when your offroading typically you want as much tq as you can. but with mudding you generally are running high rpms and thats where you want hp.So the real quesiton is how much do you plan on spending on the build?You really need to think what the truck is gonna do the most because that's the general rule of thumb when you build a motor. Also you want to know your gear ratio as mentioned above along with tire sizes. And what tranny are you mating it to?All these factors play a role when deciding what to choose for heads, cams, intakes,etc...Are you using the factory computer and if so is it speed density or mass air flow?Give us all the info you can think of. If you are doing a complete teardown then it's best to do a purpose built motor.

OK Let me explain .............. this will be a 2grand max build till next yr
I have a 460 , f 350 .. 4 door xlt ext cab. i have the e4oD tranny with automatic locking hubs and 4 x4 stick on the floor.. bogg warner transfer case .. i already have a 37 inch lift with 40 inch swamppers on it... my gear ratio atm is 5.33 dana 60 front end with a 10.25 rear ...
my truck is at school in engines class atm.. doing compression test , head leakage test etc ...
The build i want is simple .... this is my daily driver... when it snows.. drive up to the mountains off road , go ski ing etc .. when it rains drive out to asuza and off road.. mudd bogg a lil bit ... pic below is azuza soo ... i am puting new heads on, not ported... need a cam and i do have speed density , but. i can get it chiped... also would lockers help ?

love the truck. you should check out Ford's built 460 crate engine for some inspiration. They list all of the aftermarket parts they used to make it a 521 cubic inch, 600 hp 600 lb ft monster.

Lockers and high rpm horsepower are not going to help you on rain slick roads and snowy mountain passes in a Daily Driver.
Limited slip will help some in the mud but isn't nearly so prone to swapping ends on the road.
More compression = more torque...to a point.
And in your case that point is the limits of unported heads, stock drivetrain, the speed density injection system and pump gas.
MAF would give you more options as far as cam choices and increasing the displacement.
What kind of gains are you expecting, or shooting for?

being that this is your daily driver i would keep the motor on the milder side of things.Something with a compression ratio of 10:1 would still be pump gas friendly. Your cam selection will be limited due to the SD system but I used one of the comp cams offroad 4X4 camshaft with good results.(with SD your cam must supply good vacuum).You will need new lifters with any new camshaft and will want new springs as well. Roller rockers would be a nice addition. Something with a 1:7 ratio
Your heads will be the biggest problem they just aren't good flowing heads. If you plan on keeping them then you might want to try and open up the exhaust side and have the heads overhalled by a good machine shop. A good free flowing exhuast is key as well. Long tube headers would be best but they don't usally mix well with offroading so look at some good shorty headers that are tuned like gibson etc..
It would be nice to upgrade the ignition to msd.
Keep in mind that 2k sounds like a lot but when building any motor it goes very quick.
Need more coffee......

*540 ??????? I need more info than that.Are the heads going to be factory besides your exhuast work?Do you plan on machining the block or heads?Using factory pistons?Changing the compression ratio or keeping it factory?

Get the crank, rods, pistons, bearings and head gasket lined up before you send your block to the machine shop.
Depending on the dish of the pistons, have the shop square and deck the block for the CR you are shooting for.
Be realistic, and realize there may be times you *might* have to buy sub-par fuel.
You might want to 'subscribe' to Scotty Johnson's templates and head porting advice at the Rein"Car"nation website. Rein"Car"nation High Performance / index 2
He has done very well at the Engine Masters and for a small fee will outline the basics and save you from hitting water.
Just my 2c

sorry to tell you this but lumpy cams and SD efi don't mix. A cam like that won't produce enough vacuum for your SD system even with a custom chip. You really should wait on a cam selection until your block is done at the machine shop and you have the crank, rod and pistons in. If you plan on using the stock valve train then you must first know what your piston to valve clearance will be because that will determine your max lift.Also if your using a high-volume oil pump you must check the distributor engagement to the oil pump shaft and ensure the clearances are correct.Some high-volume oil pumps do not allow the distributor to seat correctly it will bolt in but will not have the proper clearance and the distributor gear will not mesh correctly with the cam. Also keep in mind that depending on the cam you use you may have to use different valve springs one's that have a higher pounds per inch rating or duel springs.
