I know JVX/Memphis Performance sells an overdrive controller. Jet? Don't know about them. You need some sort of device to activate the overdrive and lock up the converter, if you have a lockup converter tranny. This can be done with a couple 99cent toggle switches, or the aforementioned controller. I gotta check out that Jet site. Oh, and, welcome back to the world of carbs.

toggle switches sound good and what is a aforementioned controller do for me. how and why. and yes carbs are the best thing sinces sliced bread. my grandpa told me a story on how his best buddy bought a new wagon with a big block and it got like 25 mpg. when he took it back in for the first tune up he told the dealer how great the car was for him and the dealer said sh#$ thats wear that carb went. they had put some experimental carb on his car and they had been looking for it. needless to say they took the carb back and he was back to getting 9-10 mpg like every body else. now why can't we have those carbs today were did they go.

and what do you people think of putting the new 518 lokar nostalgic floor shifter in the dakota because i just bought one and i think it will be sweet with this swap i'm doing. 74 dart 318 custom block jucied up, new crossmember and motor mounts to hold it to the frame, 94 518A 4x4 tranny rebuilt, cramed into a 93 4x4 dakota x-cab 3" body lift 31x12.5 x-terrans deep set, with posi rear and front end 3.91

As I understand it, the tranny controller lets you assign functions the way you want them. Overdrive kicks in at preset speed of your choosing, lockup too. Keep overdrive in during kickdown for better passing ratio. It's programmed with DIP switches. Stuff like that. The closest you get to the good carbs is the AFB/AVS line now marketed by Edelbrock. A Mopar magazine recently tuned their new AVS and improved their mileage by, I think it was 66%, and increased power in the process over the old mech. secondary carb they were using (rhymes with Holley Double Pumper). Carbs give an engine character. I mean, Injected engines are great performers, but kinda too perfect in a way. Can't really put it into words.
On mileage, Smokey Yunick has a patented hot vapor engine that was in Hot Rod back in the mid-80's. He had otherwise stock Pontiac Fiero's running 0-60 in 6 seconds, and little 2.2L Omnis breaking into the 5's. These cars got high 40's to the gallon, and passed all projected California emissions through the end of the 80's. Basically, by making full use of the fuel, they were making 1.8hp per cubic inch, but getting great mileage. Did we ever get these? What happened? I only saw that one article, which I still have. Keep in mind it is an officially patented device. He who has the "black" gold, makes the rules.

Basically, you tie a wire into a 12v power source, run it to the toggle switch, then splice it into the middle wire of the overdrive solenoid, which acts as the power source for both lockup and overdrive. That way, you control it instead of the computer. The converter should hold up as long as you're not too radical. Stall speed is roughly 1600-1800rpm on a stocker.

Hey Gen1, do you remember the direct-injected ceramic engine Dodge was working on back in around 93? It was a 1.0 litre, 3cylinder, turbo charged,
2cycle engine making 370HP and they estimated that it would average 40mpg. The pistons, cylinders, and combustion chambers were ceramic coated to take the extreme heat of running fuel mixtures as lean as 25:1. They were trying to get approval from the EPA to give it the smog "Green Light" and the EPA never approved it. Too much NOX emissions. They were supposed to go back and tweak on the fuel/ratio and injector timing and the catalatic convertor and that was the last anyone ever heard of it.

I'm too sure with the 318, but when mix-matching old with new, make sure you get the properly balanced converter for year of the crank, harmonic balancer, etc, etc.
BTW, I resent the Holley bashing. Most people who go to Edlebrock just couldn't figure out how to tune a Holley. Which is actually easy once you've done it and know what each part does. Plus, in REAL racing performance Holley kicks the sh*t out of the others.
I got almost 25 MPG (highway only) on a early 80's Mustang I built. Fairly radical 302, big cam, single plane intake, headers, High comp heads, Holley Double Pump. Sometimes you get freak accidents like that one was for me. Fast as fukk, really drank the gas romping it around but at a steady speed on the highway I could drive it out of town getting over 20 MPG. It was better than the injected engines at the time. Actually, I had that car right when they introduced the 4.6 into the Mustangs. I looked on the window sticker and laughed because I had WAY more power and better highway mileage with my old school engine.
Sorry for the rant and don't anyone get offended. This argument is like Ford vs. Dodge vs. Chevy. No one agrees. It's all opinion. But Holleys can get mileage too. It's probably that most dumb fukks get the wrong power valve, wrong jets, etc etc etc. You gotta fine tune that sh*t.
Let us know how the conversion goes. Just make sure it's all balanced correctly with the mix match parts or you're in trouble.
Oh yeah. An easy way to control the lockup and or OD is to also connect it to some sort of adjustable vacuum switch. When you step on the gas and the vacuum drops, the lockup could dis engage as well as the OD. Use different vacuum switches and other inline controls to fine tune it. I used a 700 R4 Chevy tranny behind a carbed 350. I set the lockup how I wanted. The OD still worked mechanically. I bet it would too on that 518 tranny. You may just have to power up a selenoid so it will be enabled since those only have 3 positions on the shifter with a electrical OD button while the Chevy had 4 positions on the shifter.

Just from my experience...I had a '77 Dodge B-100 Van with 318 2bbl. I installed a Edelbrock SP2P intake manifold with Holley 600/4160 4bbl carb. Headers and no cat duals were already on the stock engine. The intake and 600 gained 1 mpg. A Holley 450 Economaster 4bbl with smaller primaries added another 1mpg and more low end torque. I've seen too many guys over-carb a street engine, and end up with a bucking bronco they hate to drive and then complain about mpg. Pick everybody's brain and use common sense on your combination, and you'll be rolling with a smile on your face. Smokey Yunick was a mechanical genius. He had as good a grip on the workings of the internal combustion engine as anyone in the past 50 years. I always thought Detroit screwed up big time by not using his intellect. If I'm not mistaken, Holley used his input on that little 450. I remember that 2.2 ceramic block Omni. It was so thermal efficient it didn't have a radiator. That was about 20 years ago, but I think I recall Smokey getting over 60mpg in that car on a run between Daytona and Orlando. Again, Detroit: "You Blew It".

Sounds good moparman.
O1Motorsport: FINALLY!!!! Someone else who has actually seen Smokey's work. The setup I read about was the Stage 1, and it incorporated the radiator as part of the homogenizer for the fuel, but the article stated he was working with ceramic components and had developed through Stage 5. This must be what you saw. Seems like they'd post this info on a "How To.." web page since it will probably never be commercially available. That Smokey was a rascal. I read where he was notorious for creative interpretation of NASCAR rules. One rule was that the engine could not be relocated rearwards for better weight distribution. Sooooo, Smokey moved the entire body forward on the frame!!! When they called him on it, he showed them how the motor hadn't been moved in the least. The NASCAR guys were not happy. Drawing sand through the head ports to hide porting marks.....Okay, it was cheating, but brilliant, and a great granddaddy to today's extrudehone process.
I wish Shelby would post a "How to..." on his one-of-a-kind GenI twin-turbo 360-powered Dakota too....just in case you're reading this Shel.

I read an article on Smokey's homogenizer years ago. It said the only downfall was that it was hard to tune and keep in tune, temperature and humidity would throw it off. Kind of like EFI and automotive electronics 20 years ago. If Detroit put todays technology together with Smokey's homogenizer I bet it would work.
Only looser here would be the oil companies. I guess we would see $4.00/gallon gas if a 1/2 ton truck could get 40MPG.
