It can be EXTREMELY amazing! I bought a brand new "151" 350 HP Chevy cam across the local Chevy dealer's counter about 1968. I threw it in a little 283 I rebuilt for a friend's '61 Vette. Had hell trying to initially set some of the rocker arms. That thing wouldn't crank for nothin'. We even tried pulling it...notta! After much butt-scratching, I pulled the cam back out and laid it beside the stock cam. NINE lobes out of sixteen were ground nowhere near where they were supposed to be on that stick. Only after finally convincing the guys at the Chevy house to lay another cam beside this one did they believe that this cam came from the manufacturer ground this way. DD
