Thanks for the comments guys. Keep in mind this is a street legal road course car. For road course and reliability its NA build.
The coyote motor would be more reliable and better gas mileage and could make more power N/A than the old 4.6L.

your wasting your time and money on a coyote
the top end is weak and will fail at the track. period.
the block is also weak and cant compare to the teksid, not even even with the FP race block .
or a sleeved block.
A teksid block is the absolute strongest short deck modular block on the planet.
coyote heads are weak and fail often in all venues.
even with the vct cams removed or locked out.
the Nemak heads found in the GT car / shelby gt500 / 2000 cobra R / fr500c are the best heads hands down. and they are not as popular as coyote and can be had for less than coyote stage 3 race heads! but they are better for any track or race engine. They out perform coyotes out of the box.
these heads fit your engine and not the coyote.
the coyotes need to be rebuilt to race, even the aluminator.
only the xs is track worthy and thats why it lists at $19,000.
the XR3Z cobra block with GT heads will even out perform the XS with matching components.
then there is electronic controls
another can of worms for the coyote racer.
serious racers (coyote and mod) chuck the ford package for better control and a real throttle link.
FAST, HOLLEY, MOTEC, BIG STUFF, MSD ETC.
Pus you can have an emissions tune and street tune and track tunes to shred any bed.
in the long run the coyote will cost you more to make the tractable day in / day out power you need. a lot more since you dont have a coyote car.
otherwise your just playin games.
Distributor? MSD, with a Fast Box Attached.
how much do you want for your 99 cobra track car?
lets see some pics...
Livernois considers it the best 4.6 block cuz it's the FOMOCO replacement block for all 4.6 hi-po svt/ford cars and its in stock, ie cheap. Nemak tookover Teksid years ago ending production of the "best blocks" abruptly, pissed off Fomoco. Cosworth has many success and failures under thier belts. and they dont mind doin stuff on the cheap. you get what you pay for. look at the complete history with ford. look at the new Aston Ford Cosworth v12.
anywho i say the late teksid is the strongest and accufab is proof. l think they hold the record for
highest specific power output
of any automotive engine in history
(production block) , HORSEPOWER PER CUBIC INCH.
Was previously held by GM/OLDS/FEULING turbo 4 with over 1,270 hp from 121 cubic inches. at 281 ci that Accufab mustang must be making 2,800+ to run those numbers. (all year long same block!)
Your car reads wicked, curious if you know lb-ft. at crank or tire?
ps. Cosworth was involved with the Olds project.
So does that mean you don’t drive it on the street much?2/3s plus of the miles are logged driving to the track. HPDE are 20-30 minute tops sessions. It is not racing. Car handling is fantastic just underpowered for the weight for a road course car.
