Eh I wouldn't say a turbo is TOTALLY out of the question. Have you ever seen carlos' beamed cummins? Or dirt designs blue duramax? Those things are crazy and are both turbo diesels! Also motolifes old ford has a 2jz in it if I remember correctly. That thing ripsss ha

 

Diesels and those 2jz's lend themselves to turbos though. No one ever supercharges those motor for a reason. Smaller displacement motors respond a lot better to turbo boost because that they don't have to expend energy/power to run the blower belt. For diesels, the same thing kind of applies, but they're built tough as sh**, so they can handle (and need) more boost than a blower is going to provide.

That's the first time I thought about why diesels are never supercharged, but that was what I came up with just thinking about it logically, so that may be incorrect.

 

IMO, one of the most potent motors to ever leave Detroit was the Ford FE big block 427. The 426 Hemi was probably the only other normally aspirated engine to out perform Ford's 427. (Keep in mind, these were cam-in-block, NA motors.)

Since you're wanting to do something using newer stuff, and not have to deal with squeezing a big block in, I'd say stick with the 5.4. Others have mentioned stroking it, but I can't comment on that.

What I do know is that P=omega*T, which means that, if you can hold the torque curve fairly flat while you increase the RPM's, then you can make more horsepower. In the case of the 2V 5.4, you have overhead cams - no push rods. That means you can twist the pi$$ out of that thing without fear of breaking a rocker arm.

My take is that making 8000+ RPM with one of these should not be that difficult, and that should give lots of power without having to radically modify the motor. I'm thinking, have a machine shop go thru it and clean everything up while adding some more aggressive cams, then get someone to tune on it, and you'll be roasting tires at every turn

Of course, I'm mostly talking out my @$$, but there's no doubt in my mind that the 5.4 2V is a very good starting point for hot rodding.

(And if I ever get my last few kids thru college, I might just have someone put some cams in my 5.4 2V!)

These modular motors don't make much power N/A you need to do a stroker kit on them to get anywhere. There is an article on a 400ci 4v 5.4 based stroker. over 700 hp and 650 ft/lbs bla bla bla. If i knew its specs id tell you. http://www.popularhotrodding.com/eng...sday_coverage/ your 2v limits you even more. A lot of people on this site say that 2v and 3v motors are all you want in your trucks. But what are the 5.0, 3.7, and 3.5 motors? 4v motors. the 6.2 is the only 2v motor offered today. You don't want to go FI which i think is the best way to go for you, but i cant say its the only way either. I've learned a few things about the modular motors since ive moved to the mustang forum im part of.

 

Truth!

I was thinking a 32-valve 5.4L swap at a minimum should be in the works. I know the old school thinking here is that OHC engines are high-revvers and OHV = low end torque, but folks seemed to love the high end on LS1-based engines and nobody accuses a 2-valve head 5.4L of being a high-end screamer. Next thing you know, the old 300 will get love for its 2000 RPM peak torque figure, but won't remember the fact that is makes nothing but noise beyond that (unless they've actually driven one). When you say your prayers, thank the Good Lord up above that we have the technology to do better. The Intech still has the same low-end grunt as a Triton and still breathes better on the top. Bonus points!

16 extra valves and two extra cams and some fine tuning can only help in OP's case. All the comments I've read comparing stock 2v vs 4v 5.4L says the 4v trots away from a 2v easily. Even at highway speed.

Have at it.

 

so no boost, motor gone through and it should put out some serious numbers? realize I have 4wd and will be running 37 or 39 inch tires. this is going to have a big draw on the power too.

I do want to go FI, I don't want to be at all carburated and mess with that. a buddy has a carbed bronco that he rock crawls and it cuts out on him if he tips too far left or right. that sucks.

so are you saying the 5.0 3.7 and 3.5 are more low end or high end power motors? whats the correlation with 4v vs 2v? 2v low end 4v high end? 2v better with supercharger? 4v better with turbo?

whats intech ha? so I should look for a 4v navigator motor? then do what with it?





The original idea here is I want a NA motor that kicks ***. mine doesn't and from what I've read wont ever no matter what I do to it unless its force fed. the idea stemmed from a friend who has a cam-ed escalade motor in his ranger. its fast as hell and is all motor. I actually like the 5.0 idea. I never thought of that, and I will look into getting one and how available they are, I have no idea what trans they run and all the electronics involved. when I looked to see what some other trucks run I got that a few of them ran a 442. is that a big block? how much bigger is that then my motor? old technology?

 

Anything your rock crawling with should be FI, when your straight up and down that carb with starve for fuel everytime. FI you will always get fuel to the motor no matter what angle your sitting at, unless he is on his roof lol. I was once in the mustang world pretty heavy and will be getting back into it very soon but we were always ripping motors out and doing this and doing that to them to try and get more power. The best thing I have ever done to one of those motors for power and reliability is high perfomance internals. I duration cam, upgrade heads or at least valves/rockers, big fuel and air supply and try to get rid of some pullies.. Other than that I dont know of anything you can really do with these motors without a big stroke or big bore? I still vote on Coyote swap!!!!!

 

coyote swap would suite you best! But it's an outrageous cost to do so. You may be better served to go S/C to get the gains you need.

 

A crate Coyote would kill you money-wise, and I imagine the used ones are still too new to pick up on the cheap. The 5.0 will bolt up to your 4-speed trans, but I heard they suck without their 6-speeds.

I may have missed something, but why exactly do you not want a blower? Other than the fact that GMs go NA and still kick ***.

As much as I hate to say this, I don't see THAT much a problem with you throwing an LS motor in the truck, especially for a mid-mount. I bleed blue, and always will, but go with what gets YOU the best results for the least amount of money for YOUR truck. And that applies to everyone really. As long as it's American, I can't complain anymore.

 

The term "FI" here means forced induction, not fuel injection.

What about a V-10 swap?

 

Good point, I noticed but I see others took it as fuel injection. Let's say FI = forced induction; EFI (the correct term) = electronic fuel injection

I don't think he wants a huge motor back there though and the V10s are still a little pigish IMO

 

I wanted to see what I could do NA before I went FI. That way It would be strong naturally and if I ever wanted to I could boost it. Iooked up a coyote motor and they aren't exactly cheap. But they do give a good platform. If I can find a crashed stang or f150 I might go that way. You know what I did find were some semi cheap 6.2s! No idea how big they are but I'm going to look into it. Anyone have any info on the 442 I talked about? And I guess can someone answer a general question I have, what is the difference in our ford motors between the small block and big blocks? Besides size. Mine is a 331 if I'm correct, when do they start classifying big vs small? And I don't think the v10 would be a good idea. They're not exactly race cars ha. I followed one guy who centermounted his 2wd f150. Threw a vette motor in and it apparently went in really easy because it was much smaller than the 5.4. Don't know if he ever finished it but it looked promising.

 

Ya I didn't catch that the first time around so I thought FI meant fuel injection. My bad

 

The 5.4 is a stroked 4.6. I'm not sure stroking it even more is a good idea. If I wanted a lot more power, I'd go with a supercharger, 3V 5.4 with supercharger, or a 3V V10, I suppose.

But after a while the cost gets so outrageous, you may as well buy a fairly new or new SVT Raptor!!!!

 

Who makes the 442 or what is it? I can't think of anything except the Olds with the name 442.

There are 61.01 cubic inches in a metric liter. So the 6.2s are ~378 in.^3. But all that matters with "size" is the size of the block, not really displacement. Because the displacement is the volume of all the individual cylinders combined. So a 4.6 and 5.4 are essentially the same "size" because they share the same block. I don't know what platform the 6.2 is, but one of those may be a really good choice, cause a lot of the fleet trucks that aren't diesels have them, and there are certainly a lot of fleet trucks lol. I don't know what Ford considers a "big block," but I think the 6.2 is likely still a small block.
