Doubt it.

 

The v6's don't get much better gas mieage than the V8's. As far as 6 cylinder engines are concerned, the Magnum 3.9l is one of the worst out there if you care about mileage.

 

I just bought a dakota sport v6 a few days ago. (winter beater!) But if you wanted to get more power out of the little 6 without going through the hassle of doing a V8 swap, I would personally install a turbo.(WAY cheaper!)Heck if I have some spare time and a little extra moey for tubing/hoses I'll install my new garett turbo on this little thing for ****s and giggles just to see what it could do. And if you just want a little extra power without spending barely any money, install a V8 throttle body. (have to have V8 throttle cable also!)(make sure you bore the intakes TB port to match the V8 sizeor it's almost pointless!) I also think hughes engines makes cams for these V6's. I was going to install my 400hp+ 5.9 in my V6 dakota but I personally think it's a waste of $$$! Cheaper to buy a dakota r/t and then do the swap....

 

i bought a 92 dak and yanked what was left of the v6 out, and i stuffed in a 3 spd. 727 torqueflight, with a 318 attached to it.....and did i mention they were out of a 68 plymouth fury, lol. i also have a 03 dakota 3.9 5spd. 4x4 bets mileage i ever got was 20mpg on the highway with 245 70r16 tires, it now has 265 75r16s an i get 14 mpg. as far as the v-8 throttle body it works, but drill the holes in your tps so u can get the throttle response up, and as far as boring holes in your intake, not sure what that guy drives, but my intake has about a 3" by 4" rectangular hole the TB sits on, so there was no borin required, and i used the same ole v6 throttle cable, snapped right on, u do have to change the bracket that holds the cable, 3 10mm head bolts. but a v8 is the way to go, hands down. good luck

 

I have a 98 magnum 3.9 and I get around 300 miles to a tank

 

I have a lifted F-250 with a V-10 and I get almost 400 miles per tank.

 

I have a buick grandnational that runs 9's in the quarter mile, come check out some of our sites, we can definitely get you going in the right direction. looking into a single cab short bed. I already have the drivetrain, just looking for a donor truck.

 

Your comparison is mute as fuel tank sizes vary.

 

Good job digging up an ancient thread just to state the obvious, and help make my point for me.

 

The correct term is "moot". Mute means you can't talk.
