Viper cam swap is very similar to the Corvette. Maybe even better, since there is a lot of room in front of the engine. You'll have to remove the oil pan to get the front engine cover off, because the silly oil pick-up tube is attached to the front engine cover, and can't be removed without taking the pan off. Luckily, there is no k-member to get in the way. Honestly, it would be easier to just pull the entire engine out to do the heads and cam install. I know I save time by doing that, and it is easier to work with it out of the car. I can pull a transmission off by myself (using a lift, trans jack, etc...) in just over an hour.
As for cam specs, if you want good mid-range and throttle response, a lower LSA does that. But, that also increases lope.
You'll likely want to do a 3.33 or 3.55 gear swap at the same time, as these cars are already slow to get off the line with the 3.07 and you'll end up burning up more clutch at red lights with the cam.
