727 or 904?

Thanks for the converter advice but I'm asking about the transmission.
Race.....youl be hard on it....... and a 2800 converter? Seriously? Put 4500 or 5000 stall speed converter behind it. Sheesh. Save yourself the $ and put the stock one back in. Nothing wrong with a 5000 stall in a hot street car. Yes, I have personally done it and would again.
