Anyone have a set of timing gears handy for a SBC????

[Bob S.]

Hi -

I'm wondering how many teeth are on the crank and cam gears. Anyone have a set of gears they could count the teeth on, (or know the numbers off the top of their head?)

Thanks in advance for any help!

Regards,
Bob S.

I don't have one handy, but as I recall it's 19 and 38.

It's 18 and 36. As a matter of fact, the same timing set was used for Mark I big blocks (348, 409) but not for Mark IV big blocks. Mark IV big blocks use the 19 and 38 tooth count.
