My dilemma Cat vs Cummins

[Unilevers]

making that SDP Be decent and run properly is gonna cost you 50 grand or more. even then its only ever going to get 6mpg on good days. If you went cat convert it to a 70 pin as SDP parts are crazy expensive and not worth it and dont laugh. im serious atleast 50 grand to make the SDP be reliable and right. A set of ball bearing twins is over 15000 right now for a SDP.

You could get a 871 core, Freshen it and shove it in there for less than that. It will go right in that pete with minimal parts as that truck could come with that engine. go to a wrecker and get the mounts and such. Cut the end off the truck harness and wire on 871 plugs. do some programming and put it on the road. You will be 30ish grand like that and can fix the dam thing and it will get 7.5mpg on a good day. Plus you know how to fix it.

theres a reason theres 6 sdp cores on the ground at my local place......
