" The only other way to tell what it actually is now, is to open it and measure the cylinder diameter and multiply that by the stroke " You need more than that to figure total displacement brother. You have to factor in Pi ( 3.14 ) or use a calculator that factors it in automatically. 103' engine ...3.88 * 4.38 = 16.99 * 2 = 33.98 * 3.14 = 106.72 ... At least that's the way I remember doing it.

Just ride it. Open it up when something goes wrong, if it runs strong, run it.
I'd tell everyone it's an 88" just to **** em off.

Who cares what the displacement is, just enjoy those big jugs and ride on

If it already runs strong, don`t mess with it. "If it ain`t broke don`t fix it".

The answer using the corrected formula = 103.52 cu. inches total for 2 cylinders (using the bore and stroke he used).
