Hey guys,
I have an 09 Hemi Sport. A valve stuck and roasted the cam 6 weeks ago. I asked the shop to do an upgraded cam and after putting it back together and hand turning it, they have a piston hitting a valve.
I asked for a mild cam and they installed a Comp Cam 266. They had a "specialist" come and look at it and he thinks the Cam is wrong. After looking at the specs, on Summit it says it only fits years 2010 and above. Mine's an 09.
Comparing the specs to Moes high performance cam.
**266 Specs:**
Intake Duration at 050 inch Lift: 218
Exhaust Duration at 050 inch Lift: 226
Duration at 050 inch Lift: 218 int./226 exh.
Advertised Exhaust Duration: 279
Advertised Duration: 266 int./279 exh.
Intake Valve Lift with Factory Rocker Arm Ratio: 0.612 in.
Exhaust Valve Lift with Factory Rocker Arm Ratio: 0.605 in.
Valve Lift with Factory Rocker Arm Ratio: 0.612 int./0.605 exh.
Lobe Separation (degrees): 114
**Moes High Performance Cam Specs**
Duration @ .050: 210 Int/218 Exh
Lift: .587 Int/.580 Exh
Lobe Separation: 112
Question for the Cam experts is, is the 266 wrong for this 09? They said they verified the timing.
Also, new springs were already installed along with a full valve job. I'm assuming this will work with Moe's cam should I need to go that route.
Thanks for the help, I really appreciate it.
