Mast Motorsports L99/L92 HO Camshaft 224/238 Duration .578″/.593″ Lift – 115 LSA

Mast Motorsports had variable valve timing cams 18 months BEFORE anyone in the aftermarket. They design their lobes IN HOUSE using proprietary software. They test each cam on their NCRS Superflow engine dyno in actual applications to find the best power curve.

Headers are recommended on every GM Gen IV app. to significantly enhance power improvements from camshaft swap. Mast Motorsports recommends that every cam be accompanied by a calibrated tune using HP Tuners, EFI Live, or equivalent software.
