Answer 1

With the recent craze of resto-modding 60's mustangs, I'd look at a 302 or some variant of it. (306,331,347 strokers) Depends on how wild you want to get with it. There are several companies that make all the parts you'll need to put a fox body Mustang (79-93) drivetrain in the car with minimal changes. There are a ton of companies that make 302 blocks and a ton of donor cars out there if you want to pull a junk yard motor. It would probably be the most economic way to go, plus there is a tone of aftermarket parts for the motor. I'd stay away from big blocks becuase you lose all the engine compartment room that makes the older cars easy to work on.

Answer 2

67 Mustangs are not too rare depending on the motor it already has and the body style, fastbacks look great restored or in hot rod form. If its already a big block car then keep it a big block. Meaning 390, 427 engine, those are pretty rare. The bigger the motor the bigger the price. A 428 SCJ would fit nicely but would cost a bundle.

Truth is its your car and I'm tired of boring restored mustangs, they are a dime a dozen. If you are going to do it do it right. I do like stock exteriors and mostly stock interiors then brakes, suspension & engine who cares just keep it all Ford.

Engines that will fit your 67, 289, 302, 351Windsor, 390 which also includes 410 mercury motor 427, 428SCJ. These will all bolt in to your existing chassis. I would go with a 302 or 351 which are the same block as the 289 and same bolt in. You can use a C4 or stock trans with those. The 302 with 351 heads would work fine and also you can dress this motor up with stock 289 valve covers and air cleaner so all those purists would never know. Shorty headers are the best since you won't have to worry about ground clearance and some will bolt up to the stock exhaust.

I keep forgetting the 5.0 HO motor from that was used in a lot of Fords especially Mustangs from 1980 on up is the old style 302, this is a direct bolt in for your car also. A lot of them around and a good motor in the 5.0 series. Lots of power right out of the box.

If you have an original 289 take it and have it bored out to 302 and use the cam and crank for a 302, do some head work or get a set of 302 heads. You can still dress it up to look like the original motor. My 64 Galaxie has a 1970 390 in it but is dressed up to look like a 1964 390, most don't know unless I tell them what year it is, I even used a stock 64 intake and carb.

Also if you had a 6 cylinder you will need a better suspension and brakes, most 6 cylinder Stangs that year have 4 bolt wheels not 5 as a 8 cylinder car. So the bigger the motor the more brakes and cooling system you will need and the more upgrades.

Theres a lot you can do and a lot of parts available, call Mustang Country or other Stang resto houses they will help you. Just do it right and make it look good. Don't cut the body up though or throw away original parts in case you want to restore back to stock or sell them to a purist.

Answer 3

Iam building up a 66 and had simular questions, I ended up going with a 347 stroker motor. built by smeding performance..its really a 302 block stroked to a 347. As far as the headers go heddman shorties are a good choice because they allow for clearence on the power steering side.They also have a heat dispersing coating that will help keep your engine compartment cooler. Intakes are a no brainer Edlebrock Victor jr. single plane is the way to go..And exhaust, flowmasters are always a good choice.. they just came out with a 44.. its really the 40 with a little more volume..Dont forget the electrical, MSD is what i chose but Petronix is also very good....

Answer 4

a 302 would be a good choice, headers, cam, Holly manifold and carb. buy some Mustang magazines and check out the engine articles and advertisements.

don't listen to guys like Gerald who think all Mustangs should be stock, Mustangs are for fun, you won't ruin it by modifying it, make it the way you want and enjoy it!

added: your lucky it's a 67, that was the year they widened the engine bay to fit the 390/428, so just about anything will fit. The coupes are a dime a dozen, it's the fastbacks and convertibles that are worth a ton of money.

Here is a good group and there are lot so good links and good info in the archives , so catch up on your reading :)

Answer 5

Purchase a Haynes Manual. Chiltons is good but Haynes Manuals are better because they actually did the work. Base 1967 'stangs came with 6 cylinder engines...V-8 engines from 289 cu in all the way to 427 cu in were cash added options. Check the VIN number. That will tell you what you should have in it. The VIN also tells you the color of paint and interior and the transmission and rearend that came with it.. 1967 Mustangs are worth a lot of money restored to original.

Answer 6

I would put a 347 stroker in it with a good C4 or T-5 tranny. Long tube headers with Flowmaster 40 series mufflers. I would use an Edelbrock RPM Air-Gap intake manifold with a 800 Edelbrock AVS carb.

Answer 7

but the biggest motor that will fit without hacking it up because if you do than it will be worthless. if you have to choose between a 302 and 289 choose 289. they are better on gas milage. but if it has a bigger engine compartment i would put a 428 in it with 3 2 barrels. make it fun to drive!!! i would get tri y headers from ford power train. and i would get flowmasters. holley carbs. and a cast iron intake. but if not get an intake from edelbrock. GOOD LUCK!!!!!!!

Answer 8

Go to summitracing .com, order a brand new .30 over 302 block, order a rotating assembly, summit cam #sum-k3601, Edlbrock heads, a Weiland action plus intake, Headman Hedders, holly 650, chrome engine dress kit, MSD distributor.......this will give you a brand new 350horse or better 302 for $2500-$3500, it will be very simple to build, maintain, very streetable, reliable, good on gas, sound cool........ 289 and 351's are cool but cost way more for parts and not as many parts available, the 302 is the common one and is easy to make power out of still. Good luck!

P.S. Don't listen to guys that say restore to orginal, life is too short for that, make it fast, make it how you want and then you can have storys to tell when your old!

Answer 9

Frankie try the local automotive parts stores and look for the performance,stores too and they will provide answers to all your questions.In engines the 351 is a fine choice for a engine for a ford mustang.

Answer 10

if it were mine id build a 460 stroked to 545 to put in it ;) the 460 will fit if you put a hood scoop on it... its about the same size as a 390 just taller- hence the scoop. www.critesrestoration.com has the swap parts for the 460, and the headers and hood. throw a c-6 transmission behind it and youre good to go :)
