Sell the 150, buy a 350. There's your leafs, 1 ton axles, and 460 already there and ready to wheel. If you can actually just buy a decent one stock, no reason to spend twice as much to build a 1/2 ton into a 1 ton.
Then you just have to lift it and add tires and gears.

 

im from canada and right now most of the 350s that would even be worth looking at are going for like 2000+ and i dont wanna spend that much to wreck it. i found and old 78 with an sas front end and a 400 in it so i think im just gunna use that.

 

Good plan. I have a 79 I've been building, and IMO they're way more solid trucks. The 400 will put out decent power, but a 460 has the same bellhousing, so with motor mounts and exhaust it's an easy swap. Plenty of options for lifting them too. Just search around a bit in this forum and the 73-79 forum, and you'll find all the info you'll need.

 

i hear ya im in canada too! i wish mine was a 350 instead of a 150 but what can ya do...

 

You can come to America and get a real man's truck.

 

Or just look harder.... Look at my location... The I'm in Canada excuse doesn't fly with me...
I know where there's 2 different late 80's 1 ton 4x4 crews right now, one for $1200, one for $1500...

 

2g for a decent 1 ton?? thats cheap!!

The 79 is a good option but there again if it doesnt have the d60 front, it ain't gonna last more then one good stab on the throttle with 700hp.
You'll easily spend 2g building anything that ain't a 1 ton to be able to handle that power. If you plan to mud race with it, I wouldnt suggest anymore then 8 maybe 9" lift. I have 9 and am thinkin about bringin it down some already (800HP at 65mph in 200 feet ain't right when its too tall). A set of 38.5x11s on the front, and 38.5x15s on the back is a proven combo for mud racing, and I have seen guys somehow keep a d44 front without too many issues after a axle shaft upgrade.
I'm in Alberta as well so I know parts can be a pain to get when you're on a budget. Figure out exactly what the trucks use will be most of the time. If it see's 50% street and 50% mud, it'll have to be built alittle different then if its 100% mud.

 

700 horse 460--whats done to it?
whats going behind it? auto or manual-- 205 or atlas
id go with a 35 spline chromo d60 up front for sure with that kind of power and bigger rear-end
need to decide exactly what the purpose of the truck is and then get a good plan and parts list together and some money, extra money, and then some more money before buildin

theres good knowledgable guys here that will help but need to know what direction your takin

 

Well, 460's are stock with around 230HP. I'm told they can be built fairly easily to be around 500HP. Shouldn't be that much more trouble to get 700 out of it eh? Except around 700 horse i'm sure you run into troubles with a stock block.

 

yeah 500hp is easy to get out of a 460, and you can get a stock block to handle 800hp without much trouble as well. I have heard of guys running alot more then 800 on a stock block but I sure wouldnt recommend it LOL. Gettin 700hp isn't too bad, but it does take alot more planning and research then 500 does (not to mention more expensive parts)

But as it has been stated a few times now, figure out exactly what the truck will be used for and it'll be alot easier for everyone to help point you in the right direction.

 

Putting a 700HP engine in a mud truck is just plain stupid unless your doing some hardcore mud racing.

In which case, discuss it all with Hillbilly Rockstar, the only one I know of who's actually got a truck for that.

 

My 557 must be a pretty dumb idea. I have license plates and make beer runs once in a while. During the beer runs, I leave the 300 shot of nitrous alone, but I dont see any reason why this much power has to be left for race only vehicles.
I can teel you that most 700 HP claims are just that. Claims. While 500 HP is not too difficult in a big block, its not as easy as one would think, and 700 is not easy at all. Getting an engine, any engine well over that magic 1 hp per cubic inch starts to get crazy expensive. Lots of money, and when its not right on the dyno, guess what? More money. This is about cubic inches and cubic dollars. A 700 HP 460 is not very likely, I can tell you this from much experience. I run a few 521's and then my 557. (roller, high compression, P-51 heads, forged crank, crazy expensive rods, blah, blah. Its expensive!
How do we prove it? Line em up thats what I say. Mines not a competition truck, just a regular old truck with enough power to hold its own when I drop the hammer. I dont see this being a bad idea. Hop in the pass seat, and hang on, you wont think its a bad idea either. Make one pass, and you will be hooked, and want a large displacement bullet also. Drop the hammer and stuff next to you dissapears in a hurry, even in the mud.
"Objects in mirror are slower than they appear". Except my mirrors vibrate so much that I cant read that little saying that I had etched into the pass side mirror, and the things end up full of mud with one blip of the king demon carb!
Yeah, Im not convinced this was a stupid idea.

 

haha that post just made me chuckle

 

All i'm saying is that I think if you really do have a 700HP engine, which I do not believe he has, it seems like you can get a better use out of it in another application. You don't NEED 700HP in a mud truck. Not that I really believe that that guy HAS a 700HP engine. If he did you would think he would have answered the post asking what was done to it.

And Ed, just curious, what kind of gas mileage do you get?
Hahaha.

 

I carry a 150 LB nitrous filling station, and I use about 20 lbs in a weekend. Yeah, not much nitrous usage.
Now, I can burn up a drum of VP in a weekend. Price VP race fuels by the drum and you will see that this is big boy territory.
I dont actually have any guesses to even begin to speculate how many miles to a gallon I can get. Maybe 4 or 5 on the street if I keep my foot out of it, and just cruise around, but the thumper is difficult to keep at a low rpm. 'I likes' to stab the throttle for no reason whatsoever. Just puts a smile on my face that words cant describe. Stab the throttle on a big engine, and you wont need words either. Just a funny feeling that is unexplainable.
Maybe my mileage is not accurate, might be less, but I know I can use some fuel, but in this case, its not about the mileage, it is all about the fun factor.
