i have full bolt ons with 210/224 cam

which would be better?

I'm surprised they are even telling you that they can get the stall speed within a 200rpm range without trial and error. The will almost certainly be indentical converters with the fins bent to a slightly different angle on the stator. Assuming that the two different configurations actually work as planned, the loower converter would gave better launches on a sticky surface with sticky tires but will tend to be more annoying on the street. Louder, decreased mileage, harder to control wheelspin. Overall though, a nominal 200 rpm difference is very small.

So can a camed LT1 run a 3200-3500 stall and still have decent street manners?? Stock LS1's can get away with it no problem, but I know the higher stall is recomended for LS1's due to a higher powerband, so I figured a camed LT1 would have a higher more similar powerband to an LS1. Does that make any sence??

 

Everyone has a different idea of what is "acceptable". There is no objective standard to go by. Besdies the individual subjective aspect, the kind of driving you do will play into it. High stall converters are at their worst in stop and go driving. But more objectively, as I stated above. A converter with a relatively high stall (over say ~3,000rpm) is probably not going to make your car faster on the street. You will just spin the wheels earlier and harder. Obviously, the rear end ratio will play a role. If you still have 2.73's a high stall will not pose as much problem with controlling wheelspin. But if you have installed a shorter rear end gear you will just go up in smoke.

My own preference is to stick with 2,800-3,000 for a car if the goal is to optimize street use. If you are trying to optimize for the track (sticky tires, prepped surface) go higher.
