kar-kraft carb upper on a navi lower from the looks of it.

 

Yup. Its made for a carb but a person could of course put a 90 degree elbow on top for a t.b., but then you'd getting extremely tall, thats why I was thinking of modifying for a oval t.b. off the side....

 

are there any torque specs on the flywheels for the 5.4? keep in mind im using an aluminum flywheel?

 

what about that billet stroker kit that srokes the 5.4l out to a 6.4. has anyone heard anything about that? pros? cons?

 

I second this question ... I've heard talk about it recently too. Any information will be appreciated. I want to get ALL the information I can before I start spending the bucks.

 

IIRC, people have stated that a stroker kit would increase the speed of an already fast rotating assembly. I assume that's a bad thing. Certainly would be sweet though. Do you happen to have a link to it, or was it just something that you heard about? Curious to see if that's with a standard bore engine, or if it has to be bored out..

 

I think I found what you are talking about: stroker crank for a 5.4L. Price is almost $3000 . Total cubes comes to 6.36L ONLY when you have a 3.740" bore (aka bored out block with bigger sleeves.) Assuming the one from MMR fits the bill, that's another $3300 that you have to tack onto the bill. Certainly not a cheap mod by any means. I'd rather do the 6.8 V10 swap, even though some don't think it would be worth the effort.

 

I agree ... $6,300 (+) is a bit steep for a street mod.

Yes, the V-10 would be cool ... but how practical?

I've narrowed it down to either the new 5.0 (larger bore) MOD block from FRPP, or the 5.4 engine. I understand the 5.0 block can also be stroked but I dont think Ford has done that yet. The 5.4 would be more attractive if it made the CID with a bigger bore as opposed to a longer stroke, but we have what we have to work with.

Decisions ... Decisions ... Decisions

 

Here is a website I've had stored for a while. Ran across Powerheads them when I was looking for Cleveland parts a while back. DSS Racing is on E-bay and in the magazines all the time. Both have stroker packages and Yall can get some sort of idea about price range(s).

The 5.4 already has too much stroke for the bore size for a real performance engine, putting in a stroker crank would be a huge amount of money for not much gain. Also, as was mentioned, the piston speeds in a 5.4 are already getting extremely high, a stroker crank would up them even more (think more distance traveled per engine revolution).



Both of those companies have their fans and also plenty of....ahem.... "non-fans". Caveat emptor.

 

The actual V10 swap itself did not sound too bad, with the exception of raising the trans tunnel a bit. The real bitch is the electronic aspect of it. People don't seem to like the V10 though, since it has a balance shaft and few aftermarket bolt ons are available. The balance shaft does'nt bother me though. Plenty of V6's have balance shafts, and I've never heard of an issue with one on a modded vehicle.

 

cons: extreme cost, zero expected gains on a 2v, super high piston speeds, non-standard parts that cost a shitload to replace. requires a very well done 4v top end to make any sort of good use of it and it's still pointless to add ANY stroke at all.

pros: bragging that you have a 6.4L. lighter wallet (about 10K when all is said and done)

5.4 is inexpensive to get into and no more expensive to repair than a 4.6 with its fairly standard rotating assembly. See above for the rest.

it basically serves to further unbalance the performance of an engine that's already got a nasty bias towards the bottom end and make it more bottom end biased.


Plenty of v6's are incorrectly labeled by their owners as being performance engines. Perhaps that could be the problem. Balance shafts add rotating mass...that's what's bad. It's no different than making a heavier piston and rod without making it stronger.

 

well my blower came with injecters...42's just like that kit. already have a fuel pump. all i have left to get is some little things i already have priceed and to get a heat extracter and brackets and when its all done with it would of cost me 2500 all together.

so much for not being able to piece a kit together for less

and when its all done i will be looking foward to havin that hole in my hood.

 

Thanks for the infomation. I guess the sames applies to putting a stroker in the FRPP 5.0 MOD block then ... ???

If that's the case I would be better off AND cheaper going the 5.4 route as you say.

COOL ... gives me another angle to approach the whole thing.

I guess what I need to do is start looking for a wrecked truck that I can get both the engine ans trans "pull-outs" from that way I have all parts and other MISC items that will reduce my parts-chasing later.

I'm curious ... Are there any compatibility issues with engine sensors between the 4.6 and the 5.4, and again across produciton years ... anyone know anything (or experience) anything about this ... ???

By the way ... the HMS 5.4 manifold looks impressive. Not a bad price neither. I dont know right now if I will be going the NA route or SC. If they are taking orders now to sell them cheaper I might just want to go ahead and take the plunge NOW and hopefully come out cheaper later ... ???

THANKS AGAIN !!!

 

No. Not the same at all. Unless I'm mistaken that 5 liters is from a stock 4.6 stroke (3.55 vs 4.16 for a 5.4) and larger (3.70) bore. The larger bore gives better breathing capacity, and a stroker crank in a 3.70 block would be awesome. Getting into some big money there though.....

 

ford doesnt stroke the 4.6 because rod angles wear out pistons. instead the COYOTI 5.0 IS A BB FROM THE FACTORY.

Right, the 5.0 is from a 3.70 bore with the current 4.6 stroke. FRPP offers two 5.0 MOD blocks; the FR500C aluminum block with the 3.70 sleeves (this block alone is $4-K) and the new cast iron 5.0 block with 3.70 bore (cost is so far around $2-K).

More than one company offers a stroker crankshaft that when used in either of the 5.0 MOD blocks above supposedly comes out to about 325 CID. I think Sean Hyland offers this package. Yes, it is pricey.

My concern is, would stroking this 5.0 produce the same "cons" and issues as with stroking a 5.4 as indicated below ... ???

why not just get a powerstroke diesel for that rpm range?

 

cons yes, however much less significant degree

5.4=long stroke/deck height 4.6

a 5.4 block with a 4.6l crank and an extra long custom rod would produce 4.6liters and would rev to the moon provided you have heads to support the 9000+rpm flow

by the contrary, you could put a stroker crank into a 5.4l taking the already silly 4.165" stroke of the 5.4 to something like 4.3"? you would effectively rev to like 4500 rpm lol

most "performance" engines have a bore/stroke that is "square" ie bore=stroke approximately

formula 1 engines generally have a much shorter stroke than bore, for example, they have a v10 that only produces approximately 3.0l, very short stroke, these engines IDLE @ 9000rpms...and make power to 20k

a 3.70 bore mod motor with a 3.70 stroker crank would make way more power than a 5.4l with a 3.552 bore and 4.165 stroke, but the 5.4 can be had for cheap, and can be built bullit proof for much cheaper, and the 5.4l when built right will out power the 4.6 everytime, with exception to the 3.700 big bore 4.6's, but if you give the 5.4 a 3.700 bore also, then it will kill the 4.6 just as quickly

 

There's a lot of debate on rod angles and no easy answer because it has just as much or more to do with piston height as it does rod ratio. There are plenty of factory motors with "poor" rod ratios that do just fine, and also keep in mind that when Ford designs it they are doing 100,000 mile durability testing, which is far beyond what the average enthusiast is concerned about.

 

I am going to replace at least the guides, maybe the chains as well. I am guessing the 5.4 and 4.6 have different chains?

 

Good question ... Does the 5.4 and 4.6 share the same cam gears, chains, pulleys, etc., ???

 

Cam gears are the same, chains are longer on a 5.4, I'm pretty sure the tensioners are the same, pretty sure the guides are different.
Basically you can use all the accessories from your 4.6, only issue is with a 2002 and up 5.4 front cover missing two of the power steering pump mounting holes.

 

I sure am glad you pointed that out to me because I would've screwed up and bought 1/2 the parts from one year and the other 1/2 from another.

I think I need to find a good pull-out with all bells and whistles to include the harness to the firewall of the same year Mustang.

I'm glad I susbcribed to this site. THANKS !!!

 

Well its really just the front cover aka timing cover thats an issue from different years, the timing components should all the be the same as long as they're for a 5.4 2v.

 

update: got the motor and trans stabbed into the car; just not perfectly on the mounts. its soo close. next weekend maybe..

 

Thanks many times over for the information and assistance.

 

well I've just made a small purchase for my vehicle

masterpower t70 turbo set up fully jet hot coated and bolts to factory exhaust location
60lb injectors
03 cobra tank with twin GT pumps

and i bought some aeromotive rails with line/fittings the other day

small transformation happening soon

 

1. See TurboX2 & co's responses below. Stroking a motor with a big bore isn't always bad. It's the preferred option. It's not an available option to us so we take the cheap way and get the big-*** tall deck block.

2. That's a matter of taste and $$$. You make your own call based on what you know of yourself. I think the 2v 5.4 is a perfect street motor for a 3200-4000lb street car. It's not too much and it's not too little. It's cheap to own and cheaper to play with than high dollar combos that are only marginally more fun in all reality.

3. Just the motor from heads down (you can go intake to oil-pan to keep it tidy and sealed). You'll take EVERYTHING else off your old motor... accessories, sensors, exhaust, oil pan, thermostat, radiator hoses, blah blah blah.

4. The HPS manifold is great and it's only going to get more expensive. I'd pick one up while the getting's good. He introduced it with a lower price than initially planned to stir up some sales.

the man!

great work man. Keep it moving along and it'll finish up before you know it.

quit it ... you're giving me wood.

 

If the power steering pump mounting holes are missing, what do you guys do to mount it?
