GSC Power Division Stroker R2 Camshafts The 7008R2 is a high lift, very aggressive profile, with a short overall duration to keep a lower usable RPM band. The 7008R2 is designed to rev between 4000-8500 RPMs and should be used with a stroked engine or added displacement engine. The peak lift of 12.0mm intake and exhaust will require upgraded valve springs and a titanium retainer with special attention to seal to retainer clearance. With the lift of this profile, it is suggested to only use the 5041/5040 Ti retainer and spring kits due to valve seal to retainer clearance. The 5041 can be used to 40+psi and the 5040 to 32psi on the R2 profile at 8500 RPMs without float or flutter issues. The profile will work fine on the OEM rocker arm and the zero-tick lifter, or with the OEM lifter. We have seen gains of 25-30 WHP over the S2 profile on the stroked applications, with much more possible when used with a ported head and aftermarket intake manifold.
