to me the 460 class motor makes the least sense of any of the more popular engines. they are heavy , wide and non original. The FE is top dog in most cobra circles, mostly due to its originality factor and it just looks right in the cobra bay. It too has shortcomings, heavy, expensive, somewhat bulky. I would choose an FE first, then a 351 based second, 302 next and 460 last. this is not to say a 460 is a bad motor, I just do not think it best for a cobra.

How much wider is a 460?
I didn't think there was much difference.
Of course, my frame of reference was mostly Ford trucks.
Plenty of room there....

I guess I could be talked into building an FE, but I want to fully discount the 460 first.

it is not that it is too wide, it is just wider than an FE which is already big. there are plenty of cobra replicas with 460 motors. it sounds like that is what you really want to do, and that is ok, I just think there are better choices.

Yes, please understand I would forsake the 460 without a second thought if there are good reasons for it.

Looking at the prices of engine builds, the FE's always seemed to require so much work or all aftermarket parts and that means $$$$.
I understand the FE is "supposed" to be in a Cobra, I'm just trying to get info.

The 460 would likely be much less expensive to get what I want out of it, I could use old factory heads, block and crank with the typical aftermarket parts for a moderate build up.
But if it presents any difficulties the FE would not, that's what I want to hear about.

Like I said, I know a thing or two about the motors.
It's the car I'm new with.

keep in mind that a cobra weighs from 2200 - 2700 lbs, so having a 700 lb lump in the front will affect handling greatly. A 450 hp 408 weighing 200 lbs less than a 460 makes a lot of sense in these cars and can be done fairly cheaply.

If I had any sense I would just transplant a late model Mustang powertrain in it!

Nah, I'm a big block kinda guy.
I've had lotsa 454's over the years, including one in my current 4x4 Suburban.
I can't make myself stoop to putting a GM powertrain in a Cobra, though it makes alot of sense.

It's gotta be a Ford motor, and I'm torn between the FE that I never really liked for 30 years or a 460 that could be built much cheaper.
I see Ford offers a crate 460 for under $10k list, but no FE at all.


If one would presume to use logic, I'd just go get the wife a new Mustang GT with an automatic.
Factory warranty, dealer support, and I would seldom have to wrench on it.

Believe it or not, SHE would rather have the Cobra as well after seing the prices on the new Shelby, Roush and Saleen stuff, so I have to follow my own little torturous path to Cobra ownership, while still lucky enough to have the blessing of the wife!

I wouldn't buy a Ford crate motor, and I love Ford.

There have been too many people I know that had a problem with their Ford crate motor and Ford make excuses why you roached their motor.

Have someone build a motor for you, and get what you want.

If this is your first Cobra, I suggest a 351W based motor.
