giacomo has it about right. The '64 300 horse 390 was the standard performance 4V mill with a VIN -Z- code for the full size Ford/Merc. The '66 Fairlane, and apparently '67, also had the -Z- code standard performance 390-4V. The '66 390 -Z- code heads were probably C6-R or C6-U with a standard for all 390-4V's for '66 & up - the cast in S intake manifold. If I remember it correctly, the '66 standard 390-4V was rated at 315 horses. Most of the '67 390 standard 4V and GT got the C7 heads. And to add to the horsepower rating confusion, the '67/'68 390GT got a 320 horse rating.
I think it was 1967 that I gave up trying to make sense of Ford's horsepower ratings. |
