I bet though if you really spend time with polishing stocker components and used compression and lift to get the HP then you would be more on the track than bigger heads and traditional hp makers. Exact tolerances with piston wall clearance and PTV clearances. dead nutz tuning with EFI...never gonna hear me say that much...just because you can get the variable stuff more effectively.

I couldnt agree with you more:
haa ha well I should hope/think that there must be a way to get 30+ highway with modern tech.

the only way to get good mileage is low rpm's and a lightweight vehicle, it doesn't matter what size the engine is either. i have a 95 dodge with a 488 ci engine and i manage 18 mpg daily driving and 15 mpg towing. my 89 lx coupe has 270 hp and always averages at least 23 mpg highway and 20 city with stock gears. My point is you can get awsome mileage in anything as long as you find a way to keep the revs down.

my77stang

yes, this is exactly what i did with mine [8D]

get the lip ground off the back, then have a seal saver installed and it drops right in. people would never suspect you have a one piece roller 289

Yeah bro's but if people always just settled for what was available think of what we would have missed. besides its like imagining what you would do if you won the lottery..lol. most of us wouldnt have access to the Tech to do this anyway.

did any of you guys see the issue of 5.o mustang and superfords where the fox was getting 800 ponies and 20mpg highway with 3.73? maybe you could get some ideas off of that. if i remember correctly he has an auto tranny with overdrive...so that supports your idea of low revs on the highway.

Your biggest concern is going to be making sure you don't spend so much doing the actual project that it becomes more expensive than the gains. Some of this stuff ain't cheap, unless you'll be driving it dd for a few years make sure you do the math.

PS gears will be a big one on that list, especially for highway driving. Find some stock 2.73's

viper spec t56.... because of its .50 od

Yup, LOW o/d is going to be necessary to get "good" mileage out of a V8 with decent power(by current standards). You want some power and good mileage, get a 4 banger and put a turbo on it.

I still hope that this thread might generate some combos or more suggestions of single parts/packages, but:

Nitrous will not *increase* mpg, nor will it detriment it.

we got funky ignitions and turbos....those are the high dollar parts so far ???
(well I was thinking turbo from the start, see combo #1)

Not intending to be RUDE but yes scartastic: YES here are all the HIGH dollar expensive stuff so mentioned
WOW actually everything turned up being dirt cheap or stuff that mostly folks dont want....
(excepting the funky ignitions and turbos already mentioned which are good ideas)
Additionally low rpm's are inherently cheap because the engine doesnt have to be built "to the hilt",
"to the bleeding edge", its not going to need constant tunining either
Lightweight veh, well this is in the selection

*note my three notchbacks anyone*

also you can remove stuff thats free.... however I wont forget light wieght parts, tubular k-member, use of aluminum,
also (here's the expensive stuff) super lightweight pistons, and conn rods...


Other than that folks have been saying gt40p heads stock cams 289 internal parts.... off the shelf cheep stuff

Im just saying that if somebody puts together a combo here that makes sense Ill build it!





For one idea, do you agree that turbos would be better in this application than for example the new paxton sc?
