Glad I saved that other rebuilt moter I have becuase my new 345 just blew up again its making oil an knockong bad. We dont lknow what the cause is yet but we are in tear down mode right now so soon as I find out il let yall know. Shoulda gone with a Chevy or a commins straight six. Tho the old intertrational 345s have big connecting rods an stuf so hopefully its not a bad bad fix if so ive got anothere hunk of junk rebuilt in the back

I the other rebuilt moter has sat for ever so I needs to be torn down so instead im just going to pull the guts out of the newst moter an put them in the other block or vice versa just combine bother moters an make one good one an get me bac on the road then get rid of it like a bad itch im done with 345s I could get a lighter smaller or bigger moter with more power better gas milage im thinking commings straight six desiel yeah no timing no carb no computer just good power great gas milage awsome off road

I wouldn't give up on the ihc sv's just yet.

Even at the cost of rebuilding an sv it won't come close to the cost of installing diesel power.
 
These engins have a major draw back. They have major thin castings. Especialy between the cylinder hole and the water jacket. Thats why my block cracked so easy. I did my research an IH has been making thin castings between those two things for a while. Im afraid ive got my mind set on deciel they might not be cheap but you have everything to gain
 
If I had your money kid, I'd burn mine.
Who told you IH blocks are thin? Nothing that heavy can be considered "thin." besides, any block can rust from the inside out. That's not an IH problem.
And not to sound like a jerk, but....
After reading every thread you've ever started, I'll remind you that spelling and grammar are basic job skills. There's no harm in composing a proper sentence.
Good luck with the cummins. You'll learn all about thick and heavy with one of those!

What research? Where?
 
A 4bt 3.9l weighs 705 lbs bare. Add 60 lbs for a flywheel, 25 (at least for an adapter for the back of the block for a bellhousing to attach to, then the weight of the front motor dress. At least 850 lbs fitted out. Add at least another 200 for a 6bt 5.9l.

Never mind the clatter from that diesel engine. Modern trucks have a brick-load of soundproofing on the firewall to quiet them.

I drove a few trucks converted to 4bt and although they were peppy enough, the noise would drive me nutty.

Didn't you just sink in a few thousand $$$ into this motor? Who built it for you cause you got hosed if it's having this many problems after a complete rebuild.

I will take pictures of the block because you can clearly see its been cracked for a while oh and my rocker arms are completly shot I thought it just had top end knocking do to the cam but they are tottatly worn out or are they sapose to be loosew are you sapose to be able to wiggle them you know twist them side to side im going to let you guys look at them an tell me. I always ignored the rocker arm knocking assuming its sapose to do that I mean it was all rebuilt. Perhaps it didnt get verey good lubrication but then again my hydrolic lifters would be collapsing right. Im using the rocker arms from the other block iv dubbed thee black block or bb. They dont twist side to side or are loose. An as for the IH moter I was just sore seeing as how there was a bunch of money dumped into it an I killed it with a bolt an the number 7 cyliner hole has a 3 inch crack in it:yikes: I just killed it the rest of the way
 
I'm with frog on this one. If the machine shop bored a cracked block, they suck. If they bored a block that had rusted to the point it cracked after the over-bore (no sonic test???), they suck.

I had "rebuilt" plenty of motors by age 19 using parts and pieces from others to get a running rig. Only one actually lasted. But I was young and dumb and money didn't grow on trees. I had good mentors, good advice, and eventually I learned how to properly prep and build a running engine. Good parts and good clean prep are the keys. You can't make chicken salad out of chicken shit.

If you are really pointing a finger at some deficiency IH had with their cylinder walls, you should look a little deeper. Seriously. This is an IH board, administered by an IHOnly shop. If "thin cylinder walls" were ever a problem in an IH motor, don't you think someone around here would have posted it up by now?

As far as valve train goes, depending on the style your engine has, yes some rockers (the boat style) will wiggle around a little when their valves are seated.

There is a lot of info on this board. Plenty of folks use what they learn here to bring old iron back to life. People in your club for instance (hint). If you are serious about swapping in an oil burner, then go for it. We'd all like to see how it goes. But if all you want to do is belly-ache about how IH motors crack cylinder walls or how they suck, then at least back it up with some facts and/or theories. This isn't pirate 4x4.
 
I have an engine here I will sell you for 200, it needs new freeze plugs but it runs. I took it out of the blue Scout because I had another motor here to swap in instead of dealing with all the plugs.
 
That sounds great but at the moment im swapping all the stuff from the rebuilt engin into my spair black block. Im hoping this will work if not ill give you a call.
