Well I finally finished up this adventure and got it running. I used the EZ Efi system from FAST. It is fuel injection for dummies.. Very easy and trouble free. My home made hack and bash manifold seems to work fine.. I learned a lot about EFI and how it works. The engine fires right up and idles much better than the 600 Edelbrock that was on it. It made 325 horse with a Blue Thunder intake when I tested it in 2010. I hope to dyno it next week and see how the EFI compares. Then I can go about tidying up the appearance. A rats nest of wires currently.

  

 

Looking good Royce.  The dyno numbers should prove to be interesting.

I thought ez efi used a 4 barrel throttle body. Do they make a port ez efi now? I don't see it on the site.



Nevermind. Found it. Cool!

Well done. What was the actual cost of that set up?

Seppo, the controller, wiring, and all the sensors was $900. Jerry C. gave me the manifold. An ebay pump and regulator about $100. The injectors are mustang, used, free. Throttle body, 75 mm for a 302 $80. Plumbing and hoses $100. Injector bungs $3.00 ea. Many hours of time,swearing, scratching head, and ham fisted fabricating... $0.00

Very cool!  I've had my eye on the EZ EFI throttle body set up as an easy way to bring reliability and driveability to one of my old cars, but this new multi-port option seems to open up the possibilities even more.  Now if I could just open up my time and budget!  What kind of interface does it require with the ignition system?  I seem to recall reading that these EZ EFI needs a very clean tach signal or something like that...are you using stock ignition?

Good DIY project, Thumbs up!

But sooo expensive. Check this out http://fordfuelinjection.com/ . Ford's own system is very versatile and cheap as mud and you can convert it to almost everything. Intake manifold is the greatest challenge if you are planning to do Y with multiport, but it sure is doable.

And what did our Megasquirt system cost. Two Mustang throttle bodys about 50 euros, Mega itself about 200 euros, wide band oxygen sensor about 70 euros, TPS sensor, IAT sensor, temperature sensor and some other small parts together about 50 euros. Intakes cost about 20 euros from material costs and as I welded it by myself the building costs were zero. Eight 19 lbs/hr injectors cost almost nothing. Say 50 euros. This is here in Finland, where everything is expensive but there you can find everything from salvage yards for almost free, so...

When I put the 92 roller motor in the Falcon, I gave away the EFI set up, to be able to run in the stock classes, and now I regret it, as I could have adapted it to my 312..57 Fairlane.. Have a Son Inlaw who is a TIG welding fool (owns scrubs) 

Brother and I own/operate 1957 Ford Fairlane 312/4x2 and two 1963 Falcons 302 rollers carburated 600cfm, FE427 sitting in shed..

Ok, just for a thought... This is what I'd do if planning EFi engine for a cruiser:

(And ofcourse if money wouldn't be a problem )

Mummert intake

Wilson 90 degree elbow to fit that intake http://www.wilsonmanifolds.com/products/throttle-body-elbows-/cast-elbows/4150-cast-elbows.html

Wilson 75 mm 915 cfm throttle body to fit that elbow http://www.wilsonmanifolds.com/products/throttle-bodies-/single-bore-throttle-bodies/square-flange-throttle-bodies.html

Wilson TPS sensor http://www.wilsonmanifolds.com/products/throttle-bodies-/throttle-body-accessories/tps-components.html

And then simply drill four big enough (90 lbs/hr maybe?) fuel injectors on sides of that elbow to feed the hungry Y. Fuel lines to those and then some Megasquirt stuff to control the fuel flow.

Ok, then we need also fuel pump http://www.jcwhitney.com/high-pressure-110-fi-electric-fuel-pump-for-fuel-injection/p2029030.jcwx

And a regulator for that also and of couse the one that is also boost sensitive

MSD pro billet to control the spark etc... Should work fine or then something with crank triggering to get things controlled by megasquirt and to get traction control, anti lag and etc...

And two huge turbos to give some boost

And of course all that expensive stuff could well be done with cheaper and home made parts also.

Just dreaming...
