As you say "depends on your tastes". For some , anything looser than a stock converter feels mushy. Others don't mind cruising around with their 4800+ stall 8 inch. Personal experience has shown me that having a stall speed well above cruising rpm is not a problem. My 73 RR with 2.76 gears has a 175k MP converter that flashes to about 2800. My 68 Satellite with 3.23 gears has a 9.5 inch Dynamic converter that flashes to about 4500. Both cars are drivers (I don't own a modern car) and their transmissions haven't been out in over a dozen years. With a good cooler, heat is not a problem. Even some stock vehicles will have a converter with a stall speed a bit above what the cruise rpm at 55 mph is. My 318 duster had a 904 with a stock converter that flashed a bit over 2000. With the 2.45 rear gears , 55 mph was about 1700 rpm. I've known many people over the years that bought entry level 11 inch "street type" converters because the magazine articles of the eighties had them convinced that they would burn up their transmissions if their stall speed was over 2500. When they finally switch to a quality 9.5 or 10 converter they were amazed at the performance difference. And let's not forget all the guys that drive 1000 miles on Drag Week every year with those high stall converters coupled to Gear Venders overdrives. And I don't think the OP mentioned OD anyway. I'm not that knowledgeable about turbos, but I believe that more stall speed helps build boost. And I don't think they need much gear. There is a member on Moparts named Dizuster that has a badazz early B body with a turboed 360. I believe he runs 3.23 gears. For those that are interested, go to Moparts and search out his posts. they are very informative.
