New plans, new attitude...

Ok to everyone that I po'ed and aggrivated to the extreme I APOLOGIZE any tech help or advise would be helpful. Ok I was planning on doing a V8 swap but have decided to switch from a 3.0 to 4.0 stroked to 4.3 liter V6 because it has the engine stickers in there (2.8, 3.0, 4.0) and belt pattern in there. I figured I can still retain the value of my ranger plus hopefully U guys can tell me wether or not I have to switch mounts because I am unsure of this. The air intake system is going to be kustom built by me. and what type of throttle bodies would U recomend? the headers are stock, and I am keeping my muffler on there as well. The muffler is NOT stock. And I am sorry for acting like an ***. hey Dayno J. forget what I said, i am sorry hopefully U guys forgive me and forget anything I said.

If you are using the stock block.....no mount changes should need to happen. STOCK block = STOCK mounting locations. Figured you'd know that.....and i'm not an engine builder. Headers are not stock, they are cast manifolds.


On a side note...thanks for coming back with a different attitude. I;m sure many members appreciate it.

Ok thanks. I figured U might have to switch the mounts but wasn't sure. Sometimes u do, sometimes U don't. well U know. Oh the Tornado exp. has ended. U guys are right I just didn't catch it. They snuck in there with a unichip. The Tornado is JUNK. I am glad U guys don't hold any ill will towards me. Thanks man. Here come the hard part. Finding a stroker kit for a 4.0 V6.

Thinking about compression and what kind of pistons to use. Kieth Black performance pistons would be sweet, but unfortunately they are extremely high dollar.

hey my spell checker was broken but it is fixed now. Things are going ok for now, still doing research on a stroker kit for it, and I am looking into supercharger as well. I'll keep U guys posted as much as possible. I did call Kieth Black Performance to get a price quote on some pistons, It wasn't pretty to say the least. Just for the pistons, rings and 3D H-Beam rods was $3,654.21. In other words Too much money for what little U get. I should call Eagle Performance for this because at that price I can get a freshly built 302 from summit at that price. I guess I just better pull out the old resource/street rodder magazine and see what I can find in there. Thanks 04Edge. I glad U didn't hold anything against me. hey what kind of compression do U think I should use?

Ok, now we are getting somewhere...

I found a new roller rocker company. They're Called Scorpion Performance. I haven't contacted them yet but I am hoping that they'll have what I am looking for. Crane Cams wins. They have alot of profiles to choose from and I have decided to use a carb instead of fuel injection, but it will be alot of work involved. What would be the best thing to do in switching from Fuel Injection to a carb? Hey Dayno Jaye, please feel free to jump in here please. If u have any input at all on this would be extremely helpfull. Thanks. I am going to use 10.5:1 compression ratio. Also I am having trouble finding a rotating assembly too please help? Thanks to all that can.

Why would you ever go from EFI to a carb?

Read this article:

http://www.carcraft.com/techarticles...efi/index.html


If you are going to use this truck as a daily driver, I wouldn't go with a compression ratio that high, you will probably have trouble with 93 octane, which will be hard on your wallet too!

Hi Takeda,
To answer ur question mine is also going to be converted to "Flex Fuel". That is the reason for the higher compression, plus if U advance the timing u can run 87 octane. As far as the carb goes more power at a cheaper price, but as of today the carb is out. I would have to "rewire" the whole damn truck and if it aint broke don't fix it if u know what I mean. So that notion is out of the question. Too much work. and Mine is TBI not EFI which is strange to me. Plus it looks bad for swap bcause I can't find what I am looking for the swap is on hold till I do. Plus if u look at the pump in the morning u'll be shocked. Gas here in VA just went from $2.89 per gallon to $3.20 a gallon for 87 octane! Overnite basicly so don't be surprised. They screwed us yet again. Damn it. We need to get George J.R. out of there.

Swap on hold...

Well ladies and gentlemen, the swap is on hold. I can't find the parts that I'm looking for. The Carb notion is out of the question. I would have to rewire the whole damn truck which is no good. If it aint broke don't fix it. Plus alot more is going to be needed to convert to Flex Fuel. If u don't why this option popped up all of a sudden take a look at ur gas pump in the morning. It's up and down more than a toilet seat. If it gets any higher we'll need a ladder to read the friggin prices. Damn it man.

I thank u for ur input man. it is highly appreciated. Carbs or EFI has always been at a dispute. For racing, Carb without question. Daily driving EFI no questions on that either. But some carbs are for daily driving (O.E.M only). usually it causes drivability problems, but on the other hand, I've seen some sick a$$ fuel injection systems that are worse than a 1,000 cfm carb too. I guess it really depends on ur taste and ur application.

First, the timing will have to be retarded to run 87 octane, NOT advanced!
And with 10.5:1 CR, to run 87 octane without pinging, you will have to retard the timing to the point it won't have enough power to get out of it's own way!

I hate to tell you, but your ideas are total BS, just like your tornado!!!

Ok easy now takeda. The tornado is gone. And that is not what chevy performance mag said either. in Feb. of 08 issue dude. U only retard the timing for superchargers, and turbos. plus u didn't hear the words flex fuel either. Go to this site and see the octane level urself if U don't believe me. www.e85machines.com . I may not have to bother with the timing. it is rated at about 116 octane.

here's another little fact. They do have conversion kits for E85. for the ford ranger. and the tornado scam was found out when I attempted to put in a new cpu program into my truck. They already tuned it with a superchips program. And I thought that damn thing actually worked. Shame on me. and if U ask me My idea are not B.S.

NOT TRUE! You RETARD the timing with a N/A engine to reduce (or eliminate)pinging from high compression!!

Are you even aware of the differences between a FFV and NON-FFV vehicle?

Yes I am aware of an FFV and Non FFV. Ethanol and gasoline mixture. I said and I quote: An FFV conversion kits are available. But I didn't exactly say that I was going to purchase their kit did I. I'm talikng about a possible swap with what I have,only the FFV version of the engine. They did make an FFV 3.0 V6 and a 4.0 V6 in the Ranger. What years I couldn't tell U exactly, but i am pretty sure in the 2005 model year. Go to www.fordvehicles.com and see what FFV engines are available. The timing issue though is behind us. maybe ur right and i'm wrong or i'm right ur wrong, and for all we know we both could be right and, or wrong. it really depends on the type of engine ur running. For racing i am right. For street I am wrong. I just read that article a few minutes ago and these guys are running the "happy Juice". here's what they've got listed: Displacement= 4.06.0 Bore x Stroke= 4.155 x 3.750 Pistons= Probe Forged heads= Dart Pro 1 CNC, Compression= 11.1:1, Intake Manifold= Edlebrock Victor J.R. poert-matched, carb= 850 Mighty Demon 79/87 jets, Camshaft= Comp Cams Hydraulic Roller Valve lift= 0.600/0.619 (with 1.6 rockers) Duration= 248/254 degrees (at 0.050), lobe seperation= 110 degrees. Ignition= MSD 7AL Digital, Headers= Hedman 1 3/4 inch long tube, 18 inch exstensions. Baseline (DYNO DETAILS) Fuel 91 octane, ADVANCE 36 Degrees, Peak hp 594, Peak Torque 539 Average Hp 461, average torque 500 Ft. Lbs. This was from CHEVY HIGH PERFORMNCE MAGAZINE. The article was called UPPER LIMITS. U'll find it in the Febuary 08 issue. So tell me takeda, with no nos spray, 91 octane in a 11.1:1 compression ratio 406 C.I.D engine, ur saying that 10.5:1 is too high on a street vehicle?! This engine was and is STREET LEGAL. U just don't know too much about compression ratios do u.

I'm impressed on your cut & paste abilities, but it's so sad you don't understand ignition timing, and it's affect on pre-ignition!!

Why are you stopping at 10.5:1 CR why not go all the way to 11.1:1 ??

When you say STREET LEGAL, does that mean it passes all the emission standards?

Keep on dreaming!!!!!

B4 u get even wound up even more, do u even know how high u can go with compression ratio b4 U go to the 93 octane? here's the answer 10.0:0 Dodge Vipers, Ford SVT 10 cylinders, The new Shelby Mustangs, are all running on 9.0:1 compression, aka mid grade or higher. it says that in the service manuals as well as on the dealer sticker too. So b4 u say someone is B.S., be sure not to stick ur foot in ur mouth just like u just did. I don't think CHEVY HIGH PERFORMANCE, MOPAR ACTION, FAST FORDS AND MUSTANGS and other respectful magazines would print that if it wasn't true. It is also located in the owners manual as well.

Plus I was also thinking of usuing that compression. Didn't say I was. and yes it was street legal. I guess other in here who have the happy juice and high commpression ratios are also dreamin right?

No, only the ones like yourself that doesn't have any technical expertice at all!!

Let me help you with the timing issue! In engines with a "knock" sensor, that is used to detect pre-ignition, the PCM will RETARD the timing when pre-ignition is detected, the timing is NOT ADVANCED!!!!

And b4 it goes any further, Takeda. I didn't mention emissions legal. I'm already under the new grandfather clause (thank god) bcause if they were to do an emissions test right now on my truck, it would fail in a heartbeat that is for sure. But ignition timing was an issue I had to address. I wasn't sure so be but as far as b.s. goes, I wasn't B.S.ing.

NO TECH EXP?! excuse me pal but I do Have tech EXP. Quite a bit actually. I may be confused about the timing issue i agree, but as far as U saying that I have no tech exp. WRONG.

I'm sure you are a legend in your own mind!!!!!

Confused? NAH....you just don't understand basic internal combustion engine principles!!!!!!

Hopefully you will be able to understand the chart in this article on page 4!! This is about as basic of an atricle that I could fine!!!!

Basic timing and comression ratios is simple expertise. If you have technical experience you would know this stuff man. Converting to a carb requires the whole truck to be rewired???? Why??? Man, just be honest so you don't sound like a fool. Then we will help you. BTW, good luck with E85 and a carb.

Now, be easy on him, he gets confused so easily!!!!!!


But, then again, you have to wonder about somebody that would fall for the Tornado claims!!!!
