I've been kicking around what to do with a couple of my rigs lately. I've got an itch to build a motor (haven't done one is at least 20 years), and I've been thinking about stroker motors. Mainly because both rigs I'm working with need to be able to pull a decent load when asked, but still be good for average daily driving. I have both a 360 and a 440 to do this with, so we can discuss the attributes of either or both, preferably both. To help refine the discussion, let's begin with my first project. My 1972 International TravelAll 4x4.
I simply love this truck! It so well suits me and what I need for our family's needs. I like driving it daily, and eventually I hope it to be the wife's kid hauler. So, 95% of the time, this truck will just be a pavement pounder. The IH 345 runs great, but is really limited when it comes to upgrades. I want it to be my family outing rig. Hook onto a travel trailer and take the family (of 6) camping. Set up camp then lock the hubs and go adventuring up high in the back country. So I feel that keeping things mild is best. It has to manage some realistic milage numbers, and be able to handle loafing along on the dusty trail without extra attention.
I'm leaning towards the 408 and a 46RH trans, with a converted GM TBI set-up for fuel. Should give the torque I need for good towing, but not break the bank when putting around town or hauling the kids around for my wife. I know that the big block will also do that, but I'm concerned about the fuel economy. Can the O/D trans and the TBI really do enough to make this thing affordable to drive? I remember back in the day, we used to talk volumetric efficiency a lot. Is this still the case? What about going to the Gen III motors? I'm not opposed to that, but it would be a bit of a learning curve. I can go any direction at this point, I just want to make my decision wisely.
What say you? Thanks everyone!!!!!

What about a bone yard 360 Magnum with TBI? Or a 383 and TBI? The Magnum 360 heads are a lot better from what I here than earlier LA heads. The 383 would allow you to pick a middle size combo if you want a lot more torque. You can offset grind a 383 crank to 3.54 or close, put a set of BBC rods in it with custom pistons so you can use a more modern ring pack(less drag) and have a range of 388 to 420 cubes so the mileage is decent. The 383 based engine would have mostly shelf stock parts in case you ever need to go through it again. Same with the magnum, and you would have a hydraulic roller cam as well. The Magnum would offer a better valve train stock. Not having added up costs for the various combos, I would think the 360 Magnum ought to offer the best combo at a fairly low cost.

Quite honestly if it were me I would keep it IH powered. How about a 392 IH? If I remember correctly that was an option for those rigs.

We used both the 345 and 392 in IH small dump trucks, 8 to 10 ton loads. You could tell a substantial power upgrade from the 345 to the 392. I would think a 392 in the travel all would be all you want. Do a throttle body on it for mileage. They were good engines.

Yeah, I've thought about the 392, but I am currently ruling it out for a couple of reasons. FIrst, I don't have one. I'm trying to use up what I have laying around. Second is cost. Parts sources are limited and not that cheap. I'd love to keep it all IH too, but I wonder if for the foreseeable future, if something else in there wouldn't be better for my current situation. I tried to put up a pict last night. I'll try again.

Me and I will get burned by some of you, is the G3.
Ryan did a 408 or 416 stroker in his Ramcharger awhile back and the gas milage was terrible.
IMO you cannot get good milage with a 20-30 year old heads.
A boneyard 5.7 with a cam ,set of headers and a stock ECM with a tune will make over 400 ft/lbs of torque. Idle like a stocker, start in cold weather and give you 20+ mpg.
May cost you a little more at the beginning, depending on how you get your parts, but will be cheaper in the long run.

WIth a 408 or bigger motor, you will need to probably source a 4 barrel throttle body if you insist on going that route. Any stock GM unit won't cut the mustard. The biggest they offered was 670CFM on the 454, which Holley robbed for the first Pro-Jection kits. That throttle body is what I have on the W350 and even a mostly stock 360 will test the limits of that. It's already at the biggest injector made for that application and rated for 275hp, so nowhere to go besides adding more injectors. Also, the GM computer will have no provisions for overdrive control. I can't speak for some of the aftermarket or unlocked ones out there.
To save budget on the SB build, I would scavenge a setup out of a 94-96 Dakota. It will have all the wiring you need. Megasquirt 2 or 3 will more than handle what you are looking for. I built mine off the Pro-jection harness and added what I needed to make it work. At some point I will probably go to a magnum top end and 8 injectors in batch fire configuration, unless I end up going with a Cummins... There can be some issues with the low impedance injectors which require additional equipment.
I can't complain...for a 1 ton truck with 4.10 gears and overdrive,pulling the 2 big mountain passes it averages between 16-18 on the highway. I've yet to get it on flat land to see what it will do.

I would personally stay away from a cummins just because of the weight. Would really strain your suspension etc.
Not so much on this unit. A 345 IH is knocking hard on 800 lbs. A 4BT Cummins is a wash weight wise. A 6BT would add about 200 lbs.
If it was mine I would find a 392, add the usual bolt ons and call it a day. Barring that, I would find a late model 4V intake for the 345 if it doesn't have one already. They ran a Thermoquad OEM. An optimized ign and a good dual exhaust would round out the package.
I know you said you wanted to use up stuff you have but if I understand your intended use, you want to build for torque first and HP second. A 392 fits that bill pretty well out of the box and I can't imagine you can build a 408 for less than rebuilding a core 392.
If I was going to spend stroker build money on this, I would look seriously at a 6BT Cummins swap if it will fit in the hole. IMHO it's the only way you are going to get a cake and eat it too solution especially if you can make the 46RH/518 work with your transfer case.
If you wanted to keep it all Farmall you could put a 7.3 Powerstroke in it.

It's square and it's heavy. Gas mileage should be the last concern you have if your plan is to daily drive something like that. As somebody else mentioned, a diesel would provide best of both worlds, but doesn't sound practical.
Throw gas at it, or drive it less, not really a bunch of other choices, it's never going to be a Neon
