Anyone consider a ford inline engine?

[user name]

I was wondering if anyone dropped a ford 4.9 I-6 in a jeep?

I have a cherokee, nice vehicle but I have more experience when it comes to my ford, sorry. Please keep in mind, I am not bashing the 4.0, just exploring the idea of an alternate powerplant.

I keep reading what everyone is dong to stroke the 4.0 and the end results, seems the TQ output is less than I would hope for, maybe it has something to do with the only examples I have seen were modified stock efi, what results do people get with a carb 4.0 thats been stroked? Don't misunderstand, usually an efi has more tq output but seems when people modify the stock efi vs retune, its not always the case, there are exceptions.

Reason I bring up the ford is, the ford can be massaged enough to make 300hp and 400tq, flat tq over a decent rpms range at that, with pretty standard engine modifications/ port work, all with a very mild camshaft, albeit carbed, unless someone wants to screw around with a stand alone eec box to replace the POS efi system.

The ford has a proven auto three speed tranny (c6), you can modify it fairly easily to get a lower gear for first. Would think it to be ideal of offroading.

I guess what sparked this thought, my wifes cherokee is peppy with that little engine, considering the stock power ratings and being a gearhead, couldn't help but wonder just how nice it would feel with a drastic boost in TQ and with a shot of HP. I followed along as many have stroked their 4.0 and posted their results and I thoght, I know where I can get a little more...hmmm...again, no offense.

I understand their would be a weight issue but also feel it wouldn't outweigh the additional power potential.

Just thinking hypothetically, again, this is not my bashing the 4.0, so please do not take it that way, simply exploring alternate engine options. I read where people discussed the installation of the chevy v-8's with reasonable feedback and felt this discussion would not get out of hand.

thanks

personally, i am a firm believer that anything is possibel, and I love I6 engines.

Before I found the great white i was looking for a Ford 4.9L F-150, but they are pretty rare in these parts.

I think that the amount of fab work that would be done would out weigh the benefits though. Its not klike the Jeep is crapping out on you right??

If you do do it, post pics, I would love to see it done.

I love the 4.9 engine. A very nice powerplat stock.

I would never own a carb'ed vehicle though. The extreme off-camber situations I'm in all the time would really suck with a carb.

I would do the swap in a heartbeat, if I dodn't live in CA and have smog issues to deal with.

Food for thought, while its a bit overkill, the old ford inline can be bored and stroked to around 330 ci.



Cool, noresttill, I am an inline enthusiast as well, doesn't matter the make, I like it. No plans on modifying my wifes jeep, just a hypothetical, now if another cherokee becomes available, it might be something to consider.



As much as I dislike a TBI setup, I would almost be tempted to go that route, using an otherwise carb setup, to take out usual concerns a person has with using a carb offroad. That an the 4.9 upper intake is one weird looking SOB.

That engine is without question is a great powerplant. Some careful tape measure work is in order before considering it for an XJ transplant. I recall them to be both long and really tall compared to a Jeep six.

i have seen them swapped into older CJs in place of the old 258

I was looking at one of these in a junkyard (I always see TONS of Ford 300ci 6ers) and I thought to myself "this thing is huge, would it fit in an XJ?" anyone know. It just seems like a massive chunk of American steel. On the other hand, someone I know had one in an 80s Mercury Zephyr and it fit. My grandpa also had a one in a pickup he had, I diddn't like driving that truck though. I wasn't racy but it did have torque. Most of all I don't like how Ford manual trannies shift of where the gears top out at in their trucks. I agree I like the engine and I6ers in general but I'll leave it for the pickups, I'll keep my Jeeps AMC I6.

The Ford 300ci I6 (4.9L) is certainly an engine worth considering as an alternative to stroking the 4.0 beyond 4.7L if you can find one (they're pretty uncommon). I believe the Ford has a taller deck (and longer stroke) but is marginally lighter, so if it does fit in the XJ engine bay the hood clearance is gonna be pretty tight.

You mean in your location, correct? They were put in production vehicles for over 30 years in the U.S., they were no longer an option in production vehicles after 96 (limited heavy duty models in 97) but they are still in use today, in commercial equipment: generators, woodchipper, air port tow vehicles, etc.. Better yet, a company is trying to capatalize on this fact and reproducing these engines to date. Good news, in stock form, they are strong.


Here are some specs on the 300 engine:
300's weigh about 490 pounds.

300 DIMENSIONS rough dimensions:
FRT-FACE-OF-BLOCK to REAR-FACE-OF-BLOCK: 28.56"
OAL (FAN-to-CRANK-FLANGE): 36.65"
HEIGHT CL CRANK-to-TOP-OF-BREATHER-CAP: 19.12"
HT OIL-PAN-to-TOP-OF BREATHER-CAP: 27.17"

Bore/stroke: 4", 3.98"
Rod length: 6.21"

The stock rods are forged.

The production vehicle crankshafts are cast but very strong, some HD models that were used in commercial equipment, came with forged cranks, ideal for offset grinding for more stroke and a ridiculous piston speed.

How do these specifications compare to the 4.0?

In stock efi form, they only made 145 HP but they did generate 265/270 TQ down low , won't get anywhere too fast but it'll towing with the big ci engines.

I appreciate everyones thoughts, if anyone happens to have pictures of someones jeep with one of these powerplants, PM or e-mail me, I sure would like to see it.

Thanks

Yeah, in the Arabian peninsula the Ford 4.9 I6 is about as common as hen's teeth.

Looks like your doing ok with variations of the 4.0.

Although I find nothing wrong with boosting power, or engine swaps, it amazes me how important many feel it is to to crank out as much hp as possible. I never considered any Jeep product really worthy of a quest for hp.Maybe lowering kits are in order? The design alone, (body) is not something that lends itself to speed or handling.As far as off roading goes, with the right gearing,taking a good line, and driving with your head and not your foot, the 4.0 is fine.Maybe more people should drive 18 wheelers,then they would know what sluggish really feels like!

:bs:

My Jeep not only is surprisingly, fast, light and agile for the type of vehicle it is, but is also the best handling 4x4 I have ever driven. It will cruise at 80 and if you put the pedal down, holds its own against low end mustangs, civics, Focus (Foci?) etc.

I agree there are design limitations to the XJ unibody, and my brakes suck but a stroked 6 would do no harm and be good on and offroad, without bieng overkill.

A stroked ford 6, maybe thats a bit much.

Ah - but I'm not on a quest for horsepower, I'm looking for more ways to squeeze torque out of the engine.

"Torque makes you quick, horsepower makes you fast." I'd rather be quick - comes in handy when taking evasive action in CA traffic. Also when towing, hauling, or when I finally get this thing built to take out off-roading (so the stronger engine will have to come with lift/axles/tyres/brakes and such...)

The XJ isn't designed to go fast (which is part of the motivation behind Project: REDSHIFT, to be perfectly honest - but it's a thoroughly one-off job!) but it IS designed to pull, haul, crawl, or otherwise handle damn near anything. My 88 with 245K is already doing the job well - but I'd like to do it better. Believe me, when I'm considering parts, I'm thinking more along the lines of 1500-4000RPM then what's happening at 5000+ rpm!

Ah ha and thats why I brought up the ford 4.9, its a torque maker.


Stock stroke/rods (300ci) = 400+ TQ with some well placed attention.

If you are not inclined to use the stock ford EFI, that over the valvecover manifold would require a huge hood-scoop...consider a properly sized and set up LP system mounted on a crb style manifold...no off camber fuel problems like a gas carb setup and throttle response should be as good as EFI.

We ran the 4.9 in all of our fleet vehicles as long as they were available. They are EXTREMELY durable...as opposed to the newer 4.2 V-6's...what a real ig: .

 

[junkjeep]

how about an offey intake with a tbi set-up?
