For starters, you have a computer port in your 78? Did you swap to an EFI/E4OD combo? Secondly, I'm not a big fan of chips in gassers, anything you can afford won't be worth it and anything worth it (still negligibly IMO) won't be affordable.

Gonna need more details on the PCM, but any way you look at it, they're generally not worth it (the kind you just order and pop into the J3 port).

CAI, Free Flowing exhaust, different gears. These will net you MPG's, a simple chip will not do much. BUT a "tune" with the listed mods will give you more MPG's and give you more performence(except the gears). Gotta spend $$ to make $$ or in your case, save $$ lol.

ok that was wondering without really asking directly if it was worth it or not. In reality i think im screwed either way cause I'm planning on putting on bigger tires and lift before school starts. the nice thing is i will be over 400 miles away from home so i wont be driving a long distance everday.:rockon:rockon

You even have to be careful with those...there are a ton of designs out there that do nothing but suck hot air in from the engine bay and hurt you more than anything.

Well the tires and lift are gonna help your gas situation:doh0715: Why not save the money for the lift and tires and buy a 4 banger 5 spd Honda Civic if you're worried about gas? Seems like you went from one extreme to the other...on one hand you're worried about mpg's then you're going to go and do the exact opposite of improving mpg's. I mean hell, a decent set of 35's will run you $800 and a good 4" lift will run you $1000, you could definitely pick a gas sipping beater for that.

I know the tires and lift are going to make the mpg even worse. but if there is a way to run 40-44 tires and have some what same gas milage still keep it above 100 ftpg then id like to keep that option availible. Oh and for the beater idea have it under cover bought a geo metro for driving home and back from college. and plan on driving the bronco up at college.

So you're worried about mpg's but you have the cash to drop on 40-44" tires and the accomodating lift and accessories? You realize, you're easily staring 5k in the face, right? Not to mention regearing. And seeing as you asked if you had a chip with your 460, I'm gonna assume someone else is doing the work at $80/hr. So were you hoping a chip would be the magic fix all that boosted your mpg's and then the lift and tires would bring you back to where you were? Or wtf was the point of any of this?

OK no need to be a dick about it. and yeah i have the money for the lift and tires. which isnt any of your business. and my uncle is the mechanic and im going to be there helping. so no labor cost. second the cost of gas is a minor problem just curious on any ways of getting better gas milage once i get everything done that i want. so thank you for questioning and being a dick about it.

You're welcome...You drive a brick, with a thirsty engine. You want better mpg's drive something else. But go ahead and use a chip, might wanna use one of those tornado things too...while I'm thinking of it, try the Fitch catalyst, and I'm sure your mechanic uncle can install them all. You might also wanna try a dual fuel set up and give the water4gas site a once over. Don't forget to plaster your rig with the go fast stickers to really utilize the power from that BBF. Shoulda probably just asked that uncle of yours what the best chip was for your 78 460:haha

He's from Lapeer. They're lonely up there in the thumb. :rofl:

OP, you have your priorities all f*cked up. You CANNOT have a huge heavy (lifted!) truck with a big block engine and ridiculous-size mud tires on it for an economical daily driver. Physics is your friend, so use it: go with a smaller vehicle that's going to be up to the task of getting respectable fuel efficiency, last a long time without falling apart, and get you where you're going reliably. Trust me, I know WTF I am talking about; I've been keeping my eyes open for a 2004+ Honda CR-V to replace the Bronco, since even at 18-20 mi/gal in the truck, I still need better efficiency (and reliability...so sick of driving a rusty-ass heap).

I certainly hope you're not a science, bio, or engineering major.

Hey guys, I'm not trying ot get in the middle, but can we get back on track to the OP's origional question please. FLAME FREE ZONE. To the OP, do like I said and invest some money in a CAI that sucks "cold air" not an under the hood filter, try fabricating something to sit at an opening in the engine bay wher eit will get tons of cold air during the 400 mile drive. And get a better flowing exhaust, "breath big-exhale big" that is the name of the game for performance and better MPG's. Don't wate time with a "chip", you need to look into a tune or piggyback chip(I'm not sure if the obd1 system has a re-flash capability or if you have to piggyback chips)BTW these mentioned computer modifications are actually tuned to the computer PCM and NOT the chipos that are plug n play, just clarifying. Those 3 items: CAI, Exhaust, Tune will get you better MPG's no if and or but about it. Next, but harder to perform is the gearing. Gears will net you the best possible MPG's but are waaaaay more expensive than an exhaust CAI and tune combined as you have to do the front/rear gears at the same time. I am by NO means a truck specialist, but with my 95Z28 LT1 I get way better MPG's with a full exhaust with headers, CAI, and NO tune with 3.73 gears, than I did when I bought it 100% stock. So do the best you can to get ALL of the mentioned items and have a pro do the gears and tune, the exhaust and CAI are stright forward and simple enough.

EDIT: Just saw you have a 78, probably won't be able to tune that the way I am referring to sorry. I thought you had a 86 for some reason. My bad.

Whoa whoa whoa, it's difficult to try and answer a guy who's tune and plans change with every post, I was trying to get the info straight and then the newbie started in with the name calling. Not a wise tactic when asking for help.

The short of it, there's no computer to use a chip. You drive a brick that's going to top out at 12mpg's in stock form. Now couple that with a monster lift and tires and a regear, you're looking at an easy 5k in parts alone and you just cut your mileage to half at best. Now you're driving around a pavement pounder with zero power, so you're going to want to spice up that 460 to the tune of another 3k minimum and you'll probably lose another mpg or two. Then once you start breaking things, you'll drop even more coin and need to beef up God knows what which adds more weight further dropping your mpg's. So if you want it as a toy, great...but if all your plans come true, you'll be luck to have a 4mpg rig.

im not a huge knowledge person.
Someone needs to sig this or put it in the quotations thread.

Everyone loose the tude, the mods are watching you. :smilie_slap

To the original poster.
If you are asking this about your 1978 Bronco, the answer is unless you or someone else converted it to EFI, there is no computer to install a chip in.

as soon as i read it i was like wow. i meant to put im not a huge truck knowledge guy. after reading my original post i completely wrongly worded how i wanted it to say. 7.2 isnt killing me i just was trying to see if you guys knew of anyways that i could have this monster and still obtain some mpg. i know that having a huge vehicle isnt ethical but in my surcumstances im able to have it. and drive it daily. My dad tells me its not smart i should sell it cause of the gas miles but im stuborn and im sticking with it. ok yes im a newbie and have gotten some advice from my uncle but what other things do i need to look for besides the lift,tires, drive tearane and where can i go about finding them??

The most cost effective thing to do to obtain some pretty good MPG numbers would be to swap in a big 6 and a 4 or 5 spd.

Nobody buys a 460 for efficiency.


What carb are you running? Just keeping your foot out of the secondaries will help as well as regearing your axles to match the tire size.

Seriously, the cheapest, easyest, and by far best way to get better mileage is to loose the lead foot and drive smart... Accelerate slowly, and cruise at a good RPM on the highway. I notice that when I am consciously paying attention to this, and driving smartly i can get about 11.5 mpg, but if I drive like I normally do (which is w/ a kinda heavy foot, but really not too heavy) i get about 9.5 mpg.
