'66 428 PI cam specs |

My source says it was mechanical, 306 duration intake/exhaust, .500 valve lift , 78 degrees overlap, and marked with a upside down triangle and a "B" between the last lobe and last journal. 1965 390 PI 282 duration intake/exhaust, .440 valve lift with 54 degrees overlap, marked with a upside down triangle and two 'A' s. Looks like the 428 PI of '66 was the same 390/406 4v,6v 8v cam, #C3AZ-6250-D This info came out of one of the old OFF-HIGHWAY parts books. I didn't know ford put a mechanical cam in the 428. Maybe they did or maybe they had a hydraulic one with the same specs. |
