Can you convert a V-6 mustang (64-68) to a V-8?

Answer 1

Sure, get a new engine.

Answer 2

It's not a v6, it'll be either a 170, 200, or possibly a 250 straight six. None of these used the same bell housing as the small block v8. The 67-68 Mustangs will take an FE big block (390, 406, 410, 427, 428) or a 385 series (429,460) without any cutting, but it's a real tight fit.
There are kits to swap both small and big blocks into these cars.

Answer 3

The 64-68 Mustang did not come with a V-6 engine, If you have a factory V-6 keep it!! it is most likely worth 100's of thousands of dollars to a collector.

What they did come with was an in line 6 cylinder engine. It is not that hard to convert to a V-8. You will need to change the motor mounts, and the radiator. You may also need to change the bell housing and torque converter (or clutch assembly) on the transmission.

Answer 4

The six to eight conversion of a Mustang is a serious adventure not suggested for the novice. The six's brakes are inadequate all the way around. The six's rear end is inadequate (note the 4 lug wheels on the six).
The job can be done, but the work and cost is enormous.
You would need to replace so much of the car that it would like building it from the ground up.
I have prepared one for racing long ago and the task was a big one. It was very enjoyable for me, but few other would say so.

Answer 5

yes you can, it depend what kind V8 are you going to use. Because most of them you may have to change the setting of the engine itself. I am not sure if the engine base for the Mustang will be bigger enough or not. I know for Mercury Mystique and Ford Contour either I-4 or 2.5L V6, you can swap in to 3.0L, DOHC with out changing anything. Here is a web that you can check it out and ask, cause I know there are a lot people on that web does some V8 swap on the mustang.

Answer 6

Yes, but there will be far less room under the hood--especially if you manage to shoehorn a big-block v8 into it. It's been done before, and isn't very difficult to accomplish. The nice thing about the classic Mustangs is they have a roomy engine compartment and no computers whatsoever to mess with.

V6 to v8 is a popular conversion for hotrods, and Ford, GM, and Edelbrock all make superb crate engines.

Answer 7

Yeah but you have to change a lot of things, you will prabally need a new diff, and in the front you should upgrade your suspension to handle the extra weight, But yeah it can be done, I have a 65 with a 351 Windsor, that is the biggest block you can fit in the stang without putting a new front clip in like a mustang II clip. To make my headers(hedmans) fit we had to notch out the shock towers and make patch panels to get it to fit, good luck

Answer 8

Yes, you can, a lot of the older mustangs had 289 v-8's to begin with. It would not be that difficult. I read through a lot of the answers you already received and half of these people do not know what they are tallking about. Good luck!

Answer 9

yes, just remember to up-grade the whole drive-line. you mean the L-6
V-8 frame mount&matching motor mount
Rad. ,check your front bushing good time to check on the condition & shocks
steering system tie-rod to tie-rod plus gearbox
degrease the engine bay check the spot weild at the shock tower if you have a friend with a weilder run a bead for extra strenght,lead foot and torque on the frame (uni-body)
tranny type c-4,aod,4-speed,or up-grade to 5speed,6speed. try to get a complete motor&tranny set the tranny tunnel might need a beating in area where it might rub or access for bolts. drive shaft with a 1" play for movement. rear-end V-8 (9") how about one with disc(try looking at 70's rear-end) that be cool right. front disc brake some MUSTANG have Disc set-up 11" need the brake lines to the master cyclinder also grib the master for core and the value block for your set-up.
it's good if possible if you have a V-8 donor car and tranplant things over.

Answer 10

Yes no is a big deal because the chassis fit perfect to V8 or V6, if you want a real conversion put a standard transmission a same time

Answer 11

the only problems are that you must get a bigger fuel pump, tougher tranny, motor mounts, and lots of hours of stress. i've done about 5 conversions from v-6 to v-8 and back. its a simple job soon as you get a hang of it. especially if you have a car with no electronics. the motor will go right in.
