A report by Jo Marchant New Scientist August 31st 2010
Cutting blades that are made of obsidan a volcanic glass that forms a sharp edge when it fractures, was found at the early bronze age settlement called Ikizztepe, in the Black Sea Provence of Samsun in Turkey.
The investigation found 700 skulls in a nearby graveyard and 14 sculls had cuts that could only have been made with a very sharp tool.
The cut marks show the blade was used to make a rectangular opening all the way through the scull.
The patients lived at least 3 years after the surgery because the skull had tried to close the wound.

I hope this interested you to
Ford just refers to it as the 390 but it would be ( around 6.4 liters )
390 squared is 390 times 390 = 152,100
46% of 390= 46% * 390= 0.46 * 390= 179.4
Depends on year and application, but most 390-4s were rated at around 320 gross hp.
390 is divisible by 3: 390/3 = 130 390 is not divisible by 9: 390/9 = 43.3 recurring (that is, 43.3333..) 390 is divisible by 10: 390/10 = 39
20% more of 390= 390 + (0.2 x 390) = 468
In Africa, 30,000 to 35,000. In India, around 390 -410.
390 000!
70% of 390 = 273 = 70% * 390 = 70%/100% * 390 = 273
110 percent of 390 =429 110% of 390 = 110% * 390 = 110%/100% * 390 = 429/1 or 429
390 x 3 = 1170 390 ÷ 3 = 130
Around 380 or 390
