3406 5ek

Might be, might not be. I wouldn't let the engine be the sole decider on trading the truck or not.

 

Why would you want to trade ? Mileage, Year, or because it has 2 turbos ? I wouldn’t do it. I had a 94 5EK series with a good tune, and got 7 mpg all day long.

 

Maybe 290000 since engine rebuild, but a 2007 probably has a million and a half. 2007 is mnx I think, that's the last year cat made a decent engine. I'd look the truck over really good before making a trade. Both are good engines. The engine you have now is a lot less complicated, the acert has more stuff to go wrong.

 

I wouldn't do it simply because the 5EK is ELD exempt.

 

IMO, I'd stick with the 5EK. CAT's 60 Series.

Besides expensive parts, if built right and not tuned ridiculously, they are simple, effective, long lasting.

Wet kits aren't that expensive, twin turbo's are

 

What’s in your 5Ek now, 435, 500, 550 ?

 

I’m curious why you haven’t put your current truck to work. Are just waiting on authority?
With a 1995, are certain you will be able ‘to sign
on’ with somebody? Some outfits have a ‘maximum age’ for owner operators they work with.
