3500 stall?
3500 is that flash or brake? It makes a BIG difference.
However that is all by the by really as the real issue is the more power you have or rather torque means the torque converter will react differently.
If you put a 3500 stall on a stock Ls1 with ~345bhp and 350lb ft it will react different to fitting the same converter on a 500bhp/500lb ft engine.
the more powerful engine will stall the same converter higher.
In short you need a converted matched to YOUR car and mods and expectations.
If it was me I would not buy a 2nd hand torque converter. If you are prepared to pay over $300 2nd just save up the little bit extra you need and get a new one.

All IMO of course
IMO, I'd go with a larger stall, maybe a 4k, especially if you race the car. You'll absoluely love the 3500 though. Don't worry about driveability, it'll be perfectly fine.
