I'd think about these more after tuning is available but they are something to keep in mind -

New XFI. Camshafts Deliver Big Power Increases For Late-Model Chrysler Hemi 5.7 and 6.1 Engines

Three different camshaft combinations net power increases up to 61 HP COMP Cams New XFI. (Xtreme Fuel Injection) camshafts for Hemi-powered Chrysler vehicles dramatically increase engine horsepower and torque, yet retain compatibility with all OEM vehicle computer systems. Available in three different profiles (XFI 260, 268 and 273); the new camshafts are application-specific with designs for street performance and towing.

In recent dyno tests on a Hemi engine using COMP's #26918 beehive valve springs and upgraded exhaust, the XFI 260 netted 20 additional ft pounds of torque in lower rpm ranges with a peak of 31 additional hp. The XE 268 camshaft added 14 ft lbs of torque at low rpm and 47 additional peak horsepower. The amazing COMP Cams XFI 273 camshaft yielded it's most significant horsepower increases over 4500 rpm generating 61 more horsepower than the stock Hemi 5.7-liter engine.

"We're extremely pleased with the power gains we have achieved with these camshafts," said Scooter Brothers, VP of Engineering. "When we set out to offer specialized Hemi camshafts, we had an acceptable power increase figure in mind. We have far exceeded that original target figure and believe that these three camshafts will offer customers the ability to find the exact camshaft that is right for their vehicle, car or truck."

A "Tuner Package" will be available in the future. This will include the cam and Fast-Flash programmer for optimized electronic tuning.

112-500-11 - 208 212 .522 .525 @ 113 - Hydraulic Roller - Slight noticeable idle, requires modified computer, excellent torque throughout range $379.99

112-501-11 - 216 220 .528 .531 @113 - Hydraulic Roller - Noticeable idle, requires modified computer, strong midrange $379.99

112-502-11 - 224 228 .547 .550 @ 114 - Hydraulic Roller - Needs Extended rev limit, requires modified computer and better exhaust, strongest power over 2500 RPM.$379.99

We also have springs and retainers available.

Do you have a cam/spring kit with the 273? With some kooks headers, cat-back and an intake, this should easily pull on the SRT!
