Mike:
With all due respect to Devin's reply, I would not use trial and error to
install your starter. You may damage the starter bendix gear and/or the
teeth on the flywheel/flexplate.
Most replacement starters for GM engines come with a shim package. Included
in the shim package is a small diameter rod to measure the distance between
the starter bendix shaft and the flywheel/flexplate. If you don't have one,
go to a local FLAPS, they usually have extras on hand. Some shim kits come
with short and long shims for positioning the starter. Short shims to add
clearance on one side only, long shims to add clearance for the whole
starter (both sides).
With the starter bolted in place (no shims), slide the rod between the
bendix shaft (not the bendix gear with the teeth) and the flexplate teeth.
Use your judgement, if the pin appears too sloppy, loosen the starter and
slide shims under the outside (closest to the framerail) bolt. This will
'tilt' the starter closer to the flexplate. Retighten and recheck until
you're satisfied with the clearance.
Conversely, if you can't get the rod between the bendix shaft and flexplate,
loosen the bolt closest to the engine block and add shims to this side (it
will 'tilt' the starter away from the flexplate). Or you may need to add a
long shim to position the starter evenly. Repeat as above until you're
happy with the clearance.
Doing this will ensure the bendix gear engages properly and doesn't damage
the opposing teeth on the flexplate.
Hope this helps.
