dont blast me if this has already been mentioned

considering that the v-10 is basically a 5.4 with 2 more cylinders, what is the reason it can not be a performance motor.

i would think that forged rods, forged pistons, arp fastners, heads ported by someone that can port 5.4 heads, a cam grind based on a performance 5.4 grind and a supercharger on top would make a great running motor. this is good unless the block itself if the week length.

the v-10 in the viper seems to hold up to hp gains.

i honestly think that faster likes to just pi$$ people off, he knows the 5.4 has more potential, i dont think he is running 14.9 with non-pi heads and stock cams, sorry just dont believe it. but hey i dont believe what others say either, espesially if there is an excuse attached.

 

faster150 just likes to disagree with what ever is said. he has nothing to do and he does not care AS HE HAS SAID. if you said the 4.6 stock makes more power than the 5.4 stock, both in the same body style trucks of the same year, he would be in here arguing that more cu. in. equals more power and bla bla. he doesn't have any friends and can't hold a job so he does the next best thing while sitting in his parent's basement.

but still, i get a kick out of it. so please don't ignore him, or he'll go away

I was looking at video's this weekend and now I have to agree that the 4.6 is the best engine to have just look at the damage this 4.6 does to a Hemi ram

 

wow that was REALLY sad, poor ford

 

is that you in the video faster150?

 

Hmmm - that's not how it looks when I race them with my 4.6.

 

Faster, you really are a tool. Seriously.

I just had to point that out to those who didn't realize this. WAIT! Faster is probably the only person here at F150online who doesn't think he's a friggin @$$hat...

BTW clown if the 4.6 was the almighty motor of choice for hp/tq , why would we put a 5.4 in our SDs, offer even larger V10s and diesel-based motors?

 

Ok, so I made it to about page 6 before I got bored of reading corrections to Faster150's posts. So now for an "on-topic" question. I am interested in a 6.8 stroker kit. And despite what was stated by a certain individual, I'd say less than half a dozen mustangs (including the prototype by ford, and one or two by now defunct BV10Motors) have housed a V10, I also happen to be a member and READ the mustang forums, so please don't spout what you think you know without doing the same.

So far I've gathered these basics tidbits:
-The ford cast iron block is plenty strong for anything you could want in a streetable vehicle.
-No one makes a "production" performance camshaft for 2v or 3v 6.8
-Other than fitment issues for a swap, the exhaust manifolds have already been engineered for as much torque as possible, headers will only hinder performance.
-This motor has a balance shaft to reduce vibration, is it possible that it too may need modified to match a modified v10?
-Split-pin crank = bad (but it is forged, so it should hold up for a little abuse), any real punishment is going to require a custom crank. Who can do this for a price that feels reasonable, and not gouge the snot out of you because you're asking for something "different?"
-3v heads are VERY good from the factory, minus moving parts, you can very well stick with the factory castings and still see good power.
-Long runner intake, awesome for a performance build, loads of torque. If you want forced induction (i.e. centrifugal blower or turbo), extrude honing the stock manifold "could" yield some airflow?
-Factory tuning leaves a lot of untapped power, with more airflow and more fuel, there seems to be a lot of bang for your buck still in there.
-Oiling, it's a mod motor, so I see no reason why what's good for the 5.4 won't be good for the 6.8.

Bottom line here, for those who want to skip the fluff in this post. You have the block support for going bigger bore (I'd want .030 over for sharts and giggles). Cams, someone mentioned getting blanks and having them ground. For real power, you need a stronger crank, if you're already paying for it, may as well get at least some stroke added to it, right?

Personally, I think this motor begs to be put in a mustang and flogged for 1320 feet at a time. After reading this, is there any disagreement?

 

bump

 

I totally agree. The only downside is the weight and the fact that it would be hell to work on in a Mustang engine bay.....

 

i disagee.

a swap to navigator 5.4 with the 4v heads make a lot more sense.
look no further than the performance on the ford gt. a twin turbo 5.4 4v could be a mild manner 10 second mustang and 9 would be a turn of the boost and race gas.

much better heads, no custom parts, lighterweight.

if i was going thru the trouble it would take to drop in a v-10, i would either do a 514 big block ford , or a 427 windsor.

i think it is a good swap for a heavy truck, not a 3200# mustang.

 

Brother, having read quite a few of your posts, I respect your opinion. I would like to add another opinion of my own though. The 6.8 is a modular motor, the 514 (I assume you're referring to a 460 stroker) and the 427 are going to throw even more fitment, compatibility, and design complications (aka, money) into the equation than I have figured for a V10 swap, though this is based on what I hear talking to local shop guys (if I'm way off base, well, it makes me happy).

Here's how I break down the cost:
1. Motor $2200
2. Wiring harness/ECU $350
3. Custom Chromoly K-Member kit Already own ($700)
4. TKO600 Trans $1900
5. Clutch/Flywheel $600
6. Driveshaft $500 (cut to length/balanced)
7. Diff/Gears/Axels+install $1000
8. Return style fuel system from 98 Mustang (???)
9. Manifolds (???) (Hopefully not the $2500 custom headers would cost me)

That should at least get the wheels turning

On top of all of that, aside from someone who's name I won't even bother mentioning, cuz they've probably "seen 30-40 every carshow," how many V10 mustangs have you seen? probably not as many as you've seen big block stangs.

Anyways, thanks for inputs, I appreciate all of them.
