Interesting adaptation

[4cruzin]

I agree!  Looks to be done well from what I can see! 

[Blakcharger440]

Sweet. They did a great job!

nice ride and cheap too

If I want a new motor I get a newer car with it too. The chrylser's 300's are just ok on the street here, maybe with a little more gearing it help, but I rather have the 383 or better yet a 440 in it. Its not sold yet, he might think its worth 30,000 or so. I am sure he put alot of time and money in it, thats why the old motors are better. For the same amount of cash you can get more power out the old motors. True- some places have smog laws and limit what you can do ,so then it be good to have this motor. If it sells thats why, in Nevada they go back to 1967. Here in Michigan no car is ever tested so its a waste of money to put a new  "hemi" in a old car.

[bull]

All the hassles of emissions and computerized sensors with none of the benefits of not having them. No thanks.

[tan top]

intresting swap  , looks a neat  job

[ChargerSG]

Mayby i would stop with my swap and buy this one(but repaint it Black or someting)

Personally, I prefer driving my wife's fuel injected 360, od tranny 73 cuda over my 426 70 challenger convertible. The cuda boils the tires, runs smooth as silk and gets 25 mpg on 87 octane. The challenger really boils the tires, runs a little rough while idling at lights and gets 8 mpg on a good day on 93 octane.
In fact, none of my big block cars get over 10 mpg. Needless to say, they're not getting a lot of drive time right now. We're driving our small block cars a lot more right now since gas hit 3.05 for regular.

I like it. It would be interesting to see the numbers on this combo, ie:  mileage, 1/4 mile, 0-60, etc  and compare it to a stock 383 or 440 car.  Fuel injection is the way to go. IMHO 

[dodge freak]

Why a stock 383 or 440. This is 2006 not 1970, we have so much great stuff out there now for engines why not use it ? Anybody who is running a car with 35 year old stuff is going to think these new motors are great. If fuel injection is so great why do the racing cars still use carbs. ?

[Blown70]

Sorry I think of HEMI and I think of a NICE FAT valve cover.  While I do appreciate the work that was done.  When you say it has a HEMI, at least look like a hemi.....

[BigBlackDodge]

Because it's easier for the officials to regulate and spot the cheaters.


If I could afford a swap like that I'd do it............much more reliable...........much more efficient

Your missing the point df......If in fact this is a stock 2006 Hemi engine/trans combo, I would be curious to see how it stacks up against our beloved 383/440 engine/trans combo in a B-Body.

When holley and  other carb makers sell more EFI units than carbs they may push for the pro racers to get the change they have been after. Till then its "old school" .

And yes you missed the point I think.

[dodge freak]

The point is for the same amount of cash maybe less you can build a 383 with Eddy heads , roller rocker arms , headers, MSD ignition and a holley hp carb. That motor will have more power than a new "hemi". Sure the new "hemi" will get better milage but unless you will be driving it a 100 miles everyday big deal. It would make a lot more sense to just get a 1 year old Chrylser 300 with a warranty to go with it. We have not even seen this, just hear it runs as good as a SUV, well thats not so hot in my book. I like to know how he did the speedometer also and if it reads right. Fuel injection cost way more than any carb. and a carb thats tuned right will idle good hot and cold . Mine does so I know first hand.

The point I am making is if you want a new motor get a new car, it have a warranty.

What I like to see is a new car with a hot old motor in it, but the frame won't hold up unless you change that too.

[Lowprofile]

 

Ah, Tomorrow is another Day. 

[dodge freak]

Go down to a drag strip sometime and see "real" fast cars and then look if its a carb or F I , maybe it can be done but why? These carbs. are still great after all these years.

Another problem with F I is that to get a racing motor to have max power at 7000-8000 rpms you need a hugh injector. No problem but then at low speeds 2000 rpms its too big and will run rich. I think the answer is 2 injectors for each one, at low speed one injector is working at high speeds they both are, thats how these $300,000 sports cars do it but if there is no emissions to worry about why again. I do think there are 10,000+ rpms  F I racing motors out there ,mostly overseas but those cars cost over 1 million dollars to build.

These top fuel cars that run 300 mph in the quarter mile burn gallons of gas in 6 seconds, a fuel injector can't spray that much fuel, you need multi-ones. This is getting off subject-sorry, lets see how much that car gets bid up too.

[dodge freak]

Wow just did a google check on top fuel motor they ARE fuel injector motors . 42 of them, some on top of the supercharger , some in the manifold and 2 more by the spark plugs. Those motors burn 10-12 gallons of fuel during the warm up and quarter mile run. The engines are the old style "hemi" and are 500ci and make 6000 HP. Wow again.

[694spdRT]

FWIW most of the people doing these conversions are not trying to be the fastest guy around. There is always going to be someone "faster" and lets face the fact it will probably be something newer than our old Mopars anyway. I think these conversions are great for people that want to drive an older car with all the modern convenience of fuel injected powerplants, overdrive trannies, A/C, etc.  I am not that old but I am to a point in life where I wouldn't mind hopping my old car for a 1000 mile worry free weekend cruise and get 25mpg. Plus, I don't drag race so having another 100 or 200hp is pretty pointless for me.

It probably will cost more for this kind of setup but you can get real low mileage complete dropout 5.7 Hemis for $2K and for about $3K more in harnesses, oil pan, mounts, fuel pump, etc. have a running engine in an older car. I would seriously consider doing this if I could get my 833OD to bolt up properly. I just got the 5.7 Hemi installation DVD and catalog from Hotrod Lane in the mail so I have been checking this idea out recently.

 

[dodge freak]

Well in a few more years those motors will be all over the place and the prices will go way down. Don't understand why the old motors aren't good for 1000 mile trips, with a MSD box and other new stuff it be just fine-won't get 25 miles to the gallon I will agree with that. I drive my car about 3000 mile each year and a few years ago when gas was half the price 5000 miles and its been running just fine. I did change just about everything, carb. ignition , wiring to the motor , hoses , belts etc. You are 10 years younger than me so you have lots of time, Good Luck hope it works out for you.

[694spdRT]

I agree an older engine can make it 1000 miles if it is sound. We took a 383 Super Bee on the HotRod power tour for nearly 1,000 miles two years ago. Other than a broken throttle cable we made it fine and got 12mpg with 3.23 gearing.

I have 2 cars with big blocks right now so now I need to decide between a "been there, done that" 440 for the Challenger or something a little different and more usable like the 5.7 Hemi. I do like how the 5.7 Hemi's run even if it is not a "real" Hemi so that is why it interests me.

As for the price of a newer Hemi I wouldn't expect it to drop much for low mileage ones with all the accessories and computer. I called around for a dropout 360 Magnum thinking that they are getting older now so the price should be reasonable. The best price for a worthwhile one was within $500 of the 5.7 Hemi and it had 50,000 more miles.   

[Silver R/T]

I dont think I would have to pass emissions on it, its a 30 year old car and I would get collectors plates on it and drive it pretty much anywhere with new dependable engine. It gets better mileage than big blocks too

I guess I should have specified pro stock and nascar + the nitro and supercharger has a fair amount to do with the insane hp.

[dodge freak]

I thought he meant the motor has them and if you take them off the motor will not run right even if the cats. are removed the back pressure will change and may cause a lean air-fuel ratio.

Look its still a 36 year old car-what about the brakes, springs, steering, wiring, lights all that stuff can still break down. I look at that ad again, sounds like the speedometer is not working but some place can get it going. Yeah-right for what a $1000 , and that 25 miles per gallon is when half the motor is turn off, which all those sensors are for, thats very tricky to set up right and not cause problems like the motor-car shaking, the trucks do not have it yet.

I think for anybody who wants fuel injection they are better off getting the edlbrock unit for $2,500 and a gear vendors overdrive unit to go behind a 727 trans. The edlbrock is user friendly-easy to adjust, not like that factory hemi, it get much better milage and run great too. The 360 and even 318's are great little motors and will get good milage with that fuel injection. Wait until the aftermarket gets a kit out to swap these new hemi's, otherwise it may turn in to more work than fun.

Another problem with F I is that to get a racing motor to have max power at 7000-8000 rpms you need a hugh injector. No problem but then at low speeds 2000 rpms its too big and will run rich. I think the answer is 2 injectors for each one, at low speed one injector is working at high speeds they both are, thats how these $300,000 sports cars do it but if there is no emissions to worry about why again.

A fuel injector is regulated by computer so they dont run rich/lean

[dodge freak]

If the injector is too big it won't run right at low speeds. Look at the aftermarket fuel injectors for the Chevy motors, they have 3-4 different ones, the bigger ones are for hotter motors that need more fuel, if you put too big of a injector on it will spray too much gas, there is a limit on how slow the gas can come out and still be a nice strong spray. You just can not put any injector on and think the computer will lean or richen it up. They are just like carbs. one size does not fit all.

YOU MEAN TO SAY IF YOU SET THE COMPUTER CORRECTLY.....

[694spdRT]

According to Street and Performance (aka Hotrod Lane) you don't need to run cats for it to run properly. Just need the oxygen sensors hooked up in the exhaust. The way it sounded in the video some of the other emissions items could be by-passed on the cars they were building. I do agree that if you are not going to update or restore the rest of the 30+ year old parts on a car having a modern engine will not get you much more reliability.

BTW: In the video the new automatic trannies in the Hemi 300's and Charger's are actually quite small and look to be a much easier swap in older cars than the previous A518's or Hemi truck trannies.

[dodge freak]

I think those are 5 speeds too.

[Ghoste]

One of the 66 Chargers used in the movie Big Fish was purchased by a school in the Detroit area and they put a 5.7 in it.  I don't know if they have any performance data on it yet but they have been showing the car all over the place.  It fits in there pretty neatly.

[dodge freak]

last bid was $16,555 or so. His resever was not met and he never said what it was. Well now he has a 1970 charger with a $5000+ motor and can not sell it. Yes things are not selling to good right now but somethings still are. I am sure if it had a # not maching 440 6 pack it would have hit $20,000 if not more. The motor might have cost about the same, take a $3000 used but great shape 440 and get a $2000 6 pack set up. Would not get 25 miles per gallon but it be worth more on the open market.

[694spdRT]

I think that auction was not advertised very well. It seems worded as more of a "here is a 5.7 Hemi and by the way we put it in an old Charger or something". Little detailed info was given on the condition of the car and it was a green 383 car to begin with which usually brings less $$$.  The install looked to be incomplete too as the gauges, A/C unit, etc. were not finished and that never helps. Noticed they didn't even bother to vacuum it out either.

In this car I agree that a 440 Six pack setup probably would get more value on the open market. IMO it still would not be any better for an all around cruiser and that is what I want in my next car. I don't want a car to sell anyway....I want it to drive.
