Hemi Cam Suggestions
- Thread starter JohnHancock

exactly which hemi and displacement are you referring too?
yeah Id assume its a 5.7 ltr dodge hemi ?
what transmission and rear gear ratio?
obvious;ly doing rather extensive research would help.

Id probably go with a cam similar to this route,

as it should produce a noticeable boost in mid and upper rpm power,
but it would require a higher converter stall speed
and several other mods to sensors, bigger injectors, and perhaps larger fuel lines and
maybe a bigger fuel pump if you want to consistently exceed 550-575 hp

and free flow low restriction headers/exhaust
but something in that lift and duration range would be a good upgrade over stock.

Stage 2 Turbo HRT 229/237 Hydraulic Roller Cam for Dodge HEMI 5.7L-6.4L w/ VVT 2009+
Add up to 180 horsepower with the Stage 2 Turbo HRT Cam for Dodge Hemi 5.7L-6.4L w/ VVT 2009+ applications. Best camshaft for larger (80mm+) turbochargers with optimized low back pressure systems. Dyno tested to 7500+ RPM. Requires DOD Delete Kit, #7230 valve springs & phaser lock.
but its certainly not a drop in and drive option,
you'll need several other upgrades to the valve train and clearance checks
