Good engines/engine combos that are got in 3/4 ton 4x4 trucks?

Since no one replied in the 4x4 section, I guess I'll post this string of questions here.
What are some good engines/ engine combonations that are good in old 3/4 ton 4x4 chevy trucks? I would like to have a good deal of low-end grunt and a strong mid-range. I was thinking a 350 with a edelbrock carb and intake, some-sort of a truck camshaft, cast-iron vortec heads, and ram horn exhaust manifolds.

But then there is another side of me that says big-inch motors. Either a 455 poncho, buick or olds, or a 472-500 caddy. I would like to know what you guys are running for engines and suggestions for what to build up or what engine to swap. Money will is going to be kinda tight (I think, depends what I get for the buggy and what I have to pay the old man out of it) I was planning on running a automatic tranny, if that helps any. Thank you for the replies. I'd really appreciate them.
-Jake

No substitute for cubic inches, I've had small block and big blocks in 4 wheel drive trucks, nothing beats the low end grunt of a big block.

Buy one with a 350 in it. Remove the 350 and make it a 383. I love mine.

yeah, ive been thinking of that, but machining prices around here are outragous. It cost $200 dollars at a local machine shop to bore out a 2-cylinder John Deere engine block!
NEED SOME MORE SUGGESTIONS!!!!!!!!

2-cylinder blocks are harder to machine because of the long stroke with requires some specialized(AKA homemade tools/knowhow) to get the job done. A SBC would be alot less!

What 2 cylinders do you have? I currently have a '49 A that I am going to punch out pretty soon for aluminum pistons, and I also plan to install '20/'30/New Generation fenders on it and a M&W Live Hydraulic system with a Charlynn P/S unit. I grew up running 2-cylinders everything from unstyled A's to 630's, Although when I started on my own I went to IH We lost our rented ground last year to homes and now I have JD, IH, and Oliver's ready to go when I find some more lang

We have kind of an old JD tractor. It is a 48-52 model B wide front with a 3 point hitch? It looks like a factory add-on thing by the the bars were perfectly bent, or someone had a really nice shop to work in. It runs good, she is bored over .125 and has a freshly rebuilt engine. It will be up for sale in a little while. It needs paint and decals, but it looks good with faded green and yellow, and a little rust too! I was thinking of painting my truck (If i get one) JD green with emblems/trim painted yellow.

TP from Cntl PA,
What exactly is a 6ATCummins engine? I've hear of 4 and 6 BT's, but never an ATseries Those4BT's are quite a engine for their size. My dad has one in his skidder, and that thing is a brute of a engine!

It is a 210 cube 6 cylinder............Designed by Onan for Gen-sets and built by Cummins(Cummins eventually changed a few items on the later ones like I have). It is indirect injected with glow plugs, but runs EXTREMELY smooth unlike a 6 or 4BT............Not to mention it will run up to 4000K without ruining anything. I went with it mainly because I wanted a 6 cylinder to fill the engine compartment, and I was told they smoke pretty bad.

Well, it sounds like a IH DT-414 at idle and mid-range RPM's, and if you crank it up so the Turbo is pushing alot of boost, it sounds like a BIG CAM Cummins on a hill in a OTR tractor Not to mention it looks like a steam engine

I will have a LONG post shortly on here about the project...........

You can't go wrong with a 350/SM465 or a 350/TH400 combo.

If you want low-end grunt, I'd go with a diesel. When I got my 72 C/20 from my uncle he had installed an 86 6.2 diesel in it. Nothing but low-end grunt. And it got 22 MPG with a 4:11 rear...

A few years back I helped a friend build what turned out to be one of the sweetest
engines ever for a 4x4. He had a '70 Chevy 4x4 van w/1-ton running gear. We built a
396 big block with:Edelbrock orig. Torker intake, 600 Holley double-pump, Crower Baja
torquemaster hyd. cam, minor headwork, Corvette exhaust manifolds w/2 1/4" pipe w/
crossover thru Hemi mufflers and a balanced lower-end. Also went w/low compression
flat-top pistons. This setup produced unbelievable low end grunt, decent idle, tire
smoke when you stomped on it, and ok to average fuel mileage on regular pump gas.
What more could a person possibly want??

Not up here in Maine with out a heat plug in the winter. Any GM BB will do about all you ever would want. I have run 500, 472 455, 425,427 and 396 ci
motors in trucks and they would kick a** over all but the VERY expensive built 350's. Way less money for all that torque with all the GM BB's.
Like already said, there in NO replacement for cubic inch displacement.

Nice to see another Maniac on board!

i've seen 455's and 500's pretty cheap in the local classifieds magazine, but i am a little weary about fuel mileage. You can't really beat a caddy engine, 495 ft lbs at 2600 rpm for a stock 500, but about 5 or 6 mpg. how bad are souped-up small blocks for fuel mileage?

1982 GMC 3/4 ton with Caddy 1971 472 with stock 411 gears automatic fully loaded with an 8' heavy slate pool table and heavy factory fiberglass cap went on a round trip from the top of Maine to Southern Maine over 770 miles on 78 dollars of gas when
it cost an average 1.62 a gallon. Or simply put around 16 mpg! The great running 350 only managed 12 on it's best day! Caddy motors should have been for trucks, GM messed that one up IMO.

You dont know where I can buy a flywheel for a Caddy so you can use a sm465 behind it,do you? Will a 455 flywheel bolt up, or some other flywheel?

If I knew that it would already be mine. They are about as rare as the correct bellhousing, Caddy, Buick, Pontiac or Olds for a standard. Most do not have a large enough center hole. For automatics they have an adapter plate for around 80 bucks. IMO you would have to find an old diesel (Oldmobile) that came in a Chevy 4x4 truck. I found one many years ago and mounted a 425 BB Olds right in a 79 chevy short bed truck with the Olds mounts bolted right on the Chevy towers. GM even had the extra holes in the towers for it. It was the easiest swap I ever did. There is a Lakewood bellhousing for an Olds that will work if you have 350 bucks for it. What part of the other Maine do you live in?
