The guy wants $ 8,500.00 for the 400hp ISL, and an Allison automatic. App. mileage is 1500. He also has a detroit 11.1 series with 115k miles. He wants $ 4,500.00 for the engine.

Eric, I looked at an ISL with Allison also. I think the guy had it for 4.5K with rear end and all from a RV. I looked it up to see what MPG they were getting. Most said 6.5 to 7. Not that impressive, may be to small? Working hard all the time. Just a thought.  Tom Y

That's a good price, considering the Allison automatic is worth $10,000 alone.  Make sure it comes with all wiring, computers, accelerator and shifter.  Good Luck, TomC

I offer this: I have an 01 Eagle with a 60 series and HT741, 3:36 gear. Runs great. I get about 7 MPG towing a car in all conditions.
I also have a Revolution 42 LE(09) with a 400 HP ISL. It runs great and gets about 7MPG towing also! Yes the eagle has more torque and accelerates faster but not a big difference. Hills are not a big issue either. Just finished a 4000 mile trip to west coast and back with the S&S and had no power issues.
Take it for what its worth. I think the ISL deal is SMOKING  - grab it before it is gone.

TomC, no way is the 3000MH transmission worth 10 grand and that is the model S&S uses behind the ISL 400 along with 4:63 rear gears a luxury he doesn't have with his Eagle and the drop box. 
 Eric would never be able to use 6th gear to get fuel mileage from that engine the 4:10 ratio if you can locate one and those are few and far between is the lowest he can go

I called Allison tech today with a few questions. He said the 3000mh is programable with one or two overdrives. That dosen't sound like a big issue. I also read somewhere that the world transmission can only be programed to work with a ddec III and up. That would eliminate the 11.1 detroit. He has three 60's 12.7l in wrecked trucks. He said he probably had one or two with less than 300k that he would have in the 3-4 thousand range. I don't know which version they are.  He also has several 4000 allisons which is the corredt one for the 60. It is a lot longer than the 3000. I looked at the size and wgt. The ISL is much smaller and over 1000lbs  lighter. I may jusy have to gussy up and go to camping world, and act very interested in a 40' coach with a 400 ISL. A good test drive will tell a lot. There is a 6% 4.5 mile grade less than 10 miles from them!!

If Eric is using the typical 11R-24.5 that other Eagles are running, and with his 4.10 ratio, his speed and rpm would be- 1951rpm @ 60mph, 2114rpm @ 65mph in 4th gear, 1585rpm @ 65mph, 1705rpm @ 70mph, 1829rpm @ 75mph in 5th gear. And yes, 6th would not be attainable with the 4.1 gears.  Remember though-both the World Transmission and the HT740 have just about the same gear ratios from 1st through 4th.  Good Luck, TomC

P.S: DO NOT involve yourself with any Caterpillar truck/bus products.  All of the factory sales reps for these products have been released from their jobs, and Caterpillar factory backing on their engines have just about gone to zero!

And when was the last time we had "factory backing" on our beloved 2 strokes?
Just because it's not a good idea for the everyday trucker who makes his living using these engines to use them, doesn't mean that there is no use for them in our "hobby". (that's what it is for most here isn't it?)

And yer right I wouldn't be having one in my "fleet" either, but my fleet is different than a private coach too!

BK, Cashmans in Vegas is still doing a booming business for truckers and buses with Cat engines guess someone forgot to tell her, I sure hope TomC informs us when he replaces his 3406 Cat with a ISL

Clifford that's my point! CAT still has tons of support compared to 2 strokes, but if you listen to TomC they are dinosaurs!

not meaning to bash Tom after all if I sold NEW trucks for a living, I'd probably be the same way!

I haven't looked at the cat yet. I have a 242 cat skidsteer and have been less than impressed since new. It does have a perkins though. I just know this is a job I want to do once only!!! The old 8-71 is running fine as long as you don't let granny slow you down on a hill!! I have a 3:73 rear in my bus. I am doing app. 71-72 mph at 2100 rpm. I will need an overdrive tranny to run a four stroke at the proper rum for the best mileage.

There are a TON of companies making after market parts for 2 stroke engines, and MTU are still making certain 2 stroke engines for military use.  You can still order electronics from Detroit and other companies
Cat on the other hand is the sole provider of electronics for their engines.  I liked their engines up till 2007 where they tightened their own noose by using a different smog system then everyone else (sort of what we're seeing now with International engines based on MAN engines).  If you can find any Cat engine older then 2007, then yes, I'd use it myself.  But they're ACERT system was a dismal failure with many law suites pending against the company.  Personally, would stay away from the 3126 or C7 because of the hydraulic injection system.  C9's-there weren't very many made, but were good engines.  3176 stay away from with its' aluminum block/head spacer plate.  C10, C12 great engines for buses!  C11, C13 with twin turbos, stay away from.  3406B, C, E great engines. C15 with single turbo-great engine.  Once again, stay away from the twin turbo'd C15.  C16-a beast!  
After running a 8V-92TA, 6V-92TA, and now my 8V-71TATAIC on my bus, I can say without a shadow of a doubt that my Caterpillar 3406B mechanically injected jacket water aftercooled 400hp engine in my truck is the most reliable, low maintenance engine I've ever had-I drove it almost 700,000 miles.  And it was a big determining factor why I'm converting my truck now.  Since it has less than 200,000 miles on the last in frame and runs like a clock.  Good Luck, TomC
