Re: Increased MPG for carbs?
How much driving would you have to do to save enough gas money to pay for the swap?
I'm all about saving gas, but spending $5000 or so to swap will take a long time to pay off. Thats like the hybrids, I didn't understand why people were going out and spending $20-30k on a car to save gas money???

I look at it this way....Have more power, Better drivability, OBD II dianostics & I havnt done anything to it other than maintenance (oil changes, trans service) in 8 years....Its an overall improvement, Fuel milage was just a bonus. My 350 was getting worn out, With dual smog pumps it was a nightmare to work on & I still had to smog test at the time. The old Burb doesnt owe me anything, I dont see how in the world me doing an engine swap is in the same league as buying an expensive hybrid $hit box?? |

Re: Increased MPG for carbs?
I'm going to start looking for an s10 T-5 to swap in for milage.
It will drop my cruise rpm by about 1000rpms. That should make a difference!

25-30% gain in fuel economy is what most will experience. That's an easy 3-4 mpg in your case and would put you right at what most brand new SUV's are getting nowadays,,,,not too shabby Almost makes these new fuel injection engines not appear as efficient as they are believed to be..sure does make you wonder. |

Re: Increased MPG for carbs?
It's really fun reading through all these suggestions guys. Especially since I have no idea what I'm doing. And the only reason why I was considering the $8k 383 was that it would be brand new out of the box, dolled up how I wanted it to be, had about the performance I wanted, and got 20 mpg. However, I've decided to just save up for a motor swap (still debating on which) and keep this thing brute. If I get better mileage, so be it, but I want this thing to be a terror, instead of a Prius (which, looking back at the op, was how it sounded to me lol).
Does anyone know how much mpg the Hennessey builds get? I'm not saying I'm considering them since they're WAYYY out of budget, but I'm curious as to what high powered cars get mpg-wise. And the sole reason why I'm somewhat bailing on the idea of getting in the 20's for mpg is that I plan on buying another car and have that be the mpg-getter while also being a track car with all the amenities inside. But I'd still like to hear what I could do for performance that'll also increase mpgs for my truck, i.e. what cams, lifters, headers, rear ends, etc.

Re: Increased MPG for carbs?
I have been renting cars for trips to phoenix from Tucson for the past year. I find that the Japanese and Korean small cars consistently get 43 mpg with about 50 miles of city driving. Actual mpg on hybrids is not much better, so why would anyone spend the extra money for one? BTW, the best mpg I got on GM small cars on these trips was 34 mpg. Honda Civic is the best all around vehicle for economy and comfort, but the Hyundai models are a close second.

Re: Increased MPG for carbs?
Not sure how much good a tonneau cover does , I've seen studies where the volume of air in the box revolves and helps the aerodynamic efficiency of the truck. The mass of air rotates and allows the air travelling over the top of the truck to move over the box with a lot less disruption than you would think.
I think panel gaps and design of the undercarriage are big factors. Looking at my 1991 suburban , it is a un molested truck and panel gaps are all over the place and the amount that they stand off the body is not consistent. Lots of places for the air to grab and create drag. |

Re: Increased MPG for carbs?
Not a full toneau cover. Look at these NASCAR trucks.

Re: Increased MPG for carbs?
hey its the blurple lol
i get 20mpg hiway and to get that i put the fast ez efi and put a nv4500 in my truck. i may be able to get more if i swoped the gears carbs arnt 100% best i can tell you is keep your air filter clean. a little restriction will add more fuel droping your mpgs. a carb will never be best of both worlds if you wont mpgs with a carb your gana have to put the smallest cfm carb on it but there goes your power your gana come to a point where you wont more and it will take money to save money weather it be o/d trans, fues injection, low pro tires, lighter driveline parts
