I have a 460 4v with 69000 miles. I am bouncing around the idea of a rebuild. What are the best options for semi-performance parts, i.e: Heads and Cam. I know that a better intake and modern 4bbl with headers will help but what are some of the performance mods that you know of?
Second Question:
Of course I have the HD Dana gear in the pumpkins but what about going with a set of newer axles and more highway friendly gears? Would newer super duty axles fit a Highboy? Would the benefit of 3.73, etc gears be worth the investment? I would like the rear discs as well.
Third question:
Does anyone make a kit for the steering mod or do we need to source the parts for ourselves to switch to the newer steering mod?
Fourth and last question: is the 355 a FE motor or is that something different? The 460 is a 355 series correct?
To give you the best answer we need more information. Like tire size, transmission, and intended use.
1: performance-
460's are capable of quite a lot of power. An easy way to accumulate all(or most) of the parts you need would be to buy a stroker kit. Cam will depend on your usage. Aluminum heads or dove heads will flow better and yield more power. A single plane intake with a properly sized carb will help power. Headers are a necessity with a performance build. A hot coil and ignition module will help things run stronger as well.
2:gears/axles-
This depends greatly on your current setup and intended usage.

The engine tips were very helpful, Thanks.
As for usage, it will not be a tough working truck. Probably won't leave the pavement very often. I just wonder if switching out the 4:10s for something more efficient wouldn't help? Also the question was really: Is it easier to update the running gear as it is or is it easier to just install newer running gear? My setup is mild, 460 (stock) with C6. I have no idea what my transfer case is.
It is not difficult To swap gears. It's also more cost effective than a new axle. Gear ratios will be recommended by what tire size you plan to run. There are a few charts that will show up on Google for what gears work with what tire size for economy, balance, and power.
So far, I have learned that I have a 385 series motor.
I have learned that there are options for building it up a bit.
It is easier and more cost effective to switch gears than switch axles.
So far what I still have questions about:
Why I don't have a gas tank in the cab like most highboys.
Whether there is a kit to switch the steering to a 78/79.
Thanks in advance for all the info. This forum rocks!

On the gas tank question I don't know for sure but could it be possible someone swapped beds on your truck and eliminated the cab tank?
Kit: I don't recall seeing anyone posting of one. I believe they take parts from later years.

Visit the tech thread compilation sticky for info on mildly hopping up the 460. A torquey cam, 4V intake, and 650 cfm will garner upwards of 400 hp on about a $1500-$2000 budget.
That 460 Site is Rad!
I am a little weirded out by the gas tank situation. I'll have to call the original owner and see why the tank was moved. Not a big deal, it gets gas the way it is! LOL (And ALOT of it!)
Looking at some cool heads, cam, Intake, headers and carbs for the rig. I just need to find gears.
