if so, how does it change the timing when you replace the gear set with the older ones. When my brother built his 460 one of the things (they) say to do is change the gear set to a early 429 set to get the cam timing back to center or straight up......if it was cut into the cams the gear sets would all be the same.

got this off the Cloyes website

Q. What years did Ford retard the valve timing on their 460 big block engines?
Answer:

All Ford 460 blocks manufactured between 1973 and 1987 were 8 degrees retarded in order to meet emmission requirements.

He dittos that in the 460 section. Their cams were also ground with a retard. Same timing set fits both the 335 and 385 series.

Somebody's wrong then somewhere. The set on this 351 has both marks in line with the crank key and cam pin. I might have time later today to get a pic.
