I've got a 3500 stall 904 unit. It worked good for me. I'm putting that engine/trans in a street car and that's a little too high for my liking on the street. I was looking around at Summit Racing for a Hughes 2000-2500 stall and found out that they now charge a $100 core for all their converters. I didn't see that any other converter manufacture was doing that.
I bet used cores are almost impossible to find. A budget 2000 - 2500 like you are looking for is probably made from a stock converter. How many of those could still be around? Spend 2 or 3 times as much for a good converter that is made for your application and you will be much happier. You CAN have both higher stall AND far less slippage in a good modern converter. Better performance and better drivability at the same time. Win Win.
