What goals do you have with it?
More mods, just want the sound, make peak power, or good drivability. Lots to think about adn everyone has an opinion.
I've had a smaller Thunder Racing 224 cam that was an excellent all around cam, and now I have a more aggressive TSP 233/239 cam which works better with nitrous and makes more peak power. There are a lot of things to consider, but both of those cams had a noticable idle.
