dont quote me on this, but i beleive for 09 the 5.7 is rated at 390 hp and the 6.1 at 425. i personally would not spend the money for an srt, unless you are just worried about the package.

the 6.1 has been around since about 05
and the 5.7 is the new Eagle 5.7 hemi in 09. It has variable cam timing, different heads, and a different intake from previous 5.7 cars and trucks.

There have been quite a few posts here where 5.7 cars have out ran or at least kept up with a 2008 6.1. the 08 6.1 autos did not have the 3.90s that are now offered in the 09 6.1 manual trans cars.

i guess what i am saying is an 08 srt auto car to me is not very impressive, mainly cause of the rear gear ratio.

the 09 5.7 stick cars comes with 3.90 and 390 hp
the 09 6.1 stick cars comes with 3.90 and 425 hp

i will let someone else chime in thats actually got money to drive one
