What was your argument again? I don't even have to look at the actual specs, part number of the cam is enough to know its close. 280 series grind on a SBC is the same as a 280 series grind on an LS which is the same as a 280 series on a sbf. For comparitive purposes both are OE hydraulic roller.
Since buying a shelf cam is RETARDED and custom grind is always the way to go, there's no argument to why what is what. These profiles were designed nearly 30 years ago.
