About a year ago I did a valve adjustment on it and a tuneup with new distributor parts. While I had it apart I re-set the timing and the marks are still a bit off. Even at full adjustment they are still not lining up where they should.
The dampener looks fine and the tabs are still on the cover, but it still has hesitation when you really step on it.
In any case i've had a Pete Jackson Gear Drive in my tool box for about seven years that was supposed to go in a seperate truck I built for my dad long ago but he decided to go bigger with the heads, cam and compression, so gear drives aren't a good idea on H/C motors.
My motor isn't that H/O yet, so for now a Gear drive will suit it nicely as a tuneup when I put all new plugs, wires, valve cover gaskets and a new radiator in it.
