For those wondering when the 12-13 engine update occurred:

Did a preemptive tear down and build (looks great) of my 2/12 built 12 gt and found a few things others may find interesting/helpful.

Evidently the cutoff date was before my cars build.

1.) It does NOT have oil squirters.

2.) Pretty sure It is already modified for the 13mm cams.

3.) Torco puts red stuff everywhere, as expected. I ran this car around 700hp for over a year with many many track passes with no issues. Worth it.

Piston skirt. Ignore the scratch, that came from removal lol.

My 13' had oil squirters.

But i had the upgraded pistons

They didnt know what the heck they were putting in what then haha. Did you have the clearanced heads? I thought I lucked out when I didn't have to buy the squirters deletes, then ended up having to buy the smaller head studs.

I assume I had the upgraded pistons. I don't know the easy way to identify them.

I had the smaller head studs too. Dont know about clearancing as i had my done more. Didnt even check

I bought a truck engine to use as a core dated 10/2011, heads clearanced for the roller finger followers as well. That started at some point prior to the block changes.

Thanks for the info. Makes me wonder the reason they put squirters in some, but not others.

Kind of wishing I bought the 13mm 290 cj exhaust cams instead of the 11mm version. Oh well

Why where they still building 2012 models in June of 2013?? My '13 was actually built in late '12. Surely there weren't building both '12s and '13s at the same time?

Can't answer that only can go by build date on VIN tag.
