I have a full 3 view of ferraris 049 v10 in dxf, and few others which i've guesstimated.
Generally, the timing gears are a an 8mm tooth pitch, the rods are 102 to 113, the strokes are 39 to 42mm, the bores 95 to 98mm, included valve angles 19 degrees up to 25, big ends 36mm, mains 39mm, inlet valves tend to be dictated by rpm rather than bore space with exhaust valves paying the price on remaining 'real estate' 38 to 42mm.
The valve bowls are nearly non existent, almost a straight path, the valve lifts are mega 16mm upwards, thin rings, 1x 0.8 for compression, 1x 2.5 for oil.
All the internals are forged, xrayed and have perfect meturlligy, no shoestring copies to be had here unless you lower the rpm into a motorcycle type region (20 to 22 mps).
The real beauty is the packaging, Asiatech and Ferrari 056 onwards are my faves, pure art!
