What was Holley's biggest carb in 1960?
Near as I can figure:
390cfm = 1957 312/245
450cfm = 1958 383/312
550cfm = 1958 383/330
600cfm = 1958 430/360
So Ford could have gone up to 600cfm for the 352/360hp.
Strangely, the Dec 1960 article on the new 390/375 (600cfm) says NOT to backfit the big 600cfm carb to the 352/360hp. Both seem small to me.
715cfm = 1963 427/410
780cfm = 1965 427/410MR
850cfm = 1967 427/L88 maybe
950cfm = 1968 427TP 3bbl maybe
1050cfm = 1969 429 Boss Dominator maybe
Just guessing on those last few.
