i want to dump some money into my truck i have a 78 bronco with a 400ci so the 460 is a easy swap i hear but anyway the 400 starts and runs fine every time but is tired so when i am in deep stuff for a while it starts to bog out and 4 high just does not cut it but i am not afraid of it dieing anytime soon on me. now i can get a cheep set of 456 gears for my truck would this bring it back to life enough or is it not worth my time and should go with looking for a 460 to swap in gears i think would be more cost effective right now because if i am going to be swapping to the 460 i may as well make sure its not going to be giving me any trouble soon down the line because i do drive my truck hard

thanx[cheers]

Dont know much about your truck (mods) But if you drive it hard
that dana 44 front is a weak link ,can spend alot of money for repairs
and mods on a 44 and it just keeps braking , mite a good start to
find a 60-70 .

i am only running 38.5 right now so doing the 60 and 10.25 are not worth the money to me right now don't get me wrong they will come but when i can pick up the 456 gears for as cheep as i can that includes spools front and rear or grab a 460 and maybe take it a little more ''easy'' on the truck i just wanted to get the most cost effective way of getting my truck to make it further than it does now without having to worry about it bogging out on me near as easy

Hey, the cheapest best upgrade you could do: USE LOW RANGE

I shit out chromoly shafts with 37's a v6 and a truck that weighs a quarter of what yours does. so dont think that your stock 44 an even a modded 44 will hold up to 38.5's

Well as far as adding weight I don't see how a big block 460 is to much more heavy than a big block 400 and I don't know what your doing with your truck but I have had mine for almost 3 years and wheeled it hard every time and the only thing that I have ever broken was a drive shaft and yoke also like I said before 4 high is not much good so it is always in 4 low so I don't need the attitude I don't meen to be rude but maybe you should spend some time reading what people are saying before you add your 2 cents worth ''kinslayer'' anyway the only reason I asked this question was because the truck is not performing up to my standards in the power department I don't care if I have to fix a front end here and there its a quick and easy job I just wondered if I geared it if I would be able to spin my tires better- example being gearing making up for what the motor is not pitting out or if gears wheRe a waste of money and just go with more power. But everyone is telling me to upgrade my front end and yes thank you and I also agree I do plan on it one day but its just a weekend toy so not afraid of breaking it and its been more than good to me so far but putting a big 60 or whatever won't help the fact that I'm just trying to get more rotation out of my tires but thanx for All your input I'm not trying to piss anyone off

Me personally I would do the engine now because you will eventually need to replace the engine from what you described and you might as well have a solid powertrain. Also everyone eventually moves up to 1 ton axles so I do agree with others that say you shouldnt throw money at the front axle if its only going to be replaced in the future..

Maybe weld up the front and rear diffs and do the 460 swap... Best of both worlds?

i dont think its technically a big block, nor small. its just a 400. and it does weigh alot less than a 460 i think around 200 pounds less. and 460's just gulp more fuel than you can throw at them, so i say keep the 400 till it blows then rebuild it. and of course 1 tons with some sort of locker or spool or welded diff and gears and hydraulic assist steering is nice to have with big tires.

of course it all costs money and time and hard work, but just as the saying goes you gotta pay to play.

If you are running it in mud you want to spin the tires FAST so they clear better and keep you going

going to lower gears may stop your engine from bogging but it will slow your wheel speed and will not improve your ability to get through the goo


Just my .02 cents [cheers]

One common factor of any body that wheels , is your always braken
it or mod it and the money tree runs dry . You made a 44 last 3 years
with 38" is great , seen toy axles with 44" , most people arnt that lucky
Look at some builds on here and pirate that are simler to what you want
to build , spent money on parts that are needed . Have fun !!

Fair enough I guess ill start with the 460 and then just wait until the front end gives out and then go for the bigger axles I was not sure if the gears would slow my tires or not anyway thanx!

but spending the big bucks to buiilt a 460 to take the revs may be a challenge, and less weight on the front is also nice. Buy a gasket/re-ring kit and a lumpy cam and spend the up-coming winter building yourself up a fresh-ish 400cid. The less-mass of rods/pistons going up/down 7g a minute on a 400 sounds like it may last a little longer than the 460 would.

A 400m hitting 7000rpm is mever a good thing. Have you concidered building up a 351w? Lots of parts are around for them, a lot cheaper to build and a high hp to $ ratio.

400 is the way to go imo, built properly they rev quicker weigh less and the most important part, use less fuel.

the 400 is a 100 pounds lighter then the 460 and 400m got 7mpg and my 460 which makes 450hp gets 12mpg on the highway and has way more power

thats bullshit

lets do a little comparo,

my truck 79 f250 on 44 inch boggers, 5.13 gears, welded rear end. 400 cubic inch with a 4 barrel edelbrock, edelbrock aluminum intake,cheap headers and a 2 into 1 cherrybomb exhaust. 4 speed with granny low 1st gear. pedal to the metal almost all of the time, unless im trying to make 1/8 of a tank last a couple days.

my friends truck 87 f250 on 44 inch swampers,4.10 gears, open rear diff. 460 cubic inch with a holley 4 barrel carb,stock intake, stock exhaust manifolds with a 2 into 1 flowmaster 40. 4 speed with granny low. doesnt matter whether he putts around or floors it, the damn thing eats more gas at idle than mine does WOT

i put $30 in my tank and drove for 3 days to school,work and around town. when the insurance ran out i shook my tank around it was empty. my buddy would have to put at least $65-70 to do the same amount of driving.

design problem is with the 385 series motors and the humps in the exhaust ports.

aint nothing wrong with a 400m

Ugh now I'm confused everyone has there own opinion so I guess ill just have to buy a F350 with a v10 then ill have big axles and big power! Ha ha and you can get them cheep these days ;)

460 stroke is 3.85"
400 stroke is 4"

piston acceleration and deceleration forces are greater on a 400 then a 460 at same rpm

the 429/460 family is designed for rpm, more so then the chevy big blocks

I've run the 44 lots too with much dismay! 3 sets of wheel bearings a year daily driving and thats with regular service. wheel joints and axles don't like 38's unless they are 11" wide but still hard on parts in the bush. I've spent a lot of time rear wheel drive only. Spend your money where it's absolutley needed preventitivly (dana 60 front) or maybe tame you tires down a bit lest ye be stuck again... and again... and again but if you stay with the 44 truss it and put the stongest gear you can find. If you motor is reliable leave it be your drivline takes more abuse on the trail and is the most common cause for spending the night on the trail

google 351M-400 performance awesome info! i have had 460's and 400's, you cant pay me to run a 460. i have been beaten the hell out of my 400 for 7 years! a buddy of mine has a 400 (which IS a small block, 460 is a big block) 9.0 comp pistons, 268 cam, cleveland heads, 670 holley and the performance is AWESOME! ya i would gear it first, if you think you can make that d44 hold up. its possible depends on how ya wheel! good luck! if ya got any questions pm me i've been work on 78-79 f-trucks for 20 years would own anything else!

those humps actully improve the scavaging efrect and if you touch them lightly with a die grinder they flow a tremdous amount of air

9" rears are for cars!!!! blown many axles, gears, and bearings. Will never wheel on them again unless under a sami. Save yourself the headache. That spool will eat axles.[j]

Unless You have a diamond mine, throw the 400 off a bridge. go to the pick-n-pull and grab a 460. they are lighter. you'll be way happy
