Hmm...sounds expensive, and hard to get. Guess I'll have to rethink that one.

 

what would be really cool for someone to do is take 2 300 I-6s and mate them together to make a 600 V-12. Let's go by the fuel-injected power rating of 145hp and multiply by 6 since you have 6 more cylinders suplying power to the other 6 cylinders in one crankshaft, so you will have 870 hp. Let's do that to the torque figure of 265ft/lbs and you will have 1590 ft/lbs of torque. And how about a twin turbo setup? With 10lbs of boost from each turbo, i would say about 1000hp and 2000ft/lbs. Now lets convert it from gas to Direct inject Diesel and stuff it into a F-450 with a 13spd and a military rear axle and we will have the best Ford truck built that can't be beat.

Only if my over rated imagination came true...

 

I have a question. Why is it so important to have a mass air meter for a turbo setup or even a blower? They make centrifugal supercharger kits for '87-'96 trucks with 302's and 351's. 90% of those trucks have speed-density EFI. There are also a lot more cars out there with no mass air and boost. Is it just a matter of how fast the computer makes adjustments with a mass air meter? With a reprogrammed computer, I don't see what the problem is.

 

This thread got totally hijacked by folks who beleive it's reasonable to get 500 HP out of a 300. I bought a truck with a 300 because they get great milage with legendary reliability after my '77 V8 street rod got stolen. I've heard a lot of theoretical discussions about performance, which is always cool, but not one person has known to gone above 350 HP, nomatter how much boost you use. Actually, that guy claimed his brother's best friend's cousin's barber's second brother in-law got 700 HP and 900 TQ to the ground, which is of course a lie, an exaggeration, or both.

If you want 300 HP, and reliability is a factor, then buy a V8.

Seriously, there are V8's running around now that make almost 400 HP and get nearly 30 MPG (Corvettes), and many 300 HP V8's get over 20 MPG. In a truck, you can still do 300 HP and get 17 MPG (I've done it, and carbureted too!). Watch the Pro 5.0 guys, they're spending as much money as the 500 HP buildup people, except that they're making over 1,000 HP and running 6 second, wheels-up quarter miles.

300's are very cool, I love mine with a passion. It beats up job sites every day with 2WD, only gets stuck when I drive it into uncoverd manholes (OWN3D!!!), and still scores 16-17 MPG. When I want my weekend power fix, there's going to be a '68 F-100 in a deep, dark corner of my garage with a 351W-based stroker that will destroy pavement. If you shoot to make over 200 HP out of your I-6, then you will lose everything about it that makes it so great.

Turbos sound great in a "Junkyard Wars" kinda way, but for the rest of us who need a ride to work, and occasionally haul some tools, keep it just the way it came.

 

we have many corvettes {with the rite parts } at 400 to 410 hp
at the wheels that get 27 to 32 mpg if not beat on.
I have way too much $$$$$$ in my truck to say my power is
reasonable, but i posted way back that my 300 turbo was/is a
test bed for my real toy .

 

If a person wants to hope up a 4.9 300, I say go for it....everyone and their grandmother has a v-8.

I can't forsee a reason why the 300 is incapable of make reliable hp and tq, above stock expectations.

Two things missing when it comes to the six, one, not much of anything as far as aftermarket or factory aftermarket (svt if you will) support. Two, average joes like myself who do make attempts, don't seem to follow through once a problem occurs, which is expected, life happens and other priorities occur...so how can anyone come to a definitive conclusion?

I am confident the six is capable, ignorance is bliss, right? Not to mention, look at what has been done in austrailia were the inline was approached differently....very impressive.


Here is a spin on logic, if your in the v-8 sections, your guranteed a comment, trucks need torque ~ build for tq let the hp fall where it may...makes sense right? In the inline section your guaranteed a comment, you'll never make hp with the six, go with an eight, the six is only good for low end tq. Okay.......???......


....we live in a world (luckily) were family sedans are making right at or more than, 400 hp and equal tq, with a service life of well over 100,000+ miles. It would be a fair comment to say building any pushrod engine would be a waste with the technology available today......but the way I see it, who cares, do what makes you happy.....let everyone else worry about themselves....no matter what a person does, someone has done it better....if your fast, someone is faster.....

 

I don't see any reason why a 300 can't make any good hp and torque if you build it right the first time. Remember that 300s were a reliable motor that was in production for 31 years. In my opinion, I think it provided the best of all worlds in what a 6 cylinder can do. It produced fairly good hp, stump pulling V8 tq, and pretty good gas mileage for its displacement. my truck averages between 18-22mpg or about 320-360 miles per tank full, which is pretty good since it has almost 127,000 miles on it, and i only use one of my 2 tanks. with 2.73 gears and a 5-speed, i have pulled anything from broncos to F-250s. 300s should be brought back.

Hey where u sitting at now? Do you have your truck going again? Plus can you give a description of all you have done. Im about to tear into mine and put a turbo on it.

 

still wating for a custom headgasket

 

*6? I do believe adding 6 more cylenders would only double the HP, HMMMMM!. You would be closer to a 300 HP INLINE 12.

its no double 300 but it is a 600ci v12.

i think eriks250 was being sarcastic

Here is some useless information:


Using the ea engine analyzer, I set up a combo that would mimic the stock efi peak numbers at the crank. Then added a medium turbo producing 7 psi boost, the peak numbers of the boosted I-6 were real close to your rear wheel numbers, to make it a little more interesting your average hp is 143 and tq 287 and the simulation program I used shows avg hp to be 186 (wouldn't that be nice) and tq 284 real close to yours. The heads and camshaft are all wrong on this program, they were as close as I could get them but they did mimic your numbers to some degree, even if yours were at the rear wheel.

Something else, I punched in a 351w with ported heads, performer intake, 600cfm carb, and XE256H-10 camshaft, long tube headers....

peak tq 338
avg tq 292
peak hp 296
avg hp 211

Then I took the previously mentioned I-6 and upped the psi to 10....

peak tq 429
avg tq 273
peak hp 241
avg hp 169


Just looking at the avg it appears the v-8 has the I-6 until you consider a few things, the I-6 has the v-8 up until 3750 rpm, of which at one point it betters the v-8 by 125tq and 50hp....so for a street machine, the I-6 would really be impressive....port the I-6 head and use a camshaft to give it some more rpm and who knows.....


What does all this mean....not one darn thing but I found it interesting...thought I would post it up...


later
