View Full Version : Seeking wisdom on a Ford experimental SC part that probably no one has ever seen‏

OK sent this to the contact info last night thinking the board was a pay only site for sc owners but this morning got the automatic reply that said its free to join so I did.



Now that I have your attention :)
First my name is Curtis, I'm ex army crewchief, ex tech rep, ex fixed wing mechanic and an engineer that hides in his garage and builds custom parts, restores parts and happens upon weirdo items. I'm also a moderator/resident fabricator over at Galantvr-4.org and you can find stuff I've built for doing a google search for "galant vr4 curtis" or "one lap vr4 curtis". Yes helped some guys with some parts for the one lap of America.


I've been doing gearhead things for over 25 years now and just stumbled on a few boxes of old parts a guy had. These were left in his garage by the former owner at first glance was nothing special a bunch of ford 289/302 Flat tappet cams, some new 2.3 stuff and a box of SC parts and a receipt from a ford dealership in Dearborn MI where the 89 Thunderbird only had 17834 miles on it in 95 so this was the guys baby for sure. So I figure the guy was either a designer / engineer at Ford for the SC's or at motorola in the smart guy dept.

SC box had 2 cams with some numbers stamped on the back end and one had a number scratched on it that said 19G, some keepers and spiders, I think some lifters as well and a strange ECU. First thing I noticed was a door on top so you can open it up quickly. I took out all the screws and found that the chips on the board are socked like the guys have been doing to the Mitsubishi's for years so the chips can be pulled and replaced instead of having a chip tapped on to the side like my old Mustang had.
On one of the chips has a sticker
GURB-R5 OC
07B1
495 AOD

With a yellow junkyard pen had 3 8 super then something thats worn off and 3 1 . 89
then a sticker that said motorola confidential proprietary
Then with a fine point pen had Auto Trans 7-24-88 Supercharged written on the case
Then where the normal EEC-IV sticker from Ford should be it has a motorola sticker
It has the motorola Inc and logo then says Engineering sample
EEC-IV SFI-MA11/13 XF-287573
PT-A1914GMA11/13-02-233 19G88


So I figure the cam marked 19G is for this computer.

Just wondering if you guys have ever heard of such a computer with a custom matched cam, or a socketed board and what something like this is worth in the SC world?

Also I found this morning in another box was a set of rods and pistons as well as a blower outlet. I also measure the lobes with a pair of calipers and the one cam does have a higher lift that the other. I doubt it will give 100mpg or 1800 hp but is bigger.

If anyone has a cam laying in there garage, if you could please measure the intake and exhaust lobes just to give me an idea if these are much larger

Just give me a yell back here or a PM over at Galant VR-4.org sent to curtis


Thanks for your time and wisdom. Curtis

I also have some pictures I just took if someone wants to post them for me I can email you. New to this type board and can't seem to figure out the image hosting part. Thanks Curtis

Sound cool. If you want to post pics you will have to use photo bucket or something like that.

Hello Curtis,

Welcome to the forums and although I have no idea what you got there I would be more than happy to help you host/post the pictures you have. Please send to dboydma86@yahoo.com and I will post them ASAP.

Hopefully someone with more knowledge on this will be able to help with the pictures.

Dan

Curtis,
Hosting images is really easy. I'll show you a couple steps so you can post pictures and know in the future.

1. Go to a photo hosting site (I will use imgur.com as it is my personal favorite and easy to use)

2. Hit the "computer" tab, and find the photos you wish to select on the pop up box, select the photos and hit "upload"

3. copy the BBcode given, looks like this "[ IMG] http://i.imgur.com/ssHRa.jpg [/IMG]" without the spaces

4. Paste it into a post here, and you're done.

I have seen an EEC like that before. Some of them made it into cars that were owned by engineers from Ford just like you assumed. I can download the calibration and compare it to a production version if you wanted to send it to me. Unfortunately only Motorola and Ford had the replaceable chips to put in the EEC so for us to do anything with it we'd be putting a typical aftermarket chip into the J3 port like you did on your Mustang.

Published cam specs for the SC were .424" intake and .447" exhaust which would be .245"/.258" on the cam itself. Stampings on the end of the cam were generally lot #'s for the original forgings and not representative of the final grind, ie. not a part number. But yours might have additional markings if it was custom/experimental.

Dave thanks that helped

I measure the first cam that only had the stamped numbers and is came out to be
1.7020-----1.457-----.2450 Intake
1.7150-----1.457-----.2580 Exhaust
Then the cam marked 19G is
1.7125-----1.457-----.2555 Intake
1.7195-----1.457-----.2625 Exhaust


So the 19G is a performance cam compared to the other which was stock. By eyeball reference the lobe separation looks to be the same but just damn hard to tell, I really wish I had a 4th axis on my mill so I could use a dial indicator and really figure out the duration and everything on this.

Now going to go look up spec's on the aftermarket cams to see how this compares. Thanks guys.

Well the guys I know with the SC cars weren't interested so I put it up on ebay along with alot of other stuff I don't need.

click me (http://www.ebay.com/itm/Experimental-ECU-ECM-3-8-Thunderbird-SC-Super-Coupe-upgrade-Cam-Camshaft-/330688546033?pt=Motors_Car_Truck_Parts_Accessories&vxp=mtr&hash=item4cfe92c4f1)

Good luck with the sell. I'm not sure you will have that much interest at 300 bucks.

The thing I like about this is that it kind of proves some of the rumors we've heard over time that some of the SC's that were driven by some of the engineers might have been "ringers". Cool info. I'd like to have the stuff, but I could only offer $150.

The hand written label on the eprom means it's revision 5 of the 'GURB' strategy (did this ever make it into production?). Not sure I'd want to run an engine on an experimental strategy :D It would be interesting to see the code though.

The J1 connector label suggests the ecu is some kind of SFI-MA11 / SFI-MA13 hybrid hardware.
