Usually 8" converters are less efficient and have more slippage. I don't think they are surprised it is a 3800 converter, given your combo, I think what surprises them is that it's an 8". I'd run a 10" converter with around a 4000 stall.... IMHO.

10 inch 4000 converter will have more slip than an 8 inch 4000
