hotrods with International V8s?

boy that was a good video, anyone remember what came in the travel alls? boy those things were tough, we had one for years in ohio, before the rust finally got it. tank rusted out, so my dad put another one in the back.

 

I have heard from several people that worked for IH that the 392 and 345 V8 were tested at WOT for 1,000 hours for durability testing.

I have one in a '80 Scout II that will not die, durable yes, fast NO.

 

My '69 wrecker has a 345, Those engines are dam near industructable! When I baught it 10 years back, Drove it 500 miles home with a Firebird on the deck. ( this truck was mechanicly neglected) It got 10 mpg. Giving it a complete tune-up when home I noticed it had three diffrent size and brands sparkplugs! Ive seen those Travell Alls with anything from a straight six to a 392. I would like to see an International powerplant in an old kb.

 

I used to mud race a Scout II, first with a 345 and later with a 392. I had major port work done to the 345 heads, and used them on the 392. 345 had much smaller chambers than the 392 heads. Near 12.1 compression ratio and would rev to 5500 before it quit making power. Internally these motors are way overbuilt (heavy). I beat up on everyone for 3 years with it. Was a blast.

 

Are the bottom ends the same (bore) 304-345-392?

 

I worked at a school bus garage in from about 1977-81.About 100 busses,half IHC with 345's and a few 392's.The others were Fords with 361's.The IHC engines did last somewhat longer than FE Fords.The FE's only real problem was suckin in intake gaskets on some engines,heavy fuckin manifold.Some IHC 345's made in the late 70's has head gasket issues,leaked coolant ,and ruined a piston.Power wise? Both stick and 4 speed Allison automatics,I felt the Fords pulled a little better.But the IHC may have run a bit smoother.We're talkin school busses that weigh about 16,000-18,000 pounds empty.

 

not original frame, but you can see how tight it is. inner fenders?...not likely.

 

Well, as I age, my memory seems to fade in and out. Not sure if it's really age related, because I'm really not that old. Probably more likely I just have too many irons in the fire. Hope I didn't offend you here with this misinformation.

If come across my phone number sheet (I had put together a list of numbers for everything about 8 years ago) I'll be able to tell you for sure. I had wrote down the particulars from our conversation. For sure it was over 700hp, mileage for some reason I'm thinking 15, maybe because my 2004 Ram SRT-10 got 14 and my memory is playing tricks on me. I don't know for sure, but when I come across it and if I remember I'll post it here on this thread. I have the issue of 4Wheeler that his Scout was in too, it might also be in there. Could even be that what he had quoted in 4 wheeler and what he told me were 2 different things and that could be screwing me up. Either way, I'll check it out one day. Regardless, the thing made a shit load of power and had (in my recollection) impressive mileage for a lifted 30 year old truck.

My tow vehicle I bought in 1972..a 67 Travellall 1200 3/4ton..with extra heavy springs/shocks..392..4bbl. 4:10 gears..4spd..1st a crawler "granny" gear. NO power steering ( I must have been real strong back then) 31x10.5 tires !

Top speed was about 55mph or so..gas mileage was about 6mpg towing..maybe as high as 8mpg naked. These are not high rev motors..If I remember under 4000 rev limit.
I still have it..but it has sat for years now. No rust..even paint looks OK..

Used it as a tractor on my property..it'll tow anything whether it wants to be towed or not...
Nothing seemed too heavy..too strong..or too big for that Travellall..
Had several others..wife had a plush 390..72 in heavy GREEN METALIC..almost a FLAKE..! She loved her custom Travelall back in the early 80s..

Drove to Mazatlan..several times with the big truck. Hauled a XK150 on a trailer over Wolf Creek Pass in snow..trailered a 35 Ford accross Texas in august. Hauled several racers to different tracks.
Used to get my 327 CJ out of wedges..or other stupid shit..big chain..drag anything.

Can't kill it..

Just can't do the gas mileage anymore..and those saddle tanks always leaked.

Should sell it..won't ever scrap it...

 

That's cool...no big deal...I just remebered seeing the 700hp thing somewhere before and did a search. I'd really like to see the 4Wheeler article, too. This year at the IH Scout Nationals in Springfield, OH, I talked to the guy that owns this engine:
http://www.youtube.com/watch?v=IqdYVwVrX1E
This highly modified 345 is putting down 432hp/501tq at the flywheel. It also weren't even remotely close to cheap to build. I just gotta wonder what was done in addition to gain the extra 270hp in this 392 you're talking about. This guy is running 33's I think...maaaaaybe 35's, but I don't know what his mileage is. I told him I got 17-18 with my LT1'd Scout on 31's, and he acted like his didn't do that well.

 

Here's another good example of a decent performing IH engine:

There was a another guy on the binderbulletin names DaveSr who had a pulling truck. His 392 was pushing over 500hp naturally aspirated, he had a custom valve train setup using Harland Sharp roller rockers and extensive head work. He ended up jumping up to a more competitive class and had to build an aftermarket BBC. He said later on the website that he could build 3 400hp IH engines for the price of one SBC, or something to that effect.

I guess at the end of the day I look at it this way, could I build a SBC or equivalent with more power for the same money? Probably. But it wouldn't be as cool to me. Kind of like guys that spend lots of coin building radical flatheads. Either way, it's just for fun.

I'm helping a buddy build his 30s IH pickup hot-rod - power plant will be an IH 304 at 344 cid, with a 6-71 blower on top - with the hood and hood sides removed.

We're looking into a crank-fire distributorless ignition for it now so the blower won't have to sit ridiculously high to clear the distributor.

They need a ton of head work - and even then, they don't flow well.

Realizing that there are 4 different castings of blocks, the basic progression was the 266 was bored out to make the 304, which was stroked to make the 345, which was bored to make the 392.

You can use 304 pistons in a 345. You can use a 266 crank in a 304, or a 345 crank in a 392 but you must rebalance everything (strokes are the same).

For many years, 345/392 shared con-rods.

They all use the same main and rod bearings.

I have a few hopped up IH power plants around, but nothing in a "hot rod" - there's a built 392 in my 74 1T 4dr IH tow rig, a built 304 in my short-course race Scout, and a built 392 going into short-course race Scout #2.

 

I remember many moons ago at Lion's Drag Strip there must have been a "Odd Ball" get together and I know I saw dragsters running big ol stright 8 Buicks, flathead Olds/Pontiac stright 8s and a load of other stuff. I'd bet you would have seen a binder or two plus other odd ball power plants.
Does anybody remember anything like that?

 

I will be building a 36 international with a latham blown 392 soon as i get my shop built.

 

Yes, but the bellhousing bolt pattern is different. The guts will swap out, and any mod you can do to a Chrysler TorqueFlite, you can do to the IH unit.

 

I am in the process of building a 1941 K-2 with a 1980 Scout 345 4-barrel, NV4500 5-speed, and a scout 2 dana 44 rear. Its on a cut down 1985 S-10 chassis, had to section the front crossmember about 1 1/2"s to get the engine where i wanted it and move the firewall back 3"s to get the weight off the front axle some. Also building a 1936 C-1 with a 392 (still in the parts collecting stage, been in that stage for around 6 years now).

 

We are an ihc family. Had a Dealership.

That 354 in that that old tandem grain truck was simply a torque monster.

 

That is nearly true, when IHC quoted a redline for an engine. They were quoting the maximum operating speed rather than the point where the engine may suffer internal damage. For example, I had an 152 ci I4 that had a 4000 rpm redline. You could run it at 4000 rpm forever without hurting it one bit.

 

In high school my friend Jason had a 78 scout II we used to pull my car to the track with. It was a 392 with 345 heads, a 4bbl intake manifold with an 1850 Holley, and a 268 comp cam. When we pulled my 56 Chevy to the track, you didn't even know it was back there. It would smoke all 4 - had 30x9.5's on it. Don't have power numbers.

 

Here is a video of a blown 345 you Binder fans might get a kick out of.
