Well-known member
So ive looked and looked for a 250 engine and i cant find one in my state and all the ones on ebay wont ship...so my question is would it be possible to work a v8 on my 65 6cylinder suspension and rearend?

It would be possible to bolt a V8 in but not safe. The I6 suspension is not designed to handle the added weight and power of the 8 :cry: As for the rearend, it will not last long. Why not hop up the 200 :?:
 
Definitely ill advised to put a V-8 into a 6 cylinder car without doing the rest of the conversion such as:

1) Radiator
2) Suspension
3) Front end (5 lug)
4) Rear end
5) Transmission
6) Ignition

Just to name a few of the systems.

Now, consider the recent 200 news. Mike's Aluminum head, with cam and headers just put down 220RWHP. To put that in perspective...a stock 65 289 4V (non-hipo) only puts down around 150RWHP. Total cost for Mike's head/cam/headers would probably be less then a V-8 swap would costs, even if you are luck with donor parts. Downside...you'd still probably need a rear end upgrade with the HP. My only 4 lug rear end didn't last long once I hit the 150RWHP mark.

Don't give up on the 200. It has advantages over the 250. Sure, it's less cubes, but it revs better and gets better mileage generally (and that is generally good these days). Even a 250 would require some modifications to an early mustang to make it fit. It's a little taller then the 200 and would require custom engine mounts. A large cowl hood may fit the 250 without engine mounts, but I"m not sure on that.

Heck, I'm only an engine away from a V-8 now. Suspension, tranny,steering, rear end, front end...pretty much everything is set for a V-8...but for a daily driver I do love my 25 MPG on back road driving.
 
IMO the whole suspension brakes rearend thing has nothing to do with the car being a V8, I6 or Cummins Diesel.

If you put a heavier engine in the car, it is a good idea to upgrade the suspension or else your handling may become unsafe. Also, some of the lighter duty components may fail.

Also, if you put a sufficiently more powerful engine in the car (V8 or hopped up 6) parts of the drivetrain will break.

There is nothing inherent about the # of cylinders that dictates what youneed to do. Its the load (weight) on the suspension and the load (power) on the drivetrain.
 
Thats what i thought...yea i have posted and posted trying to find a 250 but cant anywhere close by...my 200 has a crack in the head so i would have to get a new one and then go to a engine shop to make sure the head and block fit properly and get them milled...and i dont have the funds to go all out on aussi heads or alum heads...so my original thought was to just go for a complete 250 but that is turning out impossible i have my 200 block and it needs a head and a rebuild im sure...the other thing i wanted was a actual toploader 4spd can that be modified to the 200 i havent looked that up yet...the lightduty i have on the 200 i always hear is a waste of time and i think it is...so that was my decision to switch to the 250..
 
You do know that a 250 head well work on the 200.. so you might be able to find just a head and have it gone throu... it would have a bigger log and carb opening..

the 250 isn't much lighter than a V8. i'd keep looking for a 200. check with a local mustang club. someone might have one sitting their garage. 8)

... i have my 200 block and it needs a head

You can have my 200 head for $5(I need to buy boxes) and cost of shipping. I need to start getting rid of stuff. Where are you by the way? PM me if you want the head.
 
I'm here in Klamath Falls Oregon, if you need parts, I have a few contacts that are here and in the Rogue valley.

If you need a rebuilder core, I have a 68 long block that had a leaky headgasket. ran great but I had the other motor done when it started leaking... made the choice to swap easy...

PM me if interested.

BTW, if you add your location to your profile, we can see where you are located
 
So im sticking with my 200 then...im currently getting the cracked head off of the block... clean up the block and then find a rebuild kit...then have to figure out what transmission to put on.

Who is mike and where do I get information on these upgrades you mention.
 
Oh and to answer your question if the 200 is a 66 or later big bell then yes a toploader can fit and has bellhousings all over the place. Just get one from a 3.03, its the toploader bell housing :).

Sorry, I don't tend to check post counts so didn't realize you may not know. Bort62 is correct. He is the sponser of FSP and the owner of classicinlines.com. He has probably been one of the biggest forces in the ford inline 6 performance market since Jack Clifford actually cared about it.

Bort, I agree with you. I don't equate the list of parts to change out based on weight. It has to do with performance like you said. Some have to be changed out (like the radiator)due to arrangement, and others should be change out for safety (like brakes) and still others for reliability (like the rear end to handle the power). It was for all of those reasons my 6 cylinder has so many "v-8" parts. I got more power, which killed my original rear end, so I upgraded the rear end and tranmission to handle the power. The brakes were upgraded for safety with a daily driver.
 
Yeah im sure ill do some major upgrades later down the road...but im going to stick with the 200...its a 65 so its not a big bell...thanks for the feedback its once again put me on the right track to stick with the six.
