C-12 swap for DD 60 Series

What company did you call to order the DD60 new engine? Are they offering you a warranty?

 

Driven and owned few of both engines and both are amazing. The c12s are decent on fuel and parts are not that bad compared to the big blocks. I'd stick with the cat and maybe upgrade to a 13 speed down the line.

 

I know this is an old post but you can get motorized ball valves and control those with a switch from inside the cab.
