I had Charger RT/RT there is alot you can do to motor , A hand held tuner can be had for under 300.00 that could give easy HP out of this motor, RT came with 340 RT/RT came with 350 . With diff cam and a tune you are looking at about 390-400 hp,but like the rest of you for 16,000 a srt would be the better bet , but to have that one of kind would be cool but not 30,000 cool
