At a swap meet this weekend a discussion came up that <b>only</b> the 1963 HiPo engines had a four barrel intake. From my reading of Bob Mannels book, I believe that the intake could be purchased over the counter or installed late in the year on production vehicles. I do not have the casting date presently of the intake in question, but it was a C3 intake with a PCV routed to the carb spacer from the ventalation hole; as pictured in Mr. Mannel's book on page 3-24, photo3C4. What are the thoughts of others?
Thanks, Joe.
