Default 1966 I6 200 to V8 conversion cost?

I'm hoping to convert my 1966 I6 200 to a V8. What should I expect to spend for this? I'm really interested in a weekend cruiser with just a bit more pick-up. Not a racer. I see good crate engines for about $3,000. Some used engines of unknown quality and perhaps incomplete starting as low as $500. But what would it cost to have someone do the work? I know there is a longish list of other parts too. Suggestions? Getting a doner V8 was suggested but I'm afraid I'd be stuck with the shell afterward.

It would probably be better to sell your I6 mustang and then just go buy one with V8.

just off the top of my head, you need: radiator, springs all 4 corners, rear axle, wheels (4), tie rod ends, throttle linkage, bell housing, engine, brakes, engine mounts, badging, probably more (spindles?). while it's all blown apart you mind as well replace the trans mount, shocks, any suspension pieces that are worn out, upgrade to disc brakes, add an export brace and mote carlo bar.

pre-67 are the most expensive to convert. it's definitely cheaper to buy another car or a donor car and sell what's left. as for labor, probably in the $2000 range.

Buy a parts car. I bought one for $400, took off everything I wanted (as a bonus, mine had brand new seats and such), and sold the hulk for $350ish (can't remember exactly).

Maybe I got off so cheap because I already had my engine and transmission on a stand. The guy that bought it wanted the 289, but it was pretty toasted. I'm pretty sure I got the better end of that deal.

This is exactly right. It's a lotta work, changing over the engine, trans, cooling system, electrical system, exhaust system, front steering and brakes, driveshaft, rear axle and brakes, and some other stuff. Plus when you sold it the buyer would kill you on the price because it has an I6 VIN.

Why do you want to change over? You could put headers, dual exhaust and aluminum wheels on your I6 for a fraction of the work and cost, and it would look and sound like a V8 car. Of course, it would get way better mileage than a V8 car…

I have a 65 that I converted to from an I6 to a V8. I would do it again. It is some work, but since the car is not a daily driver we just worked on it when we had time.

I don't agree that a buyer would kill you on the price for a converted car that had an I6 VIN. The I6 cars are not really worth all that much to begin with unless they are convertible or maybe fastback.

As far as milage goes. My car was a daily driver for a few years and got about 16-18 mpg. Now it gets about 16-17. So, the milage really isn't any different. Of course I have a T5 now.

Also, It doesn't matter what exaust you put on a 200 it will sound like a 200 not a V8.

If you want to tackle the project then I say do it. If you are happy with your car and really just want a bit more pep, the you should probably stay with the I6. You could always swap out the 200 for a 250.

The cost of the conversion could be anywhere between 2k-10k depending on what you do.

You could also find a wrecked 5.0 Mustang from 87-93 and take the drivetrain out of it and swap it over to your classic. Then you would have EFI and an AOD or T5 transmission with overdrive.

What I mean is, a guy buying a car will balk at paying V8 prices for a converted car with 6 cylinder VIN.

As far as mileage goes. My car was a daily driver for a few years and got about 16-18 mpg. Now it gets about 16-17. So, the mileage really isn't any different. Of course I have a T5 now.
Strange, I had a couple of 66 Sprints, and the auto convertible got 20-25, and the manual coupe got a few better than that.

Also, It doesn't matter what exhaust you put on a 200 it will sound like a 200 not a V8.
Wanna bet? Dual headers and GT dual exhaust sounds like a stock 289 GT, maybe a little better.

If you want to tackle the project then I say do it. If you are happy with your car and really just want a bit more pep, the you should probably stay with the I6. You could always swap out the 200 for a 250.
The 250 uses the same bellhousing as the 302 V8, so you'll still have to change the trans, minimum.

If you want to do the v8 swap to be different!, consider keeping the I6 with a turbo there is a lot of info on fordsix.com, i have a I6 that I'm going to megasquirt. What ever you do have fun with your project.

I'm going to convert my 67 over to a 300 I6 when I get the funds. I can hook up a T5 to it. Only problem is you will have hood clearance issues. I already have 5 lug and an 8" rear end. Just need the engine, 4bbl carb, 4 bbl intake, exhaust, engine mounts, tranny mount, and V8 driveshaft.

A thrifty person can do it cheap, and then a person can spend a lot...

It might be cheaper to sell the 6 and buy an 8,,,,

But on the other hand,,,,

If a person is going to end up updating suspension, springs, engine, transmission, brakes, etc,,,,, ANYWAY...

Like a VERY LARGE PERCENTAGE of Classic Mustang owners on this forum HAVE DONE....

Then it really ain't any cheaper to start with an 8.....

In SOME CASES, it might actually be cheaper to start with a nice clean I-6 car....


"Variables" can and do make a difference...


Often, at best, "one size fits all" answers are incomplete,,,, and at worst they just suck...

I have about $1,100 in my conversion. As JMD says, you can spend a lot or you can spend a little, kinda depends on if you use your head.

I also agree with JMD that it is often cheaper to convert an I6 car than to buy a 289 car.

Here's a rough list of my current project:

V8 Mustang? Anything within several hours was stupidly priced.

I6 - 3 hour one way drive and it's in my shop for $1700 complete with Granada spindles and calipers in the trunk. Rear quarters and front floor were shot, but I coulda put a sticker on it and drove it. http://advancedautorepairsonline.com...and%20more.htm It's a good bit beyond these pics but due to a computer crash killing tons of data I still have a ton of work to do before bothering with web page updating.

Donor car with roller cam 302 and AOD $500 with a car left over afterwards. An intake and cam will be about $500 new. I haven't shopped yet. I can do better once I put the time in. Carb and heads still to be determined but expect $1000-1500 for good heads. I could stop at the $500 donor cost and use all the parts as-is plus an inline fuel pump and odds-n-ends. Nahhhh...

9" rear end still unavailable at a decent price so I'm looking to probably shorten an Exploder 8.8 for about $300 all said and done with disc brakes and a locker. I can live with that .

Front coil springs were either $60 a pair or apiece. I don't remember... I've already done the Shelby drop - not because I want it lowered. I want the handling. It was free.

I'm really expecting this to run around $6k-7k all said and done. That includes the car, paint, a/c, tires, wheels, quarters...

I'm doing everything myself. My build expense is parts only. Total value for me to sell it? $642,386,214.53 and that's cash only, not negotiable. How much each project costs relies entirely on a person's ability to be patient, lucky and shopping skills.

i've done the whole lot myself, but I spent a fortune on parts. bought about everything new. all brakes, rear axle, diff, transmission (rebuilt), etc etc etc.
I had to go this route as I had to ship the parts from the states and needed to make sure it is good stuff (no point in shipping half ton of parts that are rubbish). but saved a fortune again in doing it all by myself (and friends).
I have at least 100hours in it and quite a few upsets ;-) so unless you are doing it yourself and go cheap with 2nd-hand parts you really might be better off buying a V8 car instead of spending 2 grand on labour

in my experience what you buy is always cheaper than what the owner has put money in it. if someone buys a car for ten and spends another 10 on parts it'll always sell for under 20 (unless he made an unreal bargain somewhere)

Some people may not be to interested in paying higher V8 prices for an I6 VIN car is probably right, but alot of buyers may not even look at that.

I have heard 200s with all different kinds of exhaust and none of them sounded like a V8. I wasn't saying they sounded bad though.

Yours does really sound good but I can still tell that its a 6 cylinder. It sounds better than mine did when it was still a 200.

At one point in time mine had a transverse mounted Firebird style muffler on it to get the dual exhaust look I wanted. At idle it did sound good and close to a stock V8. It sounded ok at lower to mid rpms but as soon as the rpms went up you could tell it was a 6 banger.

I'm not sure how yours got that kind of miliage. I had a few friends with 65-68 I6 Mustangs and none of them got better than high teens for mileage. A few other friends had 289 and 302 and most of the got about 12-15 mpg. None of these cars had an upgraded overdrive transmission. Wonder what kind of mpg a good running tuned up 200 would get with a T5?

Frankly we spent a lot,,, but we would have upgraded everything we ended up changing out anyway... so we could have paid more for a v-8 that needed more work and ended up spending even more...

We did not build the car as an investment. And even with what we did spend we could not have bought a new car as nice for the $$...

If we had bought a new car instead, we would have lost a third of the value when we drove it off the lot.....

Hmm... the 66 certainly was not an investment,,,, but still, we are a LOT better off now than if we had dumped the same money into a new car. This imaginary new car would now be worth even less than the coupe we built...

Just depends on how a person looks at things...

Who has a car that they bought new that is now worth as much as it cost?

I don't think we will get MANY credible POSITIVE answers here....

Man I would never want to convert my 200 to a 289. If I really ever wanted a 289, I'd do what stangtjk said and sell it and get one with a V8. And that also is probably a never.

Oh and by the way, the I6 200 sounds really great with 30 year old cherry bombs. Honestly, it sounds nothing like the v6 or 4-cylinder fart-cars of today and thats what matters to me.
