My 68 GT mustang It is a 100% original car (never been restored) but the 390 seized and was replaced.

The outside has the usual rust, nothing serious all repairable.

What would its value be at? I've been offerd 35,000 with no intention of selling but just curious.


The motor replacement is a 351C 2v, I'm wondering what its capable of. The previous owner said it was fully built up.
I've never been through the motor and it has been in awhile.

It idles about 1200 rpm, with a 850 holly carb, and edelbrock intake.
Its got a 4 speed in it, with a hurst supershifter kit w/e installed.
I was told it was putting out around 400 at the rear wheels,

but is it possible with this motor?

Would this motor be worth keeping and useing, or find another 390 and performance that out?

The fastback is full GT all the luxaries with 4.11 limitslip rear
This car may be all original but in the future its going to be a high performance restoration for me and my dad.

I hope someone can answer my questions :)

The 68 Fastbacks are currently experiencing a high demand. Actually, that goes for all the fastbacks. Your car being a real GT only adds to that demand.

Without pics and a detailed walk-around, it is difficult if not impossible to determine value, but in my opinion, 35k is a fair offer. Especially with the non stock motor.

As far as 400 hp at the wheels, it may be true, but power claims often get fudged so don't be surprised if it is not 400.

Finding a 390 would increase its value, but how much is debatable.

What do you want from this car? You mention it will be restored. If you are looking to make money on it, going original is never a bad choice. If you are looking to drive and enjoy it, keep it the way it is in terms of mechanicals, and get the body work done along with a paint job. Then you can enjoy the car for what it is instead of an investment.

My personal choice for my car was to upgrade it with modern components and drive it daily.

Yea, my dad had a 68 GT when they were fresh off the production line, he wrecked it ofcourse and found this 1 about 20 years ago, he daily drove it and got to the condition it is in today, it fires right up, and sounds beastily, my dad told me how when he first got the car he would always run into fox bodies looking to redlight race, and he'd blow them all off every time.

Never known what it would do at a track though, and thats sort of the direction we want to push the car.
Have fun going to car shows in it, take it down the track afew times a month and just a "go fast" way to it.

As a little kid my dad used to do burnouts in second gear with me in the rear seat giggling as the front end lifted off the ground.

So its that, father and son project for being a badass car, its why we didnt sell it.

Thought as a daily driver, its got front disc breaks, power breaks, power steering A/C everything from overhead lights ext from the factory. deluxe interior all original.

Me and my dad just finished the restoration of a 64.5 Mustang and its my daily driver right now, with a 260 v8 all original to it aswell.

We dont know what we plan todo to the car, but we thought of many things from keeping the 351c to getting a 390, porting some nice heads, flat top pistols port and polish ext everything to build a beast with what we already got.

The 68 is just my childhood dream car, and I hope to keep it till my own kids can ride in the back as I smoke some tires.

Only thing I will say is:

Not a single one of these would sell for $35k they are all in the 20-24k range in the current market (and there is no rust on any of them aside from a little bubble forming on the doors of the 65). ohh and the 68 pictures is an s code GT car with a non-stock motor, 4 wheel disc brakes, 5 speed, and a very well done clone job (aka all the right fiberglass, right lights in the back, correct roll bar)

Also you can't say "all original" with a 351c in it or a 4.11 rear gear in it :winks

I agree with Mustang Bradley for the most part. The value of anything is what someone is willing to pay or the market will bear.

Since you can never claim the car as a "numbers matching", with the original 390long gone, putting another 390 back in it is a matter of debate as MustangBradley states.

My 68 fastback has a 351C.Why,....... several reasons.
1- I'm somehwhat "old school"
2- I wanted to build good hp with the most naturally aspirated power of a small block using stock block, heads, crank, etc. I never intended to race it but wanted the power just becuase.
3-The suspensions on these cars dont do so great or handle so well with big blocks. Most informed people will tell you thast you will crack or damage the shock towers unless you have reinforcements installed. If you do a suspension upgrade, it makes a difference but its also big bucks and is usually more than just the suspension.

Pound for pound and dollar for dollar, the 351C can make more HP per cubic inch than the 390.

Therefore, I choose the 351C. I absolutly love this motor. What a building block for HP

The guy that wanted the car, fell in love as he put it, at the original factory parts and ext, he was a owner of a local vintage car restoration shop, and he explain to me that he always finds cars needing restoring that have been restored before, and incorrectly.

That starting with factory and ending as close to at that is what he wanted todo, but we refused every one of his offers.

and the 351 was installed by a ford dealership in 70 or 71 I believe, when the owner went to them about the seized 390.
But ofcourse many people have gone through the motor since then, beefing it up.

Should we work with what power we can make from 351c 2v? or look for some 4v heads?
or try buy a 390, port some bigger heads and make some power that way?

Since you have plenty of go with the current motor, why not spend some cash on an upgraded suspension and rack and pinion steering? This will help on the track a lot, since that is what you are thinking about doing. These mods really transform the way the car handles. You won't believe the difference. Trust me. :)

Building up the power train you have now will be the least expensive option IMO since if you switch to a 390 you have to source everything from the between the radiator and the driveshaft. 351c 2v can make plenty of power. Before spending any money you need to accurately assess the power you have now.

Take it to cecil for test and tune and run it down the 1/4 for base line numbers. That will tell you if you have enough power to start. Personally I would start with the suspension, brakes, and chassis strengthening since this can all be done ad hoc on weekend while still leaving you a driving car most of the time (if that is important to you).
