<p>You can set your cam timing to an exact point. Within a
degree or two. with the stock stuff it's more like five
degrees. It makes a difference..........................Henry

>> I am getting back to my Healey 3000
engine rebuild after two years. I bought the Roller
master vernier timing gear set from Moss at that time.
I have previously used the Roller Master gear set with
multiple key ways to adjust the cam timing with no
problems on other rebuilds. What I don't like about this
set is that the cap screws used to clamp the vernier
gear to the hub are not very robust. Working in aviation
I have AN-4 bolts that I can replace the cap screws with
and safety wire them to prevent slippage. Has anyone
using this kit had problems? I could keep the cap
screws and Loctite them. This is a street car, not a
race car. Pictures are one bolt installed and the
hardware side by side.<br>
