A little speedo gear help needed please.

With a the changing around on my 86 C20 I have done. I thought I had it figured out when I ordered the new trans. Well I'm running a good 10 miles an hour fast, at 25 and 35. Then at 45 it spreads out a bit more. I have a 4X2 with a turbo 400, using a 44 tooth gear in a 40/45 housing.
I have here a 40T and a 41T gear, do you think these will help me get closer to my correct goal? I'm running the stock steel 16X7 wheels, and 215/85R16 tires on all four corners. I know more info is needed, just thought someone might know right off hand. Thanks Ken
