my 68 beetle I have a 87mm pistion kit this is a twin port with a stage two cam from osborne park griders what is the capacity of the motor 1770cc ?
Its not the orig motor the crank is out of a type three 1600 I have not started it should I or will it %^&$ up ! seagull:cry
The formula for working this out is
Bore X Bore X Stroke X 0.0031416 = Capacity
or in your case
87mm X 87mm X 69mm X 0.0031416 = 1640.74
Or as they say 1640cc.
Hope this helps.
