Holley vent whistles
I had my Holley 1850s redone.When they went away they had the white plastic vent whistles.When they came back to me they had a small brass devise that partialy exposed the vent window diagonaly .It is hung off the pegs that hold the bowl gasket.It is formed from sheet stock. Anyone have experience with these? are they better than the vent whistles?Why do you think they switched ? Should I replace with the new white plastic vent whistles ?
