Car has LT,no cats,hot cam,LM1,fresh rebuild on block/M6,4.11,AC delete. How much HP should I expect to see? And should any more prep be done before tuning? I'm from Illinois so Im thinkin Speed Inc will handling tuning

Lol @ old man cam, previous owner chose that cam. I dont think the heads was massaged,I can look over rebuild sheet. I do rememeber reading 93 octane only written on a page inside the dozen or so for the rebuild.... Deck milled?
If I wanted to swap cams, and the hotcam is not that terrible IMO what would be a nice upgrade? Cam swap with engine in is possible right?

This is a toy, when I hear about driveabilty with cams ..what exactly does that mean. This is my first M6/cammed car and I do notice it can be a chore (minor though) in low speed parking lot setting,but I chalked it up to the Spec 3 clutch since my buddies stock Z28/M6 is more tolerable.

With regard to driveability...Big cams(TRex, Polluter, MS4 etc) with a lot of overlap tend to need more fine tuning to make them more drivable. A big cam with a poor tune, or no tune will buck and surge, stall the engine at low rpms (under 1800). A tuner worth his salt can usually make even the donkey dick cams ok at lower speeds/rpms. Keep in mind while they can be made drivable, a bigger stick (230+ duration, 600+ lift) is going to be tougher on the valve train, more wear on lifters, springs, rockers etc...You might just see if you are happy once the LS6 intake is on and the car is tuned, if not, there are plenty great cam choices that are not max effort.
