The 97 was designed for a 221 inch motor, cant see why it wouldnt handle a 200 inch engine.Henry Ford didnt like out side suppliers.The Dodge bros supplied parts for the early fords and owned a lot of ford stock.Henry got rid of all stock holders as he did not care for their attempts to control the company.Stromberg supplied carbs to many early auto companies.I find it hard to believe that they didnt build a good carb.Ive used both makes over the years and found both worked well if I used clean fuel and good gaskets.Ive run dual Strombergs on a 59a,tried adjustable main jets and found they complicated performance.Introducing a lot of variables makes it harder to get things working right.The troubles of the 12 volters is a perfect example of this.
