The cam you have won't be awful. But if you're looking for a am that will just work well and have a set and forget style, then think about an LS9 cam. It won't wear out valve springs and it's made for a blower.
If you're looking for a little more max effort, you're looking at something more like what you have, but with a wider lobe separation angle. 233/239 is a good split. Much more duration than that and you're going to push the power band way up the RPM range.
But with a blower you're going to want a 116 or even higher lobe separation. The less overlap will help with the forced induction. What we usually do to help bring the power band down into a usable range is to advance it. An adjustable timing set with +2 or +3° makes it friendly.
But the wide lobe separation takes away from the muscle car sound. The tight LSA is what makes a car idle choppy. The wide LSA will make it idle smoothly. You'll have to fake the cammyness by throwing the idle spark table adjustments.
