67 GTA window sticker and invoice

[500575]

I purchased a 67 GTA that had been sitting since the original owner died it is a S code car and that is where my confusion starts the window sticker and invoice both show Base 289 2V 8 CYL engine at 105.63 followed by390 4V Thunderbird Special 8 at 158.08 the problems are 2 to me 1 you have to add both prices to get the total this is also true on the invoice 2nd it has a 428 bottom end with 390 heads the 428 block has a late 66 casting date and looks to be factory installed we found this when we pulled the engine to rebuild and nothing would fit any ideas thanks Tony 500575

Well all s code cars are 390 4V cars. A 428 passenger car block and a 390 block are the same thing. What made the 428 was the bore and stroke. You have a typical 390 car from what I can tell in your post. There where lots of FEs made in the 60s tons of 390s and regular 428s. Your cobra jet, and PI, blocks are different with extra webbing and things like that. With a casting of 66 though you don't have one of those. The Cjs where not made until 68. That is the best I can do for you. My dad would know more he is on here hopefully he will read this.

Ask Terry (tplusa..CA Chapter) not much about those years he doesn't know!! Good luck

the problem with tat is it is a 428 as in crank pistons ect

[spankmaster]

428 crank fits right into a 390 block. Like I said they are the same thing. You might have a bottom end from one of the passenger cars that had 428s in them from 66. No factory mustangs came with them until 68. There where tons of 66 428s in your big cars and trucks. There is a huge differance between a 428 cobra jet that came out in 68 and your regular 428. If you are going to go for lots of power you need to get ride of what you got for the CJ stuff. If you are just doing a stock build then you are fine with what you have. If you what to put it back completely stock then you need 390 stuff. But somebody put that in your car it was not factory like that. Are you sure you have the right part #s?

100% also you misunderstood if you thought I said I had a CJ it I just said it was a 428 my confusion came from the 2 engine prices on the invoice and the window sticker and that may have been normal but I have not found anyone who knows

[spankmaster]

o ok Yeah I wasn't sure of your ? just thought I would throw that out there. Can't answer about the window sticker sorry.

A couple of questions? are you sure you have an "s" as the fourth number/letter in the VIN? (this is what really counts)
The base engine for a 67 GT (GT requires a V8) is the 289 with the 390 optional which may explain the window sticker. GTA indicates GT automatic and is generally a 390 but not necessarlly a 390. (yes there are 289 GT's and GTA's)
The GTA badge is avalible from most any Mustang supplier. All 390mustangs came with 9 inch rear ends. 289/302 Mustangs have the 8 inch rear end.
A 428 and a 390 are identical in appearence and size from the outside impossible to tell the difference without measuring bore and stroke, therefore can be used in place of each other with no one the wiser. There are a number of 428's masqurading as 390's out there. Geniune 67 390 GT heads (also found on Fairlanes and Comets) have 14 bolt holes for the exhuast manifolds. These are the ONLY heads with 14 bolt holes. CJ heads have 16. ALL others have 8.
I once owned a 67 coupe with a 390 ("s" code in the VIN, C6 automatic) which had 289 engine badges installed by the factory and was planing on making it a 428 but went and bought A 69 Cobra Jet instead. The 67 was a fun car because everyone thought it was a 289. It was not a GT, not all 390's were GT's.
If you do indeed have a 428 instead of the 390 then that car is not original
If the car needs to be at that level of detail then you would have to put a 390 block in there. A 390 block is easy to get. A 428 is much more difficult to get. The bore of a 390 is 4.05, the 428 is 4.13. The crank will interchange but a 428 block cannot be made into a 390.
There were some 67's with 428's but these were all Shelby GT 500's code 4 in the VIN.:)
Hope this helps! :wave:

Thanks yes it is a S code car i put the vin some where back aways in this mess yes it has the 14 bolt heads and yes I am sure it is 428 as we built the engine checked the stroke and the bore which was standard at 4.13 we found all this after buying the parts and sending them to the machine shop. the machinest told me something about the block being one that did not come in any car I didn't listen at the time but I sure wish I had now. The car is currently at the paint shop but when it comes back I am going looking for casting #' ect. I knew the dealership had played with somethings as it has a aluminum sidewider intake with ford #s and also a 4300 carb which I don't think was around in 67 I also have the 100 lb intake with the S on it which was in the trunk by the invoice and widow sticker it is a GT package with all the disk brake and pwr. stg. and a/c options also the full length console no rust so it is a pretty neat car no matter what the engine is I an just thrown by the 2 engine charges on both the window sticker and the factory truck invoice thanks for all the info Tony

I think the 4300 carb came out in 70 or 71. Its pretty common on 351 Cleveland motors(like I now have) in 70-73.
Not sure but I think the sidewider intake is from 68 or 69 only as an over-the-counter part.
The base motor for a 67 mustang was the 200 inch 6. The gt required a V8 so the 289 charge may have been automaticly added and the 390 was the opitional engine charge. Although one would think the 390 cost would not have to be added to to the 289 but to the base cost,

Quality in 1967 was no where near as good or important as today!

It will still be a fun car. I really liked the one I had!

[500575]

Yeah me to this thing is awsome about torque with the 3.00 open rear end and the 245 55 17 tires it had when I got it you could almost not start without liting the right rear I have now changed the cab to a Bill Mitichel special (built Holley from a 415 SBC) so I' m looking forward to geing it back from the pait shop to see what it is like now.

Yeah what I am trying to find out now is if this is one of the " warrenty mistake " deals that Ford dealers sometimes did as in blown bottom end accendetially ordered 428 service shot block o well put it in it is cheaper than all the paper work and shipping. I am getting some feed back that says this could have been what happened as the original owner also held a finacial interest in the dealer ship. If this is just a deal like that does anyone know if a 460 or a 429 SCJ will fit in 67. Thanks again Tony

[500575]

I am hearing stories of 390 etc getting 428 short blocks or complete motors under warranty by accident. If someone knows somebody in the service department they "blow an engine" and the service manager "accidentally" orders the wrong part number and gets a 428 when it was supposed to be a 390. Then it's "too much trouble to send it back because the shipping would be more than the cost difference. So it's just installed in the car. Of course, the customer knows about this if he happens to be friends with the right people. I wonder if this could have happened to mine because I'm finding out that the original owner of mine had a financial interest in the dealership where it was bought and was well known to be a street racer. If that's the case, it really doesn't make this car any more than a 390 with a 428 bore and stroke. If this is true, does anyone know if a 429 or a 460 SCJ will fit in a 67 Mustang?

Thanks for any info.

Wow never heard of that interesting though. Must be nice to know people.

Yes 429/460 will fit. There are headers(FPA) made for the swap. One needs to make sure of the clearence at the front of the engine to the radaitor. You will need a short water pump,custom radiator,fan etc. $$$

However, you could put some Edelbrock heads (about $1200) on it and a good cam and you would have a Cobra Jet.
