doing a cam swap isnt hard at all with LS1's. Ive done it twice on my WS6 and can get it done in a couple hours easy. So much easier than doing it on a LT1. Tuning is always the hardest part of a cam swap.
I was told that this one does not "need" a tune in order for your vehicle to operate. It will be beneficial to do so, though, for obvious reasons.
It's the biggest CAM possible without having a rough idle or a necessary tune.
