427 or coyote?

[Large Arbor]

Having a aluminum 427 BB, I must say I am not disappointed. The sound and HP's are simply amazing. Don't know much about the Coyotes, but they never could catch the Roadrunner, thus I would stay with the 427.

I have since sold my last car (big mistake) I want to get started on my next build but have been trying to decide on the motor for two weeks going back-and-forth. I like the reliability of the coyote but I am concerned about resale value. Any thoughts?

Vintage look for me all the way. Just fuel inject a old engine and have the old school look. My 2 cents anyway.

Hello Anthony,

Here is a link to a build where the owner took out the 427 SOHC motor and installed the Coyote in a Kirkham.....Lots of feedback in the thread and very interesting.

Wow, thousands of track miles, new definition of reliability!! He seams to live at high rpms. Low end torque is not a concern for him. Nice article

The Coyote will be a nice, reliable, street performer. It will have impressive performance in the upper rpm range and excellent mileage - if that's important to you.

It will not have the low speed torque of a 400+ inch engine, but it will also not buck and fart in fifth gear with 3.31 gears on the highway.

If you want all the drivability of the Coyote and the instantaneous response to your ever so slight movement of the accelerator you need to put a positive displacement blower (KB or Whipple) on the engine.

In blown format you will easily have 580+ ft/lbs of TQ from a very low rpm all the way to redline - table flat and you have 650 to 680 HP for fun and games. As long as you keep you foot out of it you will see low to middle 20's for mileage depending on your tune.

after thoughts; These engines are not inexpensive to build. For that matter none of the engines we use are inexpensive to build but some find ways to become more expensive than others. A blown version of this engine fits somewhere between a side oiler and a SOHC price-wise, if you do it correctly - something to think about

[madmaxx]

ok lets put some numbers down roush 427 $14,500 no computer needed standard install $2K (includes trans etc). what a coyote cost and what is the adder over 2k for complete install? How much does blower cost? is hood modifications needed? nobody needs 650 hp!!! is it possible to get blown coyote with max 550 hp and 550 ft-lbs torque hitting at 4krpm?

Have you priced a TKO-600 in the last 3 years?

I think things are changing in the cobra market and hobby. I used to think a 427 cobra should have an FE, not a small block. The cobra that was "best" was the one that was the closest to the original that one could afford. Lately I have changed my opinion. This is after building so many cobras I can't quickly add them up. I think the coyote engine is an awesome engine and fits well in a cobra that is built in the spirit of the a 1960's cobra but a new rendition. Backdraft has been the leader in this market. Their cars are no where near original but they are some of the best driving cobras I have ever driven. They appeal to the hot rodder or the street rod guy that might want a something a little different or maybe a younger market. If you want original, then go with the FE and a CSX or ERA or one of the more accurate replicas. But if you want something different, not better or worse, through a coyote in a backdraft and hit the road!

You hit the nail on the head - well summed up!

[madmaxx]

I should have been clearer. Assuming just labor no parts install labor is about 2k. How much more does a coyote add to the install, not factoring in an cost for parts.

I think that when I'm done with mine, I'll part it out, will get thousands more for the car and engine separate than as a single sale item---------

VERY smart decision. Or spend the extra loot on an old beat up FE engine and you will still make out better than keeping the LSx in it.

[Jerry Clayton]

Oh, There are some FE's laying around the shop, but what I was implying? was that many more of my old engines and stuff are used as designer/collector coffee tables,etc, than trailer queen powerplants-------

Yet the majority of buyers out there still think that the LSx in a Cobra is dumb. No matter how badass of an engine it is, it hurts resale (perhaps not final value, but the amount of time to sell).

Now look at the pro touring 1st gen Camaros's with the LSx. $$$$$$$$$$$$$ That is a good place for the engine and they get the money deserved.

So back to the Coyote, I do believe that the market is extremely thinned out once you go this route as far as resale is concerned. Again, the final dollar may be close to an old(er) school powerplant, but there is little to no doubt that it takes longer to find that special buyer. It certainly steered me away from it, plus I wanted something with a nice cam anyway.

I think that my be related to your fuel of choice (or choice of fuel?) for those old soldiers, Jerry ...

I promise not to use H (hydrazine) never have----------
How come that post about the Elapsed Times magazine doesn't show up on these pages? or is it just my computer???

For Itstock----I intend to take my car to the salt flats and try to run 300 mph with it---will be a first for a cobra bodied car----one of the places where I haven't held a record.
After its over the car and engine can be separated-------

I don't know why the Elapsed Times mag post did not, same issue with my computer. To my way of thinking it should have because it was a - new post and an active thread.

BTW the write up and pics were absolutely great.

To my knowledge our body styles get to be a handful to control once you get above 150 or so. I think there has been only one of these body styles at 200mph. I suspect 300 might just be a stretch with out some wind tunnel work.

BTW that nitro with the greenish color to the exhaust flame was always pretty impressive. Seems like it didn't like too much direct sunlight on the fuel tank though and it always seemed to be a little alkali and shock sensitive

Don't do anything that'll get you hurt, we like you around here too much.

I have Roush 427 srtw with 8 stack efi for the look.

Next would be Keith Craft 482 shelby block.

Cobra is about raw insane feeling with the deep rumble - nothing less nothing more.

I know it is a replica, but when you open the hood or people ask... what will you say: defend the modern motpr or prodly flip the gas pedal so kids pee their pants and car alarm starts to chime

[CzyCobra]

Roush 427 SR here... Rated at 510hp but I'm trying to squeeze more out of it, first line of business is to install a set of Classic Chambered exhaust. As for the motor I'm thinking of letting my guy that built my motor for my 9sec 87 Grand National pull the carb, intake, heads and cam and put together a combo that can get me to 600-650rwhp. Or go the simple route and slam a supercharger on it.

I like the thought of new style motors in old Camaros and the 1st and 2nd gen Vettes but I bought this car because nobody my age has one. (32yrs) For me to put a Coyote motor in my Cobra will 110% defeat the purpose of me purchasing this car... Might as well of just picked up a Supersnake or that new Camaro that makes 600+ to the crank stock. (I still might get that Maro)

[DucatiThunder]

I went the 427 with the 8 stack. DEf a show stopper but a pita to clean. Once tuned its a good set up. Lots of different systems have come out since mine. I did like the 427 tilted look but wasnt an option at the time with a SB 427.
