Mast is THE leader in LS cam technology. Want proof? We had variable valve timing cams 18 months BEFORE anyone in the aftermarket. We design our lobes IN HOUSE using proprietary software. We test each cam on our NCRS Superflow engine dyno in actual applications to find the best power curve. Then, we test each profile in “real world” conditions. After many grueling hours, we select a profile to be manufactured to our precision specs. from select billet cores. Mast Motorsports cam & valve spring package notes:
  • Each package includes a Mast dyno proven camshaft PLUS matching Mast premium beehive valve springs
  • Mast premium nitrided beehive valve springs are included with Z06, HO & SS cams
  • 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. Idle Quality: Moderate Duration @ .050": 224 In./238 Ex.
