Or you can look at this chart. http://images12.fotki.com/v335/photos/9/1648479/9195830/engine_disp_chart-vi.jpg . On 11/30/2011 11:34 PM, Gerald Livingston wrote:
THERE it is!! I just knew building an engine required fresh PI(E). But your equation gives him a 1907353.88895744cc engine. It's actually: ((bore/10) x (bore/10) x (stroke/10) x (3.14159265 / 4) x cylinders)) /10 puts BORE and STROKE in cm, not mm OR, since we have a 4 cylinder engine we can use: (bore x bore x stroke x 3.14159265)/1000 rather than dividing the bore and stroke by 10 abd pi by 4 and then multiplying the result of that by 4 again so, 8.8 x 8.8 x 7.84 x .785398162 x 4 = 1907.353887743 cc OR 88 x 88 x 78.4 x 3.14159265 / 1000 = 1907.353888957 cc for 88mm pistons and a 78.4mm stroke G2 On Wed, 30 Nov 2011 22:26:41 -0600 Lisa and the Stevester<stevescott@xxxxxxxxx> wrote:Did anyone answer the question?

When I had it built 9 or 10 years ago I was told it was a 1914. It is 74.8 x 88. If I just multiply that I get 6582.4 which would mean I have a 6 ½ liter engine and I am pretty sure that is wrong. How do I get to 1914?
