But somehow Stu misquoted the article above, as it gives the output of 107 CV at 4000rpm as an indication of the power curve. Above (i.e. down page 1) it states about 120cv at 4800 as peak power. I can believe that the .2 difference between the nominal 8:1 and the conservative 7.8:1 at Tobrouk could account for the roughly 5CV difference between the "nominal" 125CV of the 256 engine and the "about 120" of the Tobrouk version. As you are obviusly more prepared than I am on those very engines, I would settle if you disagree... 
On another point, it's strange to me that the 2300MM bears the 915001 VIN, i.e. the #1 of the new series, if it remained a 2.3 during its early racing career. Was the VIN of that car somehow "forged" when converted to 256? Or was it more of a prototype of the new series?
