Been mulling around whether a 6.1 could be "readily" installed in an '09 R/T. I really like the options that the R/Ts provide, like the Titanium color (not available on SRT) and am frankly less worried about the improved handling and braking of the SRT. So, buy an R/T, pull & store the matching #'s 5.7, install a Mopar 6.1 and create what I really want. I believe the bellhousing and transmission (manual) are the same, I'd probably need to switch to an SRT computer too. Other than that, I believe mechanically they'll swap together.
Thoughts? Yes, I am crazy...
