KK1201 - The 1st Boss 429 Prototype

[EZ Nova]

Sorry don't, mean to insult anyone, but please explain to me what this car is? I caan follow it's a KK numbered car, but if it retains the #'s matching 428 what would be related to Boss 429? Are the shock towers moved like a Boss 9?

It's a prototype. 1 of 7 prototype Boss 429s. Each car had its own purpose in developing the Boss 429s.

If you look at other EARLY prototype Fords from this era 1201 falls right in line with them. Shinoda's Boss 302 prototype had a 428 CJ. The Boss Bronco didn't have a 302 or 429, it had a 351 Shelby engine. This car retains it's numbers matching 428 CJ.

As stated earlier we're continually seeking information and researching the car. We know the car has rolled fender and quarter lips. The build date was exactly the same as Knudsen greenlighting the Boss 429 program. Due to the massively condensed timeline Ford had to get quite a few balls (Mustangs) rolling to move the project along with expedience.
It's likely this car was built in order to get the 15x7tire/wheel combo rolling. It may have also been a test fitment car for the 429. Maybe something as simple as "Let's test this 429 to see if it fits in the brand new 69 Mustang body". Remember, as of August 20th, 1968 there were likely ZERO 4-spd, staggered shocks cars in existence beyond my car.

So what I've been doing is posting as much information as I have on the car in as many places as possible in front of as many experts as I can. Doing this yielded the information on the car being used as the molding mule for Ohio Georges 69 Gasser. It's my hope that more solid documentation will come forth regarding the cars time at Ford, which seemed to be the whole model year.

What we have for sure is hard documentation with the car on a "BOSS 429 VEHICLES RETAINED FOR COMPANY USE" and a "BOSS 429 VEHICLES" list. It also appears on lists for "SPECIAL VEHICLES ACTIVITY DEPARTMENTAL VEHICLES", "1969 428 CID COBRA JET MUSTANG - SPECIAL" and "STOCK VEHICLES DEPARTMENT SPECIAL VEHICLE ACTIVITY - VEHICLE ACCOUNTABILITY".

What was your question again? LOL

Lol thanks. I have no idea about Ford stuff. So are the shock towers moved?

No. Any of the altered shock tower prototypes would have likely been destroyed. This is the only confirmed surviving KK car, 1201 thru 1207.

This is quite a find and rather amazing it has a numbers matched 428 in it if it was used for drag racing and a Boss 429 test car. If the towers aren't moved the Boss obviously never got installed.
That mostly blank data tag is bizarre too.

I hope you can keep us updated as you find out this cars history.

Agreed. When Mustang experts tell you they've never seen another like it you're left wishing your car could talk.

I wish they could talk. We'd probably hear some crazy and cool stuff!

Wow, what a great find. Interesting tag and I notice it doesn't say it's a VIN. Does the car actually have a title and registration?
