crown height out 7.8 mm is canceled out by using "B" stroker pistons which have a shorter wrist pin to PCH ( piston crown height).The need for barrel spacer and longer pushrods and all other B.S. that go's into build a stroker is gone. This is the e-z way to go. Want to see a problem you run into with a long stroke goto
