dumb question about camshafts

[IMFASTTOO]

Cams alone will net very little, without already having intake and exhaust opened up
plus you'd likely mess up your valves and shim/bucket train without upgrading them too to be able for more aggressive csms

YOU must do the intake and a complete 3into 1 Exhaust and cams ,springs, buckets, shims etc. and then you can produce 200+HP THIS would be the same parts as the 210 package minus porting the head
