ok so i figured while im working on all the other stuff id see if there are fuel injection kits for these engines or if it would be relativly easy to make one my self or would it be insanly complicated i know some of these y-blocks used 3 bolt carbs and intakes and that gm throttle bodies are 3 bolt design for the most part so would it be posible to make my own fuel injection set up if i find the right parts let me know your opinion regardless i want to atleast try it

anything is possible...there are aftermarket kits that will work......it definatley is worth it if you know how to do it yourself as the installation and conversion is what takes the money...(labor is expensive)

ah so do you have any ideas on how to do this conversion i stated my idea in my post but i would like some more expirenced thoughts

I am going to use those 80's CFI 2 bbl throttle body carburettors from 302, it fits to 57 and later 2 bbl intake manifold. And for ECM I have built Megasquirt. It needs little work, but how much, I will know that when I have my engine ready.

If you want to make it easy on yourself, the FAST EZ EFI and Retrotek Boss EFI are self tuning systems that mount directly to an intake with the Holley 4150 pattern (ECZ-B, Blue Thunder).
Holley and Edelbrock provide fuel injection systems which have to be tuned. With megasquirt, you can do just about anything. There are the Stromberg 97 looking throttle bodies. If you can get a hold of an original Hilborn manifold, you can send that to Hilborn and have it converted to efi. Adapters are available to mount GM throttle bodies to a 4150 manifold and the GM computers are pretty easy to tune. You can make a manifold for multiport injection.
There are many options. It really comes down to your own ability to implement each system.

just like those kits.....i am converting my 85 chevy suburban to tbi and its all pretty easy for me as i can wire in a chevy truck tbi, ecm and sensors...the kits are even easier.

ok the 4150 kits are great if you have that intake but i have a 2bbl intake so am i screwed unlessi get a 4150 or could a guy make his own adapter plate to these

You can make, maybe even buy an adapter. With the 2bbl manifold, look at using a 2bbl gm throttle body. Then you can prevent the mixture from having to make some tight turns.

ok great does anybody know where to find the ford 302 2bbl tb or the chevy 2bbl tb?

Your favorite salvage yard, ebay, new from Holley. The GM units are plentiful.

ok. here's my two sense worth. if you want an already done up kit that has it's own learning curve, look into Retrotek Speed's efi system. here's the website: http://retrotekspeed.com/. this system learns as you drive. Now, what i plan to do is build a custom intake and install injectors into each runner. then adapt a ford 5.0 sefi system to it. I will utilize an aftermarket chip to alter the timing order for the efi and meld a 5.0 tfi distributor and a y-block distributor together for the ignition part.

Quite a while ago I got a 85 Ford pickup that was given to me with a early version of a Holley 2 bll. type throttle body F.I. system that was mounted on a 300 Ford 6. Its all there, I even have the manual and some other things that come with it. I just have to get it off of the truck its on ands convert it over to my 292 on my Unibody. That if it runs right should make quite a difference. Michael

I'm quite interested how you are going to install those injectors to your own intake. I'll be hard, but it sure is doable... . This is how I did that... 
 Fuel lines are another story too...

Now, what i plan to do is build a custom intake and install injectors into each runner. then adapt a ford 5.0 sefi system to it. I will utilize an aftermarket chip to alter the timing order for the efi and meld a 5.0tfi distributor and a Y-Block distributor together for the ignition part.
I know that the TFI module is required in the Distributor for a Ford Computer. I am real curious how the TFI module could be melded to a Y-Block distributor. Would the TFI housing be used instead of the Y-Block distributor housing? Would it be possible to alter the Y-Block distributor to accept the module and internals of the TFI dist?
Here are some other EFI questions I have had bouncing around in my noggin. Would a longer intake runner be better for a street driven car compared to the short runner noted in the example pics? I am only referencing this pics. The design looks great. If building your own intake. What design would work best for a daily driver street car. A 360, or 180 design. Is the 180 design only better for a carb application on a daily driver street car? It's my assumption all the EFI intakes out there are 360 degree. I have a complete 5.0 Ford upper and lower EFI setup. Harness is made for a retrofit install. It almost looks like I could build a lower for the Y to match the upper of the Ford. It would look odd, but functional.

I have wondered about the TFI distributor as well. They are plentiful in the salvage yards near me. I might get one one day and have a look.
If you're getting a chip to alter the timing order of the injectors, why not take the computer controlled timing function out of the equation at the same time? Or see about making it work with a locked out duraspark unit.
The runner length will mostly shift the power band around. Long runners, like the Chevy tune port shift the power to the lower end but they run out of breath at about 5000rpm. Great power down low. Great for the street. Short runners will shift the power band up, sacrificing the low end but the loss may be insignificant depending on the use of the vehicle.
Because multi port is a dry system, that is fuel is not carried through the manifold, only air, the manifold design is not as sensitive as it would be for a carbureted or throttle body injected application. This allows one to be very creative. I bet just about any design will work reasonably well.

Use TFI without Ignition control.
...or it might be possible to move TFI's trigger to crank and drive with normal locked dizzy in wasted spark style.
Edit: Sorry, I didnt think clearly, forget the wasted spark.
If TFI uses simple trigger and fire method without any tooth loggering, then you can just move triggering point to damper and drive normal dizzy and coil.
I used samekind setup three years ago.

If dizzy got 8 trigger points, then damper got only four triggers.

ok. On this website there is a link to yestertech's website for Jerry Christanson. On that website you will see a few pics of a intakes he's built. mine will be similar to what is shown. the throttle body will be mounted on one of those throttle body elbows made by wilson or proffessional products. as far as the tfi deal. I have looked at a 302 distributor and a Y-block distributor next to each other and I think housings are bout the same length. so my plan was to measure and splice the lower y-block shaft with gear on it(low stress) to the upper 302 shaft and housing. The thing with tfi is it's needed to fire the injectors. inside the tfi housing, there is a shutter wheel with windows and fingers. well, one if those fingers are lil smaller than the rest to tell the efi here number one cylinder is at. that's essential to making the efi injector firing order correctly.

Hall sensor in TFI
From fordfuelinjection.com
"This sensor is so accurate that cam changes can be a bad thing. The computer is programmed when to open fuel injectors in relation to the valve timing from PIP. Changing the valve timing with a cam swap won't be noticed by the computer. So optimal performance and idle will not be to their true potential."
Sequential fuel injection brings only a little better emission rate and maybe a little better fuel economy, but who can time it right? When flooring the pedal, all injector are over 80% at time open in all systems, then injection timing is not an issue.

I don't know of any website for Yestertech/Jerry Christenson. Jerry doesn't even own a computer. I found the link that you are referring to. Ted posted it elsewhere. My question is how would someone find that link if Ted hadn't posted it?

at the home page for y-blocks forever, under links at the bottom of the page. link to yestertech. that's the one i was refering too.
