Are there any fuel injection setups on the market for slant-sixes of the 60's? Thank you.

Yes.


The 4.0 Jeep injection can be modified and used on a slant six.

The aftermarket EFI setups like Comp XFI and Accel could be readily adapted. Injector bungs can be installed in an aluminum manifold and the rest put together from off the shelf parts. A bit spendy though.

One of the guys at diyautotune.com has a megasquirt on his slant 6. You could do it for pretty cheap if you threw an 80's/90's GM V6/V8 TBI throttle body onto a 2bbl slant 6 intake. Would just need to buy or make an adapter to get them to bolt together.

Back in 2006 I did an EFI /6 for Mopar Muscle mag.

It was a little different from what I would do today, because at that time I had to come up with a method for generating the crank signal from a uni-light distributor. Now I would just bolt of a FAST EZ-EFI for port injection and run a stock style ignition. That way no modifications would have to be made to the ignition and it would self learn.

I was just tossing up the idea for when I get an automatic car in the future (granted I am driving in traffic). Basically my only thing is trying to get a little bit better fuel efficiency and better cold starts.

I was curious about this topic as well. Somewhere down the road I wanna do a Turbo EFI slant in a pickup, and would prefer a MPFI setup if at all possible. I came across this article DeBiase EFI for adapting the GM 3.8L MPI setup. I was curious about the Jeep 4L route, because I have a 92 Grand Cherokee with a 4L that is just sitting on my property and would like to find out if I can use that setup instead

I understand, I'm in a EFI turbo slant build right now.
But in all honesty if I started over, a hot turbo 2.2 is the better choice, IMO

A problem I am told and I addressed, efi on an alum intake has potential for injector heat soak, mainly on start up, with nearby exhaust

Here's an Updated link for Richard's article.

6 year old thread, but... you can use the Jeep 4.0 in a truck. In a car the deck height might be a problem if you enjoy being able to close your hood. If you are keeping it stock, the Jeep efi system is easy enough to dissect and transfer over. Transmission selection would rule out stock mopar transmission however there are other swap options that would work.

Has already been covered and has a video attached in the first reply in case you missed it.

I helped a buddy build an EFI system on his 68 Barracuda. He used a Mega Squirt box, S-10 Blazer throttle body, a Clifford intake, and the in tank pump setup. (Welborn maybe)

He bought the tool for doing the injector bungs and fuel rail, and I used my buddy's Bridgeport to do the manifold and fuel rail.

He's had some issues with the MS box but they took care of it for him. He's getting it tuned now to where he is very happy with it.

Educate me on the various six cylinder engines.

How do the AMC 4.0 I6
Chrysler Slant I6
And Dodge truck 3.9 V6
Compare technically?

Which made more torque per cubic inch?

Which was considered smoothest?

The slant six has achieved legendary status for durability
But can AMC I6 engines last as long?

Aside from the engine factory tooling issue of making the 3.9V6 alongside the 5.2 V8
would base Rams and Dakotas have sold better if
they had updated fuel injected slant six engines
rather than 3.9 V6s?

Would a slant six diesel have made sense?

I think the AMC 4.0's are the best of them. Good torq, good hp, very dependable and durable, fuel injected. The slant's were reliable and fit under the hood of a car but only made 1/2 the hp.

As far as why dodge made the 3.9 instead of updating the slant, the dakota is the only reason I can come up with. Either the dakota was originally designed around the 2.2L and later they decided they needed a 6 cyl and the slant was too long or from the get-go they decided they wanted a shorter hood on the dakota. The decision making process at the time really boggles my mind. Here for the 1987 model year they debuted the 3.9 V6, carbed at 125hp which was less HP than either the fuel injected 2.2 turbo engines or the fuel injected mitsu 3.0 that were both available that year making 140hp. Then in 1990 the 3.3 V6 comes out at 150hp and the next year the 3.8 V6 comes out. They spent millions on developing the 3.9 really for no good reason and it wasn't any good of an engine anyway. I don't know if the fwd and rwd departments just didn't communicate and share or what because it seems like one big waste.

They didn't spend crap on developing the 3.9, go read the story at Allpar, it will answer your questions.

There have been a few guys over the years that cut up Hilborn, Crower or other "stack injection units and adapted them. Others have used injection from 4-cylinder midget dirt cars (takes 2 of them!).

I've been thinking this would be cool to do on a /6 as well. I've got an Eaton M112 supercharger system form an 09 Range Rover loitering in my garage that would be sweet adapted to a 225
