6/8 cylinder EFI engine?

Do they make a 6 cylinder efi engine? I dont really care which engine it is, ford or chevy will do.

I want to build a daily driver truck. I was thinking a c10 maybe a flare side. My dad wants me to get an f100. I personaly just want something comfortable.

I dont want to race it or burn the tires. I just want somethign to go from a to b LOOK cool and be as reliable as posisble.
I am not going to road trip in it.

I was thinking efi engine for reliabliltiy and a huge reason good MPG.
any ideas? thoughts? comments? please dont lecture, i have been on these boards enough to know the same general comments.

Well, I had a '96 F-150 with a straight 6cyl and I'm sure that was EFI. Are you looking for a stight 6 or a V-8?

Yes when it comes to a fuel injected V6 the choice is yours. All of the big three makes a V6

Most common are the

1. GM 4.3 Found in most S-10 pick ups.

2. Ford 4.0 Found in most Rangers/Explores.

3. Chrysler 3.9 Found in most Dakota trucks.

Plus all of the imports that you could chose from...

If you are looking for MPG I would look into a Import V6. Toyota makes a strong running engine. The 3.4 in the Toyota Tacoma would be a good choice.

Hope this helps

Steve

i WAS HOPING TO STICK with chevy or ford. I have a engine management system already for a ford harness but it can easily be used for a chev. That way i can control the fuel injection and play with the ecu alittle bit.

i was thinking of a mustang engine maybe. Id really like somethign that i can purchase some mounting kits for.

I wanted to add something to this.
The car and engine/transmission setup i am looking for:
it would be best if i can just do a bolt on. I definately dont want to make any custom parts for a boring 6 cylinder.

if maybe an f100, c10, or some other pre1973 ford and chevy truck had a 6 cylinder it may be best to go with that sme engine and vehicle setup, even if i had to screw the efi

If someone has experiance with a 6 cylinder in a pre1973 truck please post all the details possible

The Ford 300 (made from 1964-1996) had EFI at the end of the run and would fit easily in a pre-73 Ford. I forget what year they put the EFI in but it wouldn't be that hard to find out.

The fuel injected v6 they make now would probably fit fairly easily as well, the 4.2L Essex motor was based off the old 302 architecture.

Don't know if Chevy went EFI in their straight six at the end but that would be a fine motor too. Hard to beat a straight six for smooth.

In terms of getting the best gas mileage which would be best and by how much benefit:

fuel injected or carb?
6 cylinder vs an 8 cylinder. Does displacement have anything to do with mpg?
for example, would a 4.0L v8 and a 4.0L v6 get the same gas mileage? or do those extra cylinders make a big difference?

what kind of mpg do most of these 302's in a truck get?

I think Chevy used carbs on all its inline 6's. Clifford has EFI systems, but they're ~$2K. Ford used EFI on some later 300's, so that might be the way to go if you want an inliner.

I was thinking about doing this but i have had a bad experience. When i had a 73 bmw 2002 i converted it to fuel injection and ran the megasquirt EMS, all the hardware work was a pain, i dont know how to weld so that was all extra $$$ spent.

I was thinking of finding an EFI engine so that the install would be easier. I was trying to make this a budget project though (((

The chevy 4.3L 90deg V6 is basically a 350 with the 2 cylinders hacked off. Mounting brackets and accessories are all the same.

Do you know what year it was made?
what cars it was in etc etc.
that is the answer i was looking for, it may not be the best option but i am definately interested.

Now, im wondering how much the 6 cylinder vs the 8 cylinder gets in terms of MPG in a 3,000pd truck

started putting in EFI in the 300 6's in 1986 or 1987.

From about 85-04 in s10's, Astro's, Full Size, etc.

My guess is you will get around 16/21mpg city/hwy if you go easy on it and keep it in tune.
