12.7 vs 14l

14L with egr delete. Mad power house and fuel efficient.

 

I run a 1999 Pete 379EXHD Ultracab w/ the BIG 70 inch Ultra sleeper. Sits on 270 wb. Powered by 12.7 Detroit. Its the rare straight 500hp/1850 torque engine. Backed by a 13 speed w/3.55 gearing. I get 7-7.5 mpg loaded ALL DAY LONG. Empty is 8-9 & bobtail is 11-12. When u have a big hood out in front of you, having a smaller engine that gets stupid good fuel economy is the biggest cool factor in my book...

 

We used to have an '00 14.0 L Series 60. It had over a million miles when we bought it. It pulled good. Burned through oil pretty good too.

 

dont be scared of the egr 14 liter theres ppl out there that can make them run but if you can get a pre egr id go for that in a min

 

We've put together quite a few build packages for Glider Kits with the factory reman 14.0L Detroit Pre-EGR motor, a much better comparison to a 6NZ than the 12.7L. Fuel economy is still better than the CAT but more power than the 12.7, great motor!

 

I remember when dad used to have a 2000 century with 12.7 detroit. Now it's gone. 1999-2006 RIP.
