Let's say your Buying a set of pistons to retain stock stroke and bore. You come across a set with stock bore but a 4 inch stroke instead of the stock 3.662 stroke. Can you use these stroked pistons on the stock bore and stock stroke. Is the only difference from those pistons that one has a shorter skirt from the other.

Usually a stroker piston will have the pin moved up closer to the crown to compensate for the increased stroke and will not work on a stock stroke. Pistons are designed to sit flush(relatively) with the deck surface using a specific stroke and connecting rod length.

Well... You could use those pistons but it would require longer custom length rods, so probably not worth the savings of scoring some inexpensive pistons vs buying the correct pin height pistons for your rod/crank combo.

you can use this formula to calculate needed rod length

deck height - piston pin height - 1/2 stroke = needed rod length

Not to be ****, and you probably made a typo, but stock stroke is 3.622 (think 3-5/8"), NOT 3.662.

If you used stroker pistons with a stock stroke and rod length, you would add deck clearance (the pistons would miss coming to the deck) by ½ the extra stroke.

Obviously hard to get a good compression ratio under such circumstances.

Not to be REALLY ****, but you replied to a 9 year old thread...
