Seeking reviews on Cummins Signature 600

It seems like those signatures needed an inframe before 600k, while the lower hp ones were making it all the way to 1.5 mil with only main bearings done

 

Rebuild what you've got with either cummins or aftermarket parts for the HP you want. Compound turbo it. Tune it ... live life happy. If you are dead set on a transplant ... put an e model in it ... properly built and tuned yellow motors make life much happier

 

Heard that too. Lugging it too much?

If Rawze is still active on the interweb he's well respected on the ISX and could give you a good idea.

 

I a 2002 Pete with a Sig 600 in it. Closing in on a million miles and have had nothing but good luck with the engine. Just minor work on it like you would expect with water pump and such going out on it.

 

Same truck I have. The previous owner replaced the original at 900K and I bought the truck 50K later. We're up to 1.35million now with no issues at all.

 

I believe you can. It would be labor intensive, as you would need to change all the brackets ect...
