Cummins NTC 290 inframe build

Will I have to change the shim of the cam followers, for the 160 CPL? Do I need to remove a cam follower to see what gaskets are there now?

 

Well, I’ve been in touch with Pittsburgh Power and told them my CPL and that I’m wanting the engine hotter but I don’t want to change the timing. The Cummins guru(big and small cam guy) there says, lower compression pistons, different injectors and turbo. He called this build in a small cam a, “ 350 Magnum”. Said he’s seen plenty of these builds go to 425hp safely. Waiting for a price quote.

 

Well I ain’t bought nothing yet and more than likely they’ll be to expensive. I initially called them to ask what CPL would interchange, without changing the timing(same as 0217). His answer was, “well I can’t sell parts if I give all the answers over the phone.” I’m not necessarily going that route but I am investigating.

 

CPL 0248 was suggested to me and that there was no need for a step key. It used 215420 pistons, along with pump and injectors for 0248. Swap the turbos and add AC if desired. This was a topic on the 0217 CPL from an ATHS forum.

When looking through the CPL book, the only difference I see between 0160 and 0248, is the injectors. On the other hand, 0248 also says, “this CPL was never made”.
