5.0 CFI to SEFI Upgrade

Jerry, all of my distributors have a date code of E4....I'm betting there is no difference in them save for the gear being made of iron and steel...

the one thing I know for sure...
I just learned a ton about a distributor today

I never did find my old distributor(s)..possible I never had any. Anywho, the engine that I had from the truck I mentioned earlier had date stampings of '79 on the pistons...like I said..s metal.

The distributor I took pics of above, I made a mistake...that's from the "50 dollar" 5.0 that had water in 2 cylinders. It was an '89 or '90.

I found the dizzy from the engine on my stand..it's much cleaner, by the way, and a quick inspection shows it to be the same as the one pictured above too.

Also has an E4 casting...in fact, all 5 of the dizzys I have do...even the one on the HO that was in the Sport. Even if the vane is different, odds are it's going to bolt to the distributor...barring a stator variance, which Lou points out as being same '84 up, I'd say you've got this one wrapped, Jerry.

I just got home and read all of the new stuff since my last post. I too have learned a bit.... Thank you to all.

Is this an answer to my post?

Yes it was, sorry, i forgot to quote you.

Wow lots of info posted here.

I wonder if a late 80's to early 90's f150 dist would be an exact swap for this application? Then you could use the lower and fuel rail and dist, have batch fire and keep the stock cam.

I suggested that a while back....

Depending on year, you'd have to take into account remote TFI, and it's almost embarrassing to say that I don't remember which dizzy gear they used before the roller engines came online in '94...

This thread is pretty informative, and I have a hunch we'll find out that he can use his distributor with the port FI setup, as long as he doesn't change the cam. However, should he ever upgrade to HO specs or above, he'll at least need to convert the block to roller lifters and change distributor to one from a roller 5.0....

Other than that, he's likely got it solved...hopefully. :)

are the fi50 distributors the same length as the one in my car?

But the whole point is to convert to SO SEFI using the orig cam which means the signature PIP is required and apparently vane disc is different in batch fire & CFI systems... Easiest by far is swap disc into orig dist, that way one is sure the gear material matches... Tpuppies the finger is also a good alternative...

From '85 or '86 up to the remote mount TFI all 5.0 dist are same, only difference is gear material and apparently the vane disc that's being discussed... 5.8 dist are longer and do not fit a 5.0...

To be sure gear material matches, I'd keep the orig dist and swap vane disc or trim the finger...

And in an earlier post, I said something about marking the vane so it could go back on the same way..
Well, after looking closer at the one from my project engine, I realized they only go on one way...there's a raised section that fits into the vane...no way to put it on wrong.

I'm going out there in about a 1/2 hr....I'll take pics

here they are side by side.... the one on the right is from my 87. the left is the 85
the vane from the 85 is turned 180deg from the one on the right

I did some measuring, and found that on both, the spaces measured just shy of 13mm more or less.
The spacing on the vane from my 87 is just shy of 16mm between the #1 and #8 (I'm assuming)
85 has an 8 stamped on it.....(assuming for 8 cylinder)
87 has an #8F stamped on it....(assuming for 8 cylinder fuel injection)

I tried my best to install both of these incorrectly... cant be done. the elongated slots are in different positions measured from the center
the 87 vane was a direct swap for the 85 vane, no matter how hard I tried to put in in wrong

here is the vane from the 87 in the 85 dist
rotor is in the same position that it was on the other vane

conclusion...... I need to get a vane from a fuel injected distributor, and this will be doable

So surgery on the 85 is not an option?
