I think that's where most of them come from, created from cutting and splicing up other high performance heads and welding them together. If I only had the tools, money, and know-how, I'd start a business. =P

 

Same here. But I'd move in a slightly different direction. The direction I'd go would prolly lead to needing a lot more stuff though, cause I'd be looking to bump compression over the 16:1 range, and swapping spark plugs for injectors/glow plugs.......
Might wind up having to totally re-engineer the whole dern thing, but I think a 4.9L I6 diesel would be a monster worth the effort.

 

That 250-300 HP is possible as evident from that other thread, but something is to be said for using the right tool for the job. If you want to herd cattle you don't use a bird dog. I don't know if the rumor is true, but I believe I heard it here years ago that Ford obtained the 300 from Case. I never did any research to confirm that, but an older Ford mechanic said he had heard the same thing when I asked him about it. If Case did sell this engine to Ford it would explain it's character. Like others have suggested, if this engine was a horse it would be a Clydesdale. (Think Budweiser Wagon). Now can you train a draft horse to race, maybe. But without a lot of effort. It might be easier to go get a race horse. This won't work on your year engine, but a friend upgraded the original 12-lb/hr injectors on his 4.9L, 93 F150 with a real injector 19lb/hr. I think He had to place a fuel regulator to drop the gas line pressure, but what an improvement! It was never on any dyno, but you could certainly feel the difference and still used regular gas. I believe he learned how to do it on this forum.

But ya gotta give it drugs n that aint right in my book (i know Percherons pretty good, nother gentile giant).

My belief is just as researched a yourn, 300 evolved from an attempt to "stem the tide" of the volkswagon bug's invasion of the american auto industry (think jap invasion, only earlier - ie your annalogy: "think Budwiser"). The "falcon" motor (small six) evolved from there (a 144 ci) to mustang and onto an adaptation to truck (240 I6, the big six), got 'stroked' into the 300 n was injected @ the end game. 'Cept Austriala kept goin to the X-flow (250 ci = 500 hp) an engine in the 7th generation currently Down Under. I got a 250 I6 comin from TN (2 Mass) that's rated 240 tq @ 1600 rpm stock in 1969, just bout right 4 my application. Which is what it's all about, application.

Take a 300 n turbo-ize it, it'll 'get U there' but that aint my application.
PS: I like your thinking!

(Sorry) Blah, blah, blah (right?).

 

I would be game to test it but gas is cheaper these days but ya it's just a gas fired deisel and if there is a will there is a way as has been proven

few pages back is a vid of a maverick with a turbo pull'n the front tires off the ground and run'n 11's on the track


for me and my needs in my 4x4 I dont need that lol as all the work is done at low RPM and I didn't lose that with my upgrades, just made things better a bit torque wise. but I can see now that I have more HP then I can use off road(my main use) but dang can I get on the freeway at 75 in a hot sec now if need be for more gas

sure it would do the same converted to diesel as well with the know how and a turbo.


OP sorry if I missed it but, what do you want your 300 for?

 

Hey, Andre'
(sun just set here)

 

Heck, they've been working on one for nearly ten years now, and I've seen nothing.
What do you suppose the chances of it being less than a grand IF it ever makes it to market?

 

Mo' money.

The gas diesel was tried in the 80's (I think it wuz 87? 83?) when chebby converted the V8. Just kept blowin up, bud 'od get a new engine every few months for free.

 

I totally love how your motor turned out. If possible, I want to do a similar build on mine.

I just can't help but think the 300 (or even 240) would make an excellent starting point for a utility diesel. It may not be a power monster, or be capable of winding over 3000-3500 RPM, but man would it make some awesome torque. I know gasoline is cheaper per gallon, but diesel tends to be much cheaper in the long run. Case in point, I had an 80 VW Dasher wagon with the 1.5L diesel, and it got 35-40 MPG. Same car, with the 1.6L gas engine would get 20-25 tops. Granted, the gasser would run off and hide from the diesel, but tie on a 1000LB trailer, and the gasser would barely pull itself, yet the diesel pulled like it wasn't even there. Stopping was a totally different story, though.
I would tend to think that 4-5L I6 diesel, with a small turbo, could be capable of producing well over 300 LB/FT of torque, and still acheive 35+ MPG in a full size pickup. Might be a pipe dream, but it could also be a wet dream.......

 

Seems like a Paxton or Vortech supercharger would be much easier than rigging up a turbo. I'd like to build up an old three window coupe with a blown 300, something to really embarrass the jackasses that drop SBCs in old Fords...

 

LMAO.... I love you guys down here in the inline forum haven't even posted in the '86 4x4 one yet on my mod's


ordered the chebby intake rocker conversion for mine to today and will play with that after fall


top of the day all

 

Here is THE only aftermarket head for the 300. It is drag race only and it is very expensive!

AJPE



I think I am getting at least 250 HP with my turbo intercooler 300 in my truck. I would compare its acceleration to a 6.0L Powerstroke, all low to midrange torque. I have a DIY ported carb head with oversize stainless valves and Harland Sharp roller rockers actuated by a Crane 284 duration cam. The cam is what I would change to get a better running engine I think. Lobe separation not right, but the engine is powerful nonetheless.

 

I spent just over $3000 on my engine. And it runs way harder then stock.
Maybe quite not 250hp but close. I hit 4000 rpms the other day and was still pulling. It is not like I do that everyday so why pay for all this superdupper stuff inside that no one sees, just so you can say you have it. do you really need ARP bolts for 3000 rpms max? theres a hundred bucks or so. All I am saying is do some research in the classifieds, swap meets, ebay and even yard sells. I bought the 390 forged pistons the rings from a yard sell for $50 bucks. I got A mallory distributor and harland sharp roller rockers from a swapmeet brand new for $175, thats a huge savings. build your own stuff. you dont have to build a motor out of a summit or clifford magizine at their cost.

 

...he gasser would run off and hide from the diesel...diesel, with a small turbo, could be capable of producing well over 300 LB/FT of torque, and still acheive 35+ MPG in a full size pickup

finger poke over to the diesel forums/sites and see what they do with a chip upgrade - impressive. Was it 1.2L that did 7 sec 1/4 mi or something?
These motors don't last long I'd assume (Designed/built for tq; modded into speed) the same story I all ways tout, application, application, application.

 

I agree with you . I love the 300, but unless you really want to dare to be different a 351 or 460 can make much more power cheaper. And even a built 300 would probably struggle to keep up with a good running stock 460.

Just my .02
