I have a 2005 v10 excursion 220000mi on it. I did thehead gaskets at 175000mi. I have 33s and f250 springs on it.

my wife complains that it has no power. We love the truck drive everywhere in it.

When the head gasket went bad. I checked all the options. New ford engine 5 grand. Used motor all had high milage. Rebuild at a shop was close to 5 grand.

So I had the Heads trued at a shop. Cleaned the pistons and block sealing surface good and did the head gaskets.....its posted on here somewhere.


So this leads to my question. I run this trough my mine alot and cannot make a final decision.
been thinking of a cummins conversion. Get the power and more mpg. Right now i can get a 24v for a grand that needs a rebuild. Mine you i can do a rebuild no problem being a Former mechanic. Source out the machine work. I will get longevity and reliability out of that enngine. We do alot of roads trips by the way.
or regear the truck and keep an eye on the current motor till it givrs signs of going.


I cannot come to a conclusion.

is the 24v with blowby a good deal for a grand?

 

As I am now doing the same conversion, sort of, the answer would be no. You would be better off buying a low mileage, ready to drop in motor.

There is one 24V, VP44, locally here with 135K on it, complete with everything and you can here it run for 3K.

Also do NOT buy a 53 block for any amount of money.

I have seen this engine, though not heard it run. I bought a 12V from him for the pump. Pretty good guy overall.

If you buy one get EVERYTHING! I mean everything.

Trust me you will spend $$$ in a minute.

 

Also watch this guy.


He is right as it goes

 

I checked the utube video. 10 grand is not bad as i want to keep and enjoy my truck along time. I have owned it a long time as is and still love it just time for some improvements and to get it to the point of regained confidence in its ability.

i pmed you the craigslist add to get a better opinion of what you think. It is the only one here local except for a long block that needa a rebuild.

 

What gears you currently running behind your V10?

 

regear her to 4.56 or 4.88 gears...about $1500 to accomplish at a shop

or

find a 99-03 7.3 truck/X. do a mild refresh (seals, turbo wheel) and slap into your X. If you park rigs next to each other you can do the swap with no fabrication. it litterally is a bolt in


I know some people have done the Fummins route. But it isn't for everyone. Why not stick with Ford family for ease of swap?

 

They are factory 3.73 i believe. I know a gear change with my 33 inch tires will help. But there is still 220000 on my engine.
so this leads me back to a rebuild at some point in the near future. Which will lead to a cost of 4 to 5 k.

 

I'm in your boat with one of my excursions. I suggest gears, a 2009 thru 2014 used low mile E350 V10, and a well built transmission.

I have seen some 2014 E350 V10 motors with less than 20,000 miles go for under $3000.


Gears $1500
Motor $3000
Transmission $3000

And you good for another 250k miles.

That being said look for the little things like stuck rear brakes, and slipping trans or front hubs locked in. All these could reduce power output.

 

Sherman, to echo what the other guys have already said, I would go with a set of deeper gears now (4.30, 4.56 or 4.88) depending on exactly how you use the EX and enjoy the seemingly new rig the deep gears will give you, it's like a completely different truck.
Going from the stock 3.73 gears on my Ex to the 4.88s that I have now was night and day different. At first I was running 32" tires and with the 4.88s it was a real hotrod around town unloaded, very quick off the line and awesome throttle response at any speed. And it towed like a locomotive.
The after I upgraded to the 35" tires which gives me an effective ratio of 4.39 it is still much more responsive and quicker than stock and it tows our heavy TT way, way better than the 3.73 ever could.
If you don't tow heavy and are just using the Ex as a daily driver with some highway trips occasionally I would look at the 4.56 gears with your 33" tires. That should provide a serious performance upgrade. If you do tow, then consider the 4.88s if you don't see too much unloaded highway travel as the MPG do suffer a little with the deepest gears, I was only seeing about 12 MPG highway with my 32"s and 4.88s. With the current 35"/4.88 setup and 4" lift I'm getting 12.5 MPG at 65 MPH on the Interstate and 8 to 9.5 MPG towing the 11K TT on the highway.
I would also recommend a few custom tunes from 5Star to compliment the new gears, I always run either the 87 or 89 Octane Performance tunes when towing, they do wake the motor up a good bit and they make major improvements to the transmission strategy, well worth the cost to me.

 

The labor will be about the same, as in the end it's all work. As to ease, probably just as much as the cummins swap.


The cheapest route as pointed out is to just replace/rebuild your V10 and re-gear it.

Bottom line, do what YOU want to do.

 

Forgot to add, if you do a cummins swap and stay with a ve or p7100 mechanical pump you can also run alternative fuels, diesel, cooking oil, UMO, etc.

 

Will a medium duty 6.7 and allison fit in an ex?
Will the bell housing be to big? Sae 3 i believe.

 

As I understand it, the 6.7 is the same size as the 5.9, but that 6 speed allison trans is big.

You need to google up that swap, there are stories about it out there. Also google up cummins conversions and look at specialists.

Going to go all out huh?

 

yeah i think so. ... so got a lead on a 6.7 and allision 1000 for 4 grand minus ecu. Engine is suppose to be new.

will try and look at them tommorow.

will do the following. Check all fluids sight and smell. Check to see if engine is locared insode or exposed to elements. Hand turn over engine. Look inside intake for oil or rust..... take pictures for forum. Check trans fluid sight and smell.

What I know. Engine and trans require a adapter to mate. Engine and tmc can talk. Combo will fit in out truck. Combo will fit transfer case with tailshaft mod. Have companies that make mod parts.

Any advise ladies and gentlemen?

Please excuse punctuation and spelling. Big fingets small phone. Very little sleep.

 

Just to reiterate, you will need EVERYTHING to make that engine work in your vehicle. Don't be complacent by the low initial price. You need to get it all. If its a long block, be prepared to spend.

Yeah, 4K is cheap for that package, but I be you will spend another 4-8K getting it running, plus installation labor.

As I am doing mine, $100 here, $50 here, $250 here, $20 here, it all adds up, quicker than you can imagine.

Also a good question is WHY did they take it out?
