The typical high end aftermarket 385 series head flows over 400cfm on the intake side.
I haven't seen any flow numbers from the Coyote heads, but the most I've ever seen a 4V Modular head flow (after extensive porting) is around 340 cfm.
Now, having said that, flow isn't everything, and even with the best flowing heads, 302 cubic inches can only do so much without forced induction.
I personally just can't get on the Coyote bandwagon. I believe it just happened to show up at a time where a lot of Cobra owners just wanted something different than the standard FE, or stroked Windsor. However, there is no real benefit to it, especially if a lot of horsepower is desired. My caveat to that goes to the Cobra owners in other countries/continents that have very strict emissions/engineering rules, or have limited access to aftermarket engines in general. In that case, I would certainly choose a Coyote or other Ford engine over a GM counterpart.
I was never a OHC guy until I realized the M-3's with less cubes and torque were just about the best and easiest to drive Open track car you could buy. Easily blowing away most of the pushrod Cobras at any track event.
Now that Ford has answered BMW with the Coyote I'm on board.
I may be wrong here but a $6.000 crate Coyote in a Cobra replica is going to be a kick ass track car and when the serious track guys start running them, watch out.
Will they ever be favored by the car show, wax and shine street cruises, never.
$6K 400 HP 430 Lbs this is your best bang for the buck.
Put that in a FFR spec racer and nobody is catching you on the road course.

Admittedly, I've never installed one in a car, but isn't the cost much higher with all the support items that you need to install with the engine....i.e. wiring harnesses, ECM, etc.?
I think that they are also a tight fit in some replicas. I've heard Jay Linke say that the cost to modify the engine bay on a Backdraft to get them to fit isn't cheap....
When you start adding up the different costs, that's where it gets less exciting for me. Also, a lot of guys won't want just 400-450hp, so they have to shell out another couple grand for a supercharger.
Now you are indeed correct about the Spec Racer guys....that's more than enough horsepower for what they need, but they're still looking at the cost of the engine plus support items, which is way more than the typical EFI 302 that these guys run.

But as long as it has a Ford FE or 289 you think it has some birth right to be a real Cobra. Wow that was a rant!! If you have built a kit or replica it is not as Shelby and just have a great time building it and driving it and not get caught up with "is it a 289- 390- 427-428- clevland- windsor- 385-coyote-side oiler -top oiler-460- stroked small block-Chevy-426 Hemi(I had a ride in Artnz with 426 Hemi it was awesome)-Viper V10- or Buick nascar turbo V6or the endless possiblities... Just trying to make this the best thread in 7or 8 years
Thor: pat is correct. The issue is best Ford engine for the $ power wise.
I assure you that the guys here aren't operating under some illusion that just because they put an FE or 289 In there car has birth right to be a real Cobra.
You are missing the entire point of the hobby. The Cobra is the most replicated car in history primarily for it's legendary performance and ease of replication not to mention it's good looks. the hobby is a celebration of the car and it's history and the legendary men at SAI that made it happen. A pride the American "can do" spirit that beat the worlds best. I suspect this has something to do with the fact many want this little car to retain the Ford DNA it started with.
The ease of replication is primarily based on it's Ford powered DNA. Some guys want their car to be a clone of the original and exact as possible. Some just want to keep it in the family by staying Ford powered as long as it produces prodigious Cobra like performance and sound
Your Ferrari and Lambo analogy is off the mark. They are hard to replicate for many reasons and impossible to replicate accurately and just aren't for the most part. They are shunned by the real Ferrari and Lambo owners. There is no one car they are celebrating.
It's not the same. If your a Cobra guy you get it.

You guys hung up on drags as the measure of cobra performance are missing the point completely on what this car was desigbed for. I'll raise your FE with a pinto 1971 Ford Pinto Funny Car
