Not sure what equipment but I took it two different shops with the same results

I know I'm allowed 18% but I'm blowing 19% and I've never seen my cat cat blow more than 8%. Which is why I was thinking of changing out the engine. But it sounds like it wouldn't work anyway so I'm not really sure where to go there aren't any other Mack dealers near me and this is dump truck so I don't leave the state ever and none of the shops I've been to are willing to even touch it

Yes I use the truck every day it runs just fine I'm located in Salt Lake City Utah and according to the shops in the area a lot of the Mack trucks are having issues passing the new emission standards. My biggest issue with the truck is it claims to 460hp but compared to my 02 378 Pete with a 475hp cat, the Mack is kind of a gutless wonder. I've considered possibly a bigger turbo to get some more air and hopefully that would give me a little wider power band as well just not sure that's why I decided to post here and pick you guys brains

I'm having problems with my 2005 cv713 Granite passing emissions. Mack wants $20,000 to get it to pass. So I'm wanting to change out the mack engine with a c-15 cat. My question list is quite long so I guess we'll start with the basics. Will it fit under the hood? Is the radiator big enough to keep it cool? Is there an easy way to hook up the ECM or will it need rewired? I suppose those are my biggest worries that I can think of now any help I can get will be greatly appreciated Thank You
