1967 Fastback 'S' code

[mm8891]

I found a 390 out of a '74 pickup, along with a C6. Would I be able to install these without any issues? I also need to find a driveshaft and a 9' rear end but those can come later.

Any input?

[mm8891]

Anyone?

Hey, I think I might one of the few here that has an S code. I'm not an expert mechanic, but I don't think you would have any probs getting that engine and tranny in the car. I'm assuming the only issue might be the wiring. As far as drive shaft and diff go, that's a another story. But so many of these parts are compatible that you shouldn't have a hard time finding them of another vehicle. Try and find a local mustang club in your area or some type of muscle shop/mechanics so you can find out what old vehicle to look for. There are a lot of parts out there for our mustangs. Good luck and I'll ask around about your question. I got a friend that has 3 s codes at home.

Thanks, I'd really appreciate that!

I'm just stuck on whether I should go with a 390, or a 351W. 351W would be a tad better on gas, and seeing as I'll be so excited and make this a daily driver for a while that may be the best option.. I'm finding 390's for less money compared to the 351

Look, I've been waiting 15 yrs to get my mustang. Let alone a big block. I think it's the best thing I did, there's nothing like a 390 and the sound of some flowmaster super44's. It's just a different feeling. I've had 3 other mustangs when I was younger, one had a 4.6 and the others 5.0's. Great cars but I've always wanted a big block and your right that parts and the engines are easy to find.+++ cheap. If you have an S code car......buy a 390 ! With a good setup: intake, headers and some nice gears you'll never regret it. My car is a BLAST to drive. Talk soon..

Keep in mind that putting an FE motor into a 67 is a very tight fit. A 390 is nice motor don't get me wrong. I got a high performance 390/C6 320 HP combo that came out of a Grand Torino. With a good intake, head work and LT headers it'll make 400 horse easy. If it was me, I would go with a built small block. Just my thoughts.

390 all the way

[mm8891]

I found just a 351W for 1,400.

390 + C6 I found for 1,000.

How hard would it be trying to change out spark plugs, change oil, and the like?

Being in Arizona I might be looking into a/c also

[BigpapaDean]

Its not that bad to work on the engine. The only thing that's tight is around the manifold area a little, so when your getting ready to decide what type of headers you're using just don't change your mind after. Lol....anyways, don't worry about it. There are so many after market companies making ac units that it won't be hard to find something. It's easy as pie my friend!

[mm8891]

If I decide long tube headers, would that make the work area more of an issue?

No matter what type of header you go with, it's going to be tight around the exhaust. Nothing you can really do about that. Getting to the plugs is not impossible, just difficult. Gonna need some universals and an afternoon to change plugs. The car was just not meant to have a big block in it. Even the 68-69s which came with big blocks are tight around the shock towers. It is what it is.

You could always drop about $2500 into the car, remove shock towers and changeout the front suspension to the mustang II front end.....

[mm8891]

I was thinking of playing around with the engine compartment like that but I'm afraid of it hurting the value of the car since it's an S code.

Haven't had a rare classic like this before

[BigpapaDean]

I wouldn't start going crazy and modifying the s code too much either. I'm keeping mine nice and simple and as close as possible to my marti report. Maybe one day get it back to its original color. The only time I would start adding all those modern upgrades is if the car was an other code less valuable and even do something restomod. But for now I wouldn't touch yours, keep her as original as you can. It will pay off at the end. Have you decoded the car and have you pulled the marti report on her yet?

[mm8891]

The car came with a marti report haha

[BigpapaDean]

Nice!! So? What's the scoop on the marti?

[mm8891]

There it is!

[BigpapaDean]

Buddy...very good report. I would not change too many things on that fastback. It's worth good money if kept the way it was made. I got drums all around on minr and I won't even bother putting on power discs or anything, just because I want to keep the vehicle as pure as possible. I would do the same for yours. Even more so. You have a nice report with good options. These S codes are rare. Let's try and keep it that way. Just my opinion. I'll show you my report soon.

+1 Bigpappa

[mm8891]

There's already power brakes in the front but that couldn't be helped. From what I heard the original owner put them on later

[BigpapaDean]

Look it's all good to have some updated stuff on the car, I have the center console and fold down seats that the previous owner put on. I'll leave then on for now and one day when I redo the car completely ( rotisserie ) I'll put it back to the way it was.

[mm8891]

I'm looking to do something like that. Just make the car practical but not do any radical changes that can't be easily undone

[BigpapaDean]

Same here, a couple of yrs ago I almost bought a 66 fastback with a 408 ( 600hp) machine! The old man was asking around 26000$ and I brought him down to 16000$ just because the car was too radical and too fast. Goes to show you. I guess it's all good, as long as you're improving the vehicle. But you do too much and you slim down your target buyer if you wanna sell one day....god forbid. Lol.

[mm8891]

Hopefully one day people will get to the point where they don't care because it's so difficult to buy one. Being a young guy, I may live to see that day!
