Questions about this item
Which ratio fits my 302 build — the 1.6 or another option?
This set is the 1.6 ratio for 7/16 stud Ford small-blocks. It replaces stock 1.6 arms directly and adds roller-tip action for reduced friction.
What does the 1.6 ratio actually change on a 351W?
The 1.6 multiplier increases valve lift and duration by 16 per cent over the cam lobe, improving high-RPM breathing on 289, 302 and 351W engines.
