Are you guys serious ??
Tha thing is EASY !!
All you have to do:
1. save the picture in ur computer.
2. grab a water container and measure any part, so that u can figure out the "scale" of the picture.
3. import raster image to CAD
4. assuming u have the scale properly set, measure the vertical displacement of the piston and the approx. diameter.
number I scientifically measured:
stroke: 6.540 cm
diameter: 9.0 cm
6. Calculate the volume per cylinder. (for those not good at math: area of base x height
)
each cylinder: 415.8459
7. multiply by 6 (he told us it was a V6)
Total: 2.498cc
8. cash in the $1 !!
It is a V6 Alfa Romeo Twin Spark. The displacement MATCHES perfectly and u can also see it has twin sparks. Just look at the two signs where the sparks were. (you may have to use photoshop to regenerate the image at super zoom mode)
NO WAY!
