Jack's Comments:
This is the decal that identified the specific engine version called out on the factory build sheet. It should match your engine build sheet code or the factory aluminum engine ID tag (see notes below and pictures).
Correct for all R-code and Q-code 428 Super Cobra Jet engines.

Q: What engine ID code should I choose?
A: This tag matched the die stamped aluminum engine ID tag (scroll down to see picture below) was held on the engine with the coil bracket bolt. If you don't have your original aluminum engine tag, build sheet or Marti Autoworks supplied tag their is no way to say 100% what number your car came with so you will need to make a guess. Below are some Cobra Jets we verified but only one of them is a Super Cobra Jet. With your cars production date on hand you may be able his may help you to choose an ID tag number that is would be closer to what your car came with from the factory.
