I recently bought a 1967 Hardtop Mustang that I plan on restoring over the next couple years. It has a 200 6cyl that is in not-so-great condition. I need to know If it would be better to rebuild that engine with modern parts and make it full injected, or put the 351c from my 1986 F-250 into it? This car is going to be an everyday driver.
Any help you guys could give in the form of opinions, links, or AD’s, would be greatly appreciated.
1986 f-250 didn't come with a 351c. Did you purchase this truck with a different than stock motor in it or are you confusing the 351w and the 351c?
Lotsa people like to put in v8 motors in their old mustang, just remember to do it, you will need to change out the tranny, the rear end, the 4 lug fronts to 5 lugs to match the new rear's 5 lug axles, and the suspension on the front for higher rate springs.
The 1986 Truck did not come with a 351c so you probably do not have a cleveland motor. It is a 351w or a 351m (not sure on the year for the m motor though). The 351c and 351m will have 8 valve cover bolts, the 302w and 351w will have 6 valve cover bolts if I remember correctly. I can get you more info if you need it but to tired now going nite, nite.
My 65 Fastback has an Inline Six. Many people tell me it would be
more desireable and add value if I drop in a 289. Like you, the added cost
of making the modifications to the suspension, wheels, drivetrain and spindles.
Is it really worth it - No. The Inline Six was one of Ford's "Better Ideas".
With a good tune-up including plugs,wires,cap,rotor - maybe you change out
the ignition, replace the one barrel carb with a two barrel, put a header on and
dual exhaust for added performance.
I currently have the 200 CID one barrel and get 24 mpg!
The 351 your considering can be shoe-horned into the engine
compartment but the car was not designed for that motor - additional work
would be needed to beef up its support including motor mounts, not to mention,
a truck motor is set up differently than one built for a car.
Personally, I say keep the Six and do mild modifications until you get the
performance you are looking for. At the least, tune it up and enjoy the
considerably better Mpg, especially if its going to be your daily driver.
Pancake,
In your case Rudy is correct. The trouble and expense for a daily driver and a hardtop is not adding any real value to the car. Your $ will be better spent repairing the 200cid and fixing up the car.
As for Rudy's car I would have dropped a 302cid and done the disc brake conversion in the blink of an eye. Even though his fastback is originally a 6 cyl car it has more fair market value converted to an 8 cyl (as long as it is done correctly) possibly several thousands of dollars. Hardtops (coupes) such as yours and mine are aleays going to sell for less than convertables and fastbacks.
By the was my very first car (still own it today) is a 68 coupe that originally came with a 200cid six cylinder. I have put almost every size engine in that car (200, 302, 351w, 351c 4bbl) now I think I have decided togo to a 428cid until I can afford a 427cid..............we shall see!!!
If it's not hp you're after then you'll be fine goosing up the 200. I think that if you're going to go to the trouble of having to redo everything just to get a V8 in it you should just start with one. Not trying to rag on your plan (especially if you're doing the work yourself) but it just seems easier to start with a V8 car. I love my 200 in my 66 and I know it's never going to be a speed demon. You can get decent power and good mpg out of them and for a daily driver that's good enough for me!
You'd have something nice and unique if you rebuilt the 6 and added some go-fast goodies from either Clifford Performance Parts or Ford Six. I've seen some beautiful 200's out there with a lot of thought put into them and they are something different. I think they're easier to work on as well.
Just my .02...

Without a doubt, the Inline Six is the most logical choice.
It is a piece of cake to work on and when you consider that
the engine compartment is spacious enough to handle a 289, 302
and a shoe horned 351 well, with gas prices as high as they are,
I love to drive my car, so the decision is simple.
There was a time, when gas was less than a $1.00 a gallon,
much in line with the cost of living.
But based on present day and the rough years ahead,
pinching the pocket book makes more sense (literally) now more than ever.
I'm doing the V8 swap in my 66, putting a 351w in it. It's not all that difficult. Especially in a 67, they came with big blocks in them. The spindles and steering are the same in the 6 and V8, but the springs, trans, and rear have to be changed. If you are building the 6 cylinder for any kind of power you have to change the trans and rear anyway. But on the other hand, for a daily driver to school and work, the 6 cylinder makes more sense. But the V8 is just so much fun.
I don't know about the 67 Mustang, but I do know the 65 -66.
The spindles are not the same on the Inline 6 and V8. If you don't believe me,
PM Veronica. I would trust her opinion - period.
Yeah, the 66 spindles are very different for the 6 and 8 cylinder cars. That's the hardest part, trying to figure out what else you can use if you can't locate V8 spindles. But, on the 67 cars they started using the same spindle for both, the only difference is between the drum and disc. They did use different spindles for those. I'm putting the 67 spindles on my 66, it'll work, as long as I use the 67 outer tie rod ends. If you want zero offset use the disc spindles.
how about engine space? will i have to make alterations to the engine bay to fit the 351c? or how about a new crate 289?

You shouldn't have to make any alterations at all to your engine bay. Like I said before, the big block was an option for these cars, and they built them for with the space. From 66 to 67 the Mustang grew about 2 inches wider. You could but a 390 big block in with no problems.
Rebuild my 200 6cyl or put in a 351c?
