It looks like I was sorta kinda right. The idea is to increase net lift by opening the valves more quickly than a stock cam, while still conforming to the stock cam specs because of a class racing restriction.
I think these were also called "cheater cams" but it's been a while since this stuff was important. They must be a lot harder on the valve train than the stock cam--there isn't that gradual take-up of slack when the valves are opened and closed. Of course racing engines aren't expected to go 100k and if the entire valvetrain is HD aftermarket stuff maybe the durability is still there.
Maybe that's why your Pontiac spins the tires going into second ;-).
