I get 21 on a 235 with dual Offy/Holly Weber/Howard M4F cam setup.
Next month I go bolt in (our 41 Sedan) a OD and 1958 rearend. Hope that helps the milage.
Gas is verrrrry expensive over here in Germany. About $ 5,56 a Gallon low octan pump gas!! (1.15 Euro a liter)
You folks live in a cheap gas country ;-)
That`s why lot`s of guys over here experiment with super carbs, fuel heaters, PCV-Jars, Hydro Boosters and whatelse.
Some of this stuff works only on pre 1970 engines without electronic emission stuff and cheap single grade oil. Only fuel heating (wich is verry popular here) works for injection and saves 10-20%.
