People are amazing. First off as far as I can tell from every thing I have read both the SRT6 and regular models are made at the AMG factory. I have not read anything to the contrary. Secondly if they are not AMG engines I won't and would never put an AMG badge on it. I'm pretty new to the Crossfire and didn't know. Be like putting an SS badge on a stock Chevelle. Thirdly: don't get your panties in a bunch, some of us are still learning.
