main concern there is the head. I dont think he can get an EFI head to flow, but he might be able to bolt on a carb head, with EFI intake manifolds, theres an idea.

 

over on fordsix there are a few VERY good threads on head work...albiet its for carb'd engines im sure most will work for the EFI except the areas concerning the actual combustion chamber like u said...plus it has that kick-*** "swirl" design...

 

I detect sarcasm when it comes to the "swirl design" lol. Maybe you can take the swirl outa the head, and use a tornado off a late night infomercial to put it back in the intake!

 

NOW theres an idea!

 

Im aware of what Flashman has done. But .060 over isnt a true 312. Its about 309. The way I am setting it up, the engine won't have any emissions crap to deal with, it will be capable of high (for a 300) HP and TQ, and should get somewhat decent mileage. The plan is to set it up so that I don't break anything internally (or externally for that matter), and to set the computer up in such a way that I will be able to keep a fair amount of power on tap at between 1500 and 4500 RPM. This was my initial idea, to get power through that range. So I began researching. MegaSquirt II is cheap, especially if you buy and build. This truck is going to see about $7000 over the next 2-3 years, and aproxamately another $20,000+ in the following 2-3 years. The engine is actually one of the parts that I am spending the least amount of money on. Mostly because it is not going to stay there forever. Money doesn't matter to me. You make money, you spend money, its part of life. I have what I need, it's time to have what I want. You say that a forged crank is excessive, I say I would rather have something that I know isn't going to fail me. There is no way that I am going to rebuild an engine and not put in new pistons and con-rods. Especially not the stockers after the engine has been bored (lol, can we say excessive blowby). I'm used to working on diesel engines. Matter of fact, the only 3 gas engines I really even care about are the 300, the 351C, and the 400M. I know it is mildly ridiculous to get upset with somebody, but when somebody attempts to insult my intelligence, I get slightly aggitated. I mean sure, everybody has their own agenda, and their own ideas, but apparently I am the only one who has the ability to see somebody else's ideas, hopes, dreams, or aspirations, regardless of what I would do, and say "Yeah, go for it dude." Optikal Illusun, I may just be an ol' country boy, but please, don't insult my intelligence.

 

Also, the reason for such a powerful alternator is because I am going to be running about 6 offroad lights, and some chicken lights, as well as a few fog lamps. Not to mention the higher than normal current draw from the electric fans, and a medium draw from the CB radio and cd player/ speakers, air horn solenoids, PA, and of course, charging the battery.

 

Well bore it out to 312 then, by your math, thats 80 over, have fun making that reliable. If money is no option, dont try to extract power from those extra 3 cubes. Also, if money is no option, why even use megasquirt, its the cheapest form of standalone available, because it lacks alot of features others have (including the use of MAF). Look into haltech if you want a better ECU. You can get stock oversized pistons to 60 over, 80 over though.... Try 60 over and 351 pistons, they fit, but im sure you know this because of your research. THEN YOU CAN GET FORGED FOR HALF THE PRICE OF YOUR CUSTOM ****EEEE. I didnt tell you to keep the old connecting rods, I just said they are forged as is, and will have no trouble holding up as long as you dont rev to 6500, and since you plan on staying under 5K, then that saves you another 800ish $ for your custom Con Rods.

 

let me put it another way, the way ur building this engine is going to possible come back and bite u in the ***. for the reasons topgunjeff mentioned the forged components arent needed. ur not working with a diesel that has 16:1-22:1 compression...the most a 300 will like is 10:1 on premium fuel and i hope u wont be going up to 6,000...it just isnt needed. im around big truck diesels and auto gas engines enough to know overkill isnt always a good thing.

and the 3G swap is a helluva lot cheaper than the powermaster. get a large case 3g from the junkyard and rebuild it urself for a sweet 200A alt for 1/3 the price of the powermaster.

 

NO way optical, Its ALL IN THE AFR, you can run 22:1 on pump gas, 1 word OCTANE-BOOSTER

LOTS OF SARCASM

 

On a serious note though. I dont see this thing ever driving on the street. Your gonna bore those cylinder walls sooooo thin that its gonna take just a little bit of detonation on the dyno to kill it... Back off on the bore PLEASE. Whats the point of going 312? SO you can say youve got the thinnest sidewalls? Or the biggest Inline? For real man, we are looking out for ya.

 

the chinese paper lamp look!

 

I talked to my machinist last week. I told him what I have planned, and he said it was all possible. This guy builds all sorts of engines for all sorts of applications. He's been in the business a long time. Like you guys, he said that .080 was a little iffy, asked me if it had to be at 312. I said I want it to be 312, but if its not possible, then we won't. So I asked him what if we do .060 and mess with the head, could I still pull the #'s i want out of it. He said yeah, we could even increase the stroke a little bit, and get you to 312, no big problems.

 

It doesn't matter as much really, when my next project starts, it will blow this thing out of the water. Optikal, btw, I really hope you dont know German.

 

Why not save your 20K and put it in your next then? Sorry if we came across as @$$es, I am one, at least when I am running on 4 hrs of sleep in 60ish hours. Whats with this magic 312 man seriously? Stroking a stroker to get 312. Your dumping money that could be spent on a 351C at least, if not a 460. All said and done a conversion with a 6spd would be cheaper. and then you get more than 312. Hell bore it out MORE and SLEEVE IT YOU DEISEL HEAD.

 

Well, the idea is to build this truck up as a capable on road and off road truck. Then, I am going to find a 3/4 or 1 ton truck that has been rolled over (no frame damage is the goal there), and drop in a 5.9 Cummins, an NV4500, and a NP241 HD divorced tranny running to Dana 60s front and rear. Then swap over the body, put a lift on it, and have my " Dream Truck ". A Ford with a Cummins. Whats the big deal with 312? Nothing really, just seems like a nice number. Who knows, maybe I'll decide I don't want to wait for the machine shop and do it myself with a die grinder . And I do not want a V8. I'm just not interested in them. I love Torque, thus, I drive an inline.
