Coyote blueprint specs changed

[kdanner]

I can only guess, but my best guess when I initially read this was that someone had entered as a 2014 but actually used heads with at least one of the differences in the 13 head which are:

1. CNC ports/chamber
2. Larger exhaust valve


Am I getting warm?

I can tell you you're warming up but it's much deeper than that! If NHRA racers had any idea they would all have a fit. Issues like this should never be ignored no matter what brand you race. These oversights erode the foundation class racing is built on! Keep digging and maybe someone will give you a reasonable explanation but I doubt you'll get one from the tech dept.

Its called running heads that didn't come on a certain combo from the factory. Bigger valves, cnc chambers and runners, having pistons custom made to not hit the head... because it didn't come on a 5.0 coyote motor. But somehow it got approved by higher ups. Then gets the combo hit with a 1.20 under with what should be an illegal engine combo. That's all I'm gonna say about it but believe me, there is a lot more to this certain story.

How interesting. I don't even know who you are, but that is exactly the same story I have heard somewhere else, and it was concerning exactly the car which I suspected it was.

I didn't know any stocker was allowed carbon doors either, but evidently I was wrong...

Damn, sounds like someone has been poking the bear ......

"The Coyote blueprint specs have been changed."

Maybe that should say...The Coyote blueprint specs have been corrected.

Question...Was the -1.20 under car at the D-1 race torn down and checked? If not, why not?

I asked that at the time. A photo was provided of the car in the barn with the throttle body removed.

Carbon Fiber Doors AND Optic Armor polycarbonate windows. Is it a coincidence that there are only 2 CJs in the country with these lightweight parts and they run out of the same shop?

I possibly have the same problem someone else did which led to these revelations. This is the piston Mahle sold me. Anyone happen to know if this is the one where the dome will hit the chamber unless it is a CNC chamber?

He's the brother of Jeff Hairrington who runs this combination with the CORRECT heads and is now the one holding the bag of horsepower that the other one got running the combo with the wrong heads on it.
