You have to keep in mind that the D12 was designed around European trucking. European trucks are goverened anywhere between 80-90 km/h. And with fuel easily costing $5-6/gallon, fuel economy is going to be very important so the engines are going to be geared towards efficiency.

Can anybody tell me if this engine is any good with a 3.55 rear axle ratio? 3.55 seems geared pretty low without an overdrive so maybe thats why its selling so cheap.

that is way too high a price for that year & mileage. hillcrest motors in s.c. has 05' century's in great shape in & out with 477,000 miles for 19,000. in truck paper.

here is what I think is a better deal. just one of many

2000 FREIGHTLINER FLD13264T-CLASSIC XL Conventional Truck w/ Sleeper For Sale At TruckPaper.com

The ad says this 2000 Freightliner has 414,239 miles. Either the mileage number is missing a "1" in the front or someone is lying. My 2004 International has 425,000 miles and I bought it in 2007 with very low mileage of 165,000 miles. No way a 11-year old truck can have so few miles on the odometer.

you may be right on the true mileage of truck I listed, but that price on the volvo is still too high.

That's because the original post is 3 years old.

I never looked at the date. thought it was a new post.

I am about to trade my '01 Volvo 660 w/ 465 HP Volvo D12 engine that has 1,066,000 miles for an '06 Volvo 780 w/ 465 HP Volvo D12 engine that has 510,000 miles, and I can report that the VED 12 engine is great!

They get great fuel economy, and are highly reliable & long lasting (when you use synthetic oil, in my case). Engine has never been rebuilt, and uses little oil still.
