If you were lucky enough to be able to buy a (replica) Shelby Cobra, you would have a

lot of options for power. What engine would you choose, and why?

That. The Coyote 5.0. Nothing else!

Just for the fun of it I'll say a Viper V10. It was meant to be a Cobra revival, after all.

Easiest decision in the world either an aluminum block 427 with a set of weber IDAs

or a cammer

3-cylinder ecoboost, just to mess with people. It'd still be powerful enough to have fun.

Pratt & Whitney Wasp Major. Because tube frames mean never having to say you're sorry, because no replacement for MORE DISPLACEMENT THAN A BALEEN WHALE, and because fuck practicality right in the eyesockets, that's why.

More seriously, perhaps a scaled down replica of a Napier W12 in aluminum with triple supers, because Ws are just cool as hell.

The 12000 RPM Cosworth DFV 3l ITB DOHC 500HP V8, mounted to the Chassis a la old-school F1.

You could turn the Cobra into a front-engined, closed-wheel car with the drivetrain of an F1 car.

Didn't really think that. Here in Brazil "Cobra" is the same as "snake".

My bad.

Still, that Renault Logan Cobra looks sick.

Apparently they made so many DFVs (over so long) and they were so reliable, that at any given point there's a few of them for sale in vintage motorsport. The rock-solid reliability and unique (and since never repeated) performance characteristics means you can pick up new or rebuilt ones for around $30,000-$50,000. They're a bit much for a weekend car, but a track-only Cobra could actually seriously benefit from it.

Plus, they only weighed about 350 lbs, half what the 427 weighs, with more power.

That's pretty cheap for what you get, especially if you compare it to what a contemporary crate motor costs.

It has been said to produce 850-900HP unrestricted. Can't cite a specific source, but I'm pretty sure those are the general numbers.

The new Turbo EcoBoost. Good enough for a full-size truck, good enough for this. And easily worked on at a Ford dealership.

289, the better of the OEM. This car can't handle a 427, and neither can your drivers license.

Pratt and Whitney 127TS. Because 3000 horsepower, it only weighs about 1000 pounds, wet. Dimensions are 32*27*64 inches, would it fit? That power number is at 20k RPM, but it's a turbo-shaft engine, so it's designed to actually drive something rotationally. A quick lookup shows the standard cobra weigh's around 2300 lbs, so assuming 500 for engine and transmission and such, 1800 lbs, add 1000 to 2800 for 127TS, throw in a truck transmission at around 400 lbs, to 3200. Very very rough power to weight ratio of about 1.07, for note, a 2005 F1 car was getting in the 1.43 range (lower is better). It wouldn't be balanced, and it's tires would lose traction if you even thought about going faster, but man... I wish we had jet engines in cars...

I really like the idea of the 3 cylinder eco boost engines.

http://jalopnik.com/5961187/ford-b…

Someone on Oppo or the fp a while back had the genius idea of mating two of these together to form an inline six. Twin turbo straight six in one of these could be wild!

Koenigsegg CCX' 4.7 litre twin supercharged V8 producing 806 PS at 7k rpm, and 920 Nm. I think its angry character would fit the car beautifully.

Because it is the wrong answer and heresy, not even the sweet soul worthy kind. Stick to leaving the LS in a 240z-280z.

I'd put either a tuned 4.0l Jaguar AJ16 I6, or an S54B32 from an E46 . I'd make a replica AC Ace.

Everyone puts V8s in kitcobras.

You could put about 400lbs of Tungsten in the trunk to balance the car better, and the power/weight ratio wouldn't suffer *too* much.

Go with a Ford though, a 572 Chevy would be blasphemous.

I have heard of some insane 5" to 5.25" bore engines (usually on custom 5.5" bore spacing blocks) pushing nearly 12 liters though. They're rare, but out there.

FireAway3 > zadtheinhaler 10/11/2013 at 19:41

Meh, I would rather just build a car around this engine. If you wanted to really make it complicated/awesome, you could have the engine run an electric generator and use electric propulsion, a la that recent Jaguar concept. Have the intakes be at the bottom of the car and the exhaust backwards and slightly up too, ground effects...
