Calculate Deck Height, Rod Length, Piston Pin Height, Finished Block Height, or Stroke

  Fill in any four of the five values to calculate the fifth.

Stroke - The stroke of the crankshaft in inches. Distance piston moves from TDC to BDC
Rod Length - The rod length center to center of pin hole and big end in inches.
Piston Pin Height - Also called compression height; center of pin hole to top of flat part of piston.
Finished Block Height - Height from centerline of crank mains to top of block deck.
Deck Height - Distance from top of piston flat to the deck surface - Negative number for piston above deck
