    07 T600 Kenworth 475 Acert with fresh overhaul 13speed 3:55 rears 610,000 on Truck $60k
    2010 386 Peterbilt 585 ISX TURNED up to 635hp overhauled 140,000 with full delete 13 Speed 3:55 rears 718,000 on Truck $48k

    Ive never really had good luck with twin turbo acerts, mileage was low pulling a bull rack. I realize your fuel mileage is never good with a Bullrack.

    I’ll be pulling a High side hopper nation wide.
    Curious what others thoughts are on motors I personally like the 386 over T600 but want to see what others think on fuel mileage, C-15 vs ISX

    if you prefer a 386, I'm pretty sure you can find a 2007 one with a c15. I'm not a fan of acerts either but I would own a c15 (non SDP lol) before a isx. If you get someone to work some magic on the ECM the twin turbo can be a powerhouse getting good fuel mileage. Steven Bradford does some crazy work.

    Both trucks are priced high. If I had to choose it would be the isx, If it was a cm871 and I verified what all was actually done on the rebuild
