He said, "875 Newton Meters at the wheels."
That's only 645 ft lbs of torque.

He also said it has a forged crankshaft and a 2-piece block ; sounds like a girdle, but I don't know everything.
They seem to talk about a 6.5 that's different from ours, on their website;
"6.5L CHEV DIESEL
Originally designed as a ‘workhorse’ engine by GM division Detroit Diesel, this light truck engine was fitted to Chevrolet & GMC pick-up trucks and SUV’s including the Suburban from 1982 until 2000, at which time this engine was replaced by the 6.6 litre Duramax range. "
OUR 6.5s were originally designed to be cheap to build and economical on fuel, as I have read.
They also say,
"The 6.5 has a lot going for it. It is available with electronic or mechanical fuel injection. There is a 12-volt wire to the fuel shut-off solenoid, and another to the oil pressure gauge, so wiring on the very popular mechanical pump is easy.
This together with sealed hydraulic roller cam followers, a double roller timing chain and mechanical indirect fuel injection make the 6.5 a reliable, low maintenance proposition. For these reasons, this engine is the natural choice for rural Australia, for simplicity, robustness and longevity.
You can expect 500,000 kilometres from a new 6.5."
no news there...
