Fuel Injecting An IH Inline Six...anyone?

Anyone in the pulling community ever done port fuel injection on an IH six gasser?

Reason I'm asking, I've got a truck with a BD264. I know the BD series sngines are quite similar to the C221/C263/C291/C301. I'd like to go to fuel injection, but I realize that throttle-body injection wouldn't be much more efficient than the stock carb...BUT I also realize the IH sixes have shared intake ports.

So I'm wondering...anyone ever injected one, and just used 3 injectors [and fire each injector twice as often]? I'm looking for something I can run on the street, not a 6000 rpm screamer. If someone with a little experience would let me "pick their brain" for some advice, I'd appreciate it.

If you can figure out how to do direct injection,....well now that would be the cat's meow right there....
 
I figure some "guru" could use a General Motors ECM, after converting to electronic ignition. Then the setup could be programmed with something like the MegaSquirt software. I was just hoping somebody else had already "been there, done that" and was willing to talk about it.

I've seen the Keystone turbo setup, and it seems to be pretty slick. I'm just thinking that gains could be made in power and economy by electronic fuel management.
 
Buzz, im a fan of ford fuel injection. i do belive that its possible to build a wiring harness using ford ecm n either speed density, or mass air system for the 221-301. i built a fuel rail, pump n wiring harness, and was down to either making a custom tuned intake n exhaust, or modifying a down draft manifold, and modifying a 300 inline 6 distributor into the farmall. ive got that far, but kinda lost sight of it. megasquirt, is a simple system good for the gm throttle bodies, i dont know if ms can control ign timing, or injector timing to tune best, while ford efi, can learn n adapt.
 
I have a picture of a JD BR with a GM electronic fuel injection and ignition system retrofitted.
I'll try to post the image. Looks like factory built.
 
I know a guy that went to the dyno to "MAKE" EFI work,66 pulls later he has 500 hp out of a small tough engine,at 5grand,their club limit.Other big name national pullers tried and gave up.
 
Thanks for that advice.

One step towards EFI is electronic ignition. Now, the Chevy six distributor can have the shaft cut to mate up to the IH six...but the IH distributor rotates the opposite direction. Now...AMC sixes use approximately the same distributor as the Chevy six, but AMC eventually went to the Ford Duraspark distributor. Same reverse-rotation problem, as far as spark advance goes. But I'd think that a Duraspark distributor would be a better starting point than the Chevy electronic.

I have a Duraspark out of an AMC six.

Until I recently sold it, I had a parts truck with an extra "core" IH six...so I was thinking about modifying the original downdraft intake from my parts truck. Now I'm just wondering if I was crazy, thinking it could be done.
 
thats where i stopped as well when it came to a distributor. i thought of mounting a distributor horizonally where a tractor governor would be normally located. using a distributor from a 88-92 300 inline 6. those have the pickup inem to signal the ecm to operate injectors n automatic timing the ecm is capable of. 99/2000 jeep 4.0 has a simular sensor that replaced the whole distributor that does the same thing in a smaller package which would allow the use of coil packs instead of a distributor. fuel rail, throttle body and port injection is very very possible using speed density, or mass air ford fuel injection systems. i was thinking of crank trigger ign, with triton coil packs too. maybe i need to work on this again sometime. lol
 
What would possess you guys to want to Phart around with a distributer?
Use three of those dual coil packs. The ECM calculates the spark advance and is programable.
 
Yeah, I know GM built a lot of engines with those coil packs. They also built a lot of Vegas, too, but that doesn't mean they were worth a damn, either. My experience with coil packs on an '88 Olds 3.8 were NOT positive. Maybe they're better NOW...but if they could get by with building junk THEN, why should I expect anything different NOW? They fooled me once; shame on them. Not sure I'd want to let them fool me twice.
 
thats the best part! junkyard part shopping! I think the coils from the 2.8 n 3.1 gm v6 arent that bad. bad thing was, when an injector died, it shutdown the whole engine! spent 2 weeks learning that on a 91 lumina. i drive ford for everyday vehicles. so far, just change the oil n plugs n been good to me so far. anyways, it comes down to, how to get a pickup signal from the engine, to the ecm. distributor, magnetic pickups, (crank trigger) will work either way.
 
We have a tractor pulling with the Ford ecm. Just mount the 35 tooth sprocket behind your crank pulley. You are right those coil packs are neet, and really hot! Just google Ford crank triggered ign. The link will lead you to the fuel injection to go with the ign. All for about 300 dollars and a Donor 6 cyl car. You control it with your laptop, or what ever. Vic
 
Based on my prior experience with GM coil packs, I think the Ford EDIS setup sounds like the easiest conversion there...
 
trigger wheel can run injectors, no ecm needed in a simple form of efi. 3 injectors drilled into the cyl head at the ports, another 3 in the intake, tuned by rail pressure by adjustble regulator. crude, but it would work.
