This is my first post so go easy on me :-) I have been a Ford guy for years and went to he dark side and got a Chevrolet 1500 and all I can say is what a turd it was.(no offense to Chevy lovers) So I was looking for a F150 and came across a 99' V10 F-250 Crew Cab Lariet that I had to have. I dont tow anything except a few dirtbikes in the bed.

My question is what should I expect accelration wise? The truck has 135,000 highway miles on it and is in fine shape. I don't know what to compare the truck to so I don't know if it is perforing as it should. Should I be pushed back in the seat when I floor the truck?

I am going to chage the fuel filter tomorrow and see if I get more power.

 

I had a 2000 F-250 Crew Cab Lariat a while ago. I think the engine was rated at 275 hp stock. The truck had some nuts but it's a lot of weight to get movin. I wouldn't expect it to throw you back in the seat but it still isn't slow.

After I bought a new truck I ended up putting a custom supercharger, lightweight engine internals, re-bored it, converted to 3-valve, headers, ram intake, and a few other tweaks. Ended up with over 650 rear axle horses. That truck would smoke em'.

I've got 100,000 on my 03' F-350 V-10 now. Still runs like a champ, but I just traded up to an 08' w/a 6.4.

 

You'll need to expand on that if you would please.

Converted to 3V?
Lightweight internals?
Custom SC?

 

I am real interested in the V10 "ram intake" mod on the 3v V10 heads on a 2000 motor

your post suggest you are not impressed with the power of the 415 CI 2v V10 1999 motor .... Crew Cab Lariat and probably 4x4 is a real heavy truck and the olde 275-295 HP motor has a challenge motivating all that weight through 3.73:1 gears...

I assume you bought the 1999 truck because of price

Thus you are probably not in the position to spend $3000 to $5000 dollars to make it have 30-60 more HP....

Best bang for the buck will be stock diameter tires properly inflated and a gear change to 4.10 or 4.30 @ $600~$700 pre differential

INtake mods $300~$500 ...... maybe 5-9 HP
Exhaust mods $300~$1600.....maybe 9-14 HP
Gear mods $600~$1900..........no extra HP but much better use of what is there
Chips and tuning $500~$700... maybe 7-21HP (usualy with high octane fuel)

when all said and done you may get an extra 40 HP

If you really like the handling, comfort and all other characteristics of the 4 door V10 powered SuperDuty.... save yourcash, drive the neat old truck..... watch the ads and eventually find a 2005 3v V10 5R110w truck for real good buy in prioce... $3 to $4 dollar gas will have more and more of these things being sold for real reasonable prices!

My signature truck was MSRP at $49~51K---- I paid right at $38K and at 3 years old it's book value of $23K and I would be lucky to get rid of it for $17~19K--- I am not looking to get rid of it!

 

TM2K...welcome to the site. Your truck is not an overpowered monster but it has alot more grunt and a nice acceleration to it. Expect around 8-15 mpg. city and highway. It is a heavy truck but will do whatever you throw at it. Just enjoy it and maintain well. Change the plugs right away.

 

HUH???? You managed to rebuild the V10 w/ "lightweight internals", convert a 2V engine to a 3V which is like a feat in itself from what I've read, AND put a supercharger on it???? You need to tell us more about this, because I'm not buyin' it. Sounds like bovine fecal matter to me........

 

Thanks for the warm welcome. I just changed the fuel filter and have not driven it yet. I want to chenge the plugs but am scared because of the plug spitting problem. Is it rare or somewhat common?

I have a 99 crew and it has 430's. It has really good power. Check your door sticker what kind of rears you got.

RARE!!

Prevention is the name of the plug spit game... steel plugs in aluminum holes..the early plugs were NOT coated so they rusted and corroded in the holes... some were too loose form the factory and some were too damned tight! if you have NOT blown one out then all you really need to do is find the step by step post here in this forum and get after it.. new plated MC or autolite plugs, new boots...you need some sort of compress air source and a dab of anti seize compound...search this forum for plug replacement there are several excellent posts

 

I sent it to a performance shop, they rebuilt it from the block up. Lighter piston heads and crank shaft. The 3v conversion was just from an 05' V-10. The ram intake was just mainly aesthetic because it had a supercharger, but it is a true functional scoop.

I just had someone else do all the mods. I wouldn't be able to get you the exact parts and specs of everything. Sold the truck last year to someone in Florida.

 

That is a real shame SouthTexasDiesel...

Now a whole lot of us V10 motor heads are thinking you are really stretching the story some...but perhaps you just have a LOT of money and let some shop sell you a supercharger and claim all the other crap....now we will never know fer sure...

Sorry to bust on a felow Texan...but your claim is really really out there in my book

Sounds like it was all show and no go...

Any chance you remember the name of the performance shop and name of the head wizard that you wrote the $15,000 dollar check to? Maybe even a phone number or internet address....
