I would think as they would have had to disconnect the battery for more than 20 mins to do the motor swapTMSBOSS said:

No codes in the PCM when engine failed... Battery was disconnected for hours during the engine swap... Easy to replicate P0304 code at approx 4,000 RPM this AM on the way to local Ford Dealer...
Gave them the TracKey Install instructions highlighting the symptoms and the Crankshaft Re-Learn recommendation... They did the original TK programming and never had a Misfire until after the engine swap...

Hopefully that fixes it, but like Pete said everyone that I know, or who have reported it on a forum, experienced the random misfire issue on track.....other than zzyzx.07SGT0547 said:

So far so good... No more codes with either Key... Will be a month or two before I get enough "break-in" miles on the new Engine before I get it back to the Track...

Could you tell us what the dealer did in your case? Did they confirm they did the crankshaft re-learn procedure? Just curious as mine is going in next Tuesday and I plan to write-up what others have had done to resolve the issue.

That was all they did... And I specifically asked the Tech if he went thru the whole TracKey re-install process and he said "NO"...
Although it isn't called the "Crankshaft Re-Learn Procedure" on their diagnostic laptop computer, there is a specific menu item that addresses this particular issue...
And if your servicing dealer is having issues or not familiar with this problem, have them give mine a call (Louisburg Ford in Kansas ~ (877) 901-4311 and ask for "Johnny" in the Service Dept... Other than the one 2012 Black LS they ordered for Hennessy in TX, mine is the ONLY other BOSS 302 they have seen or worked on, to my knowledge... Good Luck!
I confirmed that one of the other engines that had been replaced broke a timing chain and basically destroyed the engine. So it was not related to the #3 cylinder issue.

Looks like another "Spun Bearing" failure... This time it was Cyl #8... Yikes!!!

Maybe he can post here to see all of the details? There really has not been alot of problems with the Bosses being how many they made and it does look kinda like the first ones that rooled out maybe had a few extra problems but who knows why and wonder how many gt500's motors blown?

Will the random misfire generate a check engine light/code? Sorry if its an obvious question.
If so, what is the remedy?

It it happens more than the Max unreported threshold it will. The reasons can be varied. The solutions vary based on reasons. There is no straightforward answer here.

I find it odd that there would be any severe failures. Didn't ford run this (almost) exact motor in grand am or something for an entire season, with multiple cars with zero failures. That's 100% track duty.
4000 12s sold, how many blown motors? About 10? That is 1/4 of a percent. And on a car that probably has a higher percent of owners tracking them at least occasionally than most other cars. They appear to be standing behind the motor 100%, and not playing the owner abuse card which many brands will do. I don't know what the numbers are for other cars, but that doesn't seem too bad for a 1st year of the new heads.
Track cars are also very closely monitored, so they might have caught issues before they came up, and the pre-production ones were probably hand built using hand picked parts.

There have been failures including one last weekend at Sonoma.Tflong24 said:
I don't know all the details. Considering they are untouched assembly line engines they are doing well. Other than emissions and tune they are identical to the ones used in our cars. I don't know about you guys but the redline on my engine is 7,500 RPM's and I verify that often.
