I have recently purchased a running motor out of a 1999 cobra, and when it was out I had noticed it had some different tags and markings on it.
The heads have the castings are RF-YR3E-6C064-AB
and the block casting are RF-FL2E-6015-HE
it also has another tag on the block that says 06/28/2011
any help would be greatly appreciated! thanks!

Based off of those P/N's the heads are 99/01 C heads. The block is a teksid (96-98 but some made it into 99's).

Best way to confirm the block is by looking in the valley. If the valley has a grid iron pattern its a teksid. If it has a diamond shaped patter is a WAP block.

Teksid blocks made up into 01 Cobra also .
Yup all the 99s had the teksid block and about half the 2001 cobras as well.
The rest of the 01 cobras as well as the 03-04 mach1s got the short lived WAP block.

The 05-09? got the 4.6 cosworth "aluminator" block, which I believe is pretty much a copy of the teksid block...but even stronger.
