Default 1966 Mustang 6 Cylinder to V8 Conversion

What exactly will I need and does anyone have detailed instructions on how exactly to do it? I know I need a new bellhousing for the C4, flex plate, and converter, and rear end. What do I need as far as suspension goes?

I am in the same boat. I am building a 67 this summer and need to know about the motor/tranny mount info.

I heard another owner getting advice and they were told that changing the engine also means changing the suspension, and maybe the wheels as none of your original stuff will work. He literally said that you would be building a new car by changing the power plant.

You are obviously more experienced than I, but I thought I would add that in the thread for the less experienced readers who might think that its a drop it in and turn the key operation.

ok i did this swap in my 65 i assume your getting the bellhousing and bigger rear, the driveshaft is exactly the same from the v8 and IL6 i matched them both what suspension is tricky but not replacing it totally all you need is larger v8 front spindles which are very hard to find unless you have a donor car fortunately for me and you will need a different steering linkage with bigger tie rod ends and idler arm, as far as your upper and lower control arms they are the same and as long as your front springs arent worn they'll take the load of the v8 it just sits a little lower in the front, i like the stance it gave my car but its up to you if you want to replace those or not, other that that you just need 289 engine mounts and you should be set, i did a 200 6cyl to 289 swap with a c4 so if you need any more info let me know

also one more thing you'll need a different radiator, get the one for the 289 it bolts directly up in the old mountinf position but the in and out ports on the 6cyl are on opposite sides of the radiator, and the ports for the v8 need to be on the same side just figuered let you know to add that in to your priceing plan

As far as I know, the engine sawp is pretty much a suspension and rear end swap, and not much more.

I did this swap on my 66 mustang. You to replace front-end suspension, brakes, steering. Also rear-end and springs. Also engine mounts and radiator. I found a wreaked 65 ranchero that the frame was bent and picked it up for $1000 bucks.
I also went from and automatic to a four-speed, like more work but all came together. And runs like a dream now, so there is light at the end of the tunnel.

You will have to change the entire steering linkage, the motor mounts, rearend, springs, and radiator. I also recommend changing the brakes. You will also definitly have to change the spindles, which will be the hard part to locate. If you can't find a V8 donor car, you can use the spindles from a 67-68 Mustang or 69-73 Mustang. With the 69-73 spindles they are beefier and you will have to use bigger bearings. With all the spindles you use you will have to use the brakes and oouter tie rod ends from that year. Just remember that the 67-68 spindles have a disc brake spindle and a drum brake spindle. If you use a drum brake spindle then you will need a disc brake conversion kit, if you use a disc spindle you can just use stock parts. The 69-73 spindles are the same for disc and drum brakes. I used the 67 spindles on my 66. But whatever spindle you use DO NOT use the original 6 cyl. spindle. IT WILL BREAK, they would often break with the weigh of the 6 cyl. if you put a V8 in it there is no way it will support the weight.

I'm just a rookie myself, but I've seen this thread started at least once every other week. If you do a quick search of the forum using the search function up above, you will find several threads on this exact topic already discussed. I'm sure you'll find the answers to all your questions. Good luck with the swap!

Do not forget that you need to use a 289 timing chain cover. That also includes the water pump and alternator. I just got done doing the conversion and it was well worth it. Don't forget you will need adapters for the engine mounts to work. And new cross member for your transmission. I think I have lerned the hard way for the whole conversion so hit me up if you get stuck.

The C4 transmission for the V8 has more clutch discs and steels that go between the clutch discs. I believe it is two more of each. This update can be done to the C4 for the 6 cyl. A rebuild kit for the V8 trans would contain these extra parts. If you don't do the update the trans will cause you problems eventually. ---Chuck

Just my opinion. Its about all rides too, not only Mustangs. if you want something with a V8...sell your V6 and buy a ride that was born with a V8. Some of the projects i have seen, they just wernt the same afterwards. never did run/drive well.

for later model cars I would agree but with our early mustangs It just depends on whether you want to do it cheap or right. when I built my 65 I replaced all the parts I would have had to replace to convert it from a 6 to a v-8 except the spindles (since it was a v-8 car) and I did that just in the name of improving handling and performance. the body on these cars are exactly the same. the only time you are going to run into these issues is when you try to cheap out on it and not do it right. on any car I build to drive I don't care what it is I am going to have disc brakes and power rack and pinion steering upgraded sway bar and 620 springs. if I bought a v-8 car I would do that same with a 6 to convert car. I swap a 9 inch in to make sure It can handle anything I throw at it. spring and handling kit. and a new wiring harness. then its basically just an engine and tranny swap. so again. there is a lot involved but most of the stuff will get done when restoring a 40 some odd year old car anyway its more a matter of replacing the stock parts with upgraded v-8 parts than with stock 6 cylinder parts. and you have to do it all to make it work right rather than a little at a time. unless you do the suspension first and the engine swap last.
