Geez, I know that a lot of folks dont like the gear drives, but I was hoping more people would fess up to using (or, having used) them and offer their perspective

I am just searching for opinions. I am sure that the "mature" hotrodding croud here at CHR would think no less of someone for admitting that they have a gear drive.

Hopefully some more will chime in...

Well, good to see I'm not the only immature one here anyway!!!

If results don't worry you, then just add some shims or maybe two bearings behind the cam....though retention could become a problem...or maybe a bit of tweaking on the crank gear so it will slide on further.....Possibly a shim and longer bolts (if required) between the camshaft and the cam gear????? I wouldn't recomend doing any of the above, but if your goal is to run a gear drive, these are possiblities that I could come up with

I've seen some variation on the offset of crank and cam gears from manufacturer to manufacturer,,,,Could this be your problem???

And I did confess to using them, but it was on a sprint car with no harmonic balancer, a Crower billet crank with Carillo rods.... It was all we ever ran til the good double roller sets and a front cover that would allow the usage of chain and gears and still be able to use a cam driven water pump and crank driven fuel pump (or was it vice versa?) Anyway, this was in probably about 1973, sorry if my memory is a bit foggy on what was driven by what... hmmmm, now that I think about it, I think the crank drove the water pump........ dang CRS anyway!!!!!
