Stromberg Carbs 81s 97s & 48s

[STAN WHITE]

I know a little about these Carbs. I had a good friend that asked me why I was USING 97S on multi carb setups. He only used 48s due to their larger size = more CFMs. I run three 48s with no progressive linkage, Works great for me. I would like to know what year ford started using the 97, and I have heard that the 48s were only used for one year. If this is true what year were the 48s used. I know that the 81s were used on the V8 60HP engines only I think that ended in 40 or 41. Thanks Stan White
