Repowering a Peterbuilt

[Unilevers]

i got nothing bad to say about a DDEC 5 s60 tuned properly and i have done quite a few swaps over the years with them into petes. It works out well and isnt very hard to do but you will need some parts.

The ddec 5 will never touch your 871 properly tuned and built though. Those upper tier hand built motors do 7.5mpg+ for a million miles easily - its just hard finding someone willing to take the time and is able to build you one.
