    I inherited a 345 motor, fresh from the machine shop. sat on the shelf for years.

    Anyone know much about these motors? I do not have a car in mind for it yet, but the price was right. so I grabbed it up.

    They were designed to be a 200,000 mile engine by using heavier duty timing chains, hard valves and seats, etc. Very good engines. If you look for the right parts out of early 70's pickups and travelalls you should be able to pick up a GM turbo 400 trans to fit one, I think they used the same setup as the Jeep Wagoneers.

    I have had several..still have a 67 TravelAll with 345..granny gear 4spd..and 4.11 gears. A great tow vehicle..will tow anything wether or not that thing wants to be towed..!
    Rev's to about 3800-4000 max. An industrial type type motor used in backhoes..graders..everything IH made.
    Very good torque..not a high HP unit..very understressed..extremely long lived.

    They are NOT fuel efficent. My TravelAll sits..4-6MPG towing..a little better naked...maybe 8mpg.

    Here is a article on building a "performance 345"..

    As stated above, they are good engines made to live a long time. I've driven them for close to 20 years now never blew one up.

    The engines weigh almost as much as a big block Chevy. They came with T-18 and T-19 manual transmissions or 727 Torquflite auto transmissions in most applications. There was a 5-speed OD manual in some of the pickup and Travelall applications as well. The 727 has a special case for Internationals but uses the common 727 internals.

    Some aftermarket speed parts are available such as Schneider Cams, headers, and gear reduction starters. Try Super Scout Specialists or Scout MADness as vendors for parts. The Binder Bulletin is a forum for IHC enthusiasts and they know all the details you'll ever want to know about these engines.

    XLR8, actually it has a timing gear set up. No chain to stretch/wad/break!

    That's right, I forgot about the timing gears, I knew there was some heavy duty parts there. I overhauled a couple of these but it was over 20 years ago so it's hard to remember all the details. I did think that some IH's had turbo 400's though, the same universal mount 400 that was used by Jeep, I could be wrong on that too though.

    When timing, time off of the #8 cylinder.

    The Torqueflite is a normal Chrysler unit, there's an adapter plate to make it fit the Binder pattern. The 345 is pretty much an orphan, IHC doesn't service them any more. They're too big and heavy for a car, anyway. Sell it to a farmer!
     
  10. Sadly, you are wrong, else I would NOT have been out so much money when I had to replace a Scout's 727 case, which IS IH specific.

    My 1972 jeep cj5 had the 304 v8. And my friend with same jeep replaced his 304 with a 345.
    Was a direct bolt in swap iirc. There were several amc with the 304. My motor was replaced with a 304 from a matador. Just a idea to look at, for possible cars and trans.
    That 345 in a cj5 was a torque monster.

    Used in Caterpillar 30,000# capacity fork trucks too. Ran well and dependable. I imagine mileage would be dependent like any other engine - dependent on gear ratios and tire sizes used. Not too many back when this was new had overdrives and freeway traveling in mind.

  15. I worked on the Scout line (IH) back in the day, ran a lot of 345's, I bought 2 new Scouts with the 345's, good engine!

    Heavy, slow, thirsty, expensive; other than those shortcomings, every rod should run a Binder V8.

    We Packard V8 guys need some underdog to dis, cause we're heavy and expensive.

  17. My 70 dump truck has a 345. Ive got a Pk with a 304. and a binder 304 and 345 are the same design. Ive even got two of the slant 4 cyls. AMC 304s are not the same engine. and the international V8 are all blueprinted .the pistons all have the same deck height and the combustion chambers all have the same CC,s. You cant replace just one head. They have to be matched sets. Not really a hot rod engine. Sell it on craigslist under farm and garden. Some farmer needs it. sell it and get a old hemi or a nailhead.
     
  18. Never came backed by a th400. And not in any way related to amc. 304 amc is not the same as 304 IH. IH trucks came with 401 amc for a short while when there was a shortage of sv's
    They had borgwarner autos and 727s but the case was IH only. Not interchangeable with chrysler.
    If your going for Big power you will be disappointed.
    You need to be on the binder planet forum for all IH info.
    I daily drive a 71 with a 392/BW11
    If you want to do anything with it contact Brendan at BarnesIH. He has the largest collection of trucks and Nos parts on the east coast.

    They run forever, drink lots of gas, don't make enough power to break anything. An industrial engine from days gone by....
