    I added a new tool to the toolbox: The Engine Displacement Calculator determines the displacement of an engine by two methods; selecting the engine to get the geometry of the configuration, or by the geometry to get the engine. You may select the engine manufacturer and designation to get the exact parameters. You may then play with the various components until you get the information you desire or you may just fill in the various fields to get the size you desire. Entry for bore and stroke is in inches. Displacement is given in cubic inches, liters and CCs.

    Try the Engine Displacement Calculator

    Hey now... no claims were made -- you have to start somewhere with these kind of tools. I build and provide alot of online data tools, and none of them have been perfect out of the shoot.

    I'll be happy to put you on the payroll here BackYard, if you think you can help me out here with some programming expertise...

    Thanks! I've bookmarked it...
     
  6. the .030 over 283 in my `36 ford is exactly 287.437 cubic inches

    thanks for posting

    bore x stroke x 3.1416 x no of cylinders = cubic inches

    or this works... Bore X Bore X Stroke X .7854 X # of cyl = CI for any make!!
     
  10. I came here to say that. Learned that when I was 14 in shop.

    3.1416 = Pi for those of you with one of them there fancy calculators.

    All of you are correct. It is not rocket science to convert to cubic inches. It is shop class 101.

    Now, go google to find the conversion to Liters, Milliliters and CCs. Now run and find your calculator. Make sure you can find it and hope the batteries are still good. Now, go research 419 foreign and domestic engines and their specs and run all of your calculations. Now create a web site that lets the access your work anytime they need it.

    Or don't. Because someone has made a simple tool for you to use whenever you need it for free.

    More importantly, this tool allows you to "play" with the various components until you get the information you desire - increase bore size for example...

    Enjoy - should you choose not to hunt for your calculator ;)

  12. I wasn't trying to be snarky. I appreciate the effort of the site. I was just throwing out what was drilled in my head by a great teacher.

    Another good rule of thumb is that 1 Liter = 60 Cubic inches (rounded).

    3.8 Liters = 1 gallon for you GM guys (or those of you with an American Standard toilet)

    "All of you are correct. It is not rocket science to convert to cubic inches. It is shop class 101."

    Not exactly.

    This one is: Bore X Bore X Stroke X .7854 X # of cyl = CI

    This one is no good:

    bore x stroke x 3.1416 x no of cylinders = cubic inches

    By the way, if you want an approximation for metric measure,

    Cubic inches / 61 is approximately the number of liters.

    Multiply the above by 1000 to get cc.

    Sorry to bore the multitudes, but some of us are just math geeks......

    But maybe I don't type fast enough.......
