I have read on the web and on this board that Buicks with the ST 400 didn't have the Switch the Pitch converter...but, Every road test(have the Brookland books on Rivieras and the General Muscle portfolio 1963-73) I have seen of Rivieras, Electras, Wildcats from 1964 rave about the feature. So....did the car mags have pre production cars with a feature that they didn't release til 65, or was it a late model feature, or are a lot of people wrong and all 64's with 401's and 425's had them??? o No:
Conrad-I'm into '65-6 big cars and will say that I've not seen a '64 with the switch pitch-'65 was the first.
