A gilmer drive is a syncronous drive system using a cogged belt. They were developed by the R.H. Gilmer company and first available for sale in 1949. Timing belts are a type of gilmer belt.

Overview
Gilmer belts differ most importantly from V-belts in that they are synchronous. They do not slip as they turn, so are suitable from driving the camshaft. They are also stronger so can turn a supercharger. They are lighter but more expensive than V-belts. A serpentine belt is a less exepensive version but is not synchronous (will still slip slight during normal usage).
Aside from timing belts, Gilmer belts are most famously used for Supercharger belts. They are also somewhat commonly used on race engines for accessory drive (driving the water pump, etc).

How To
Using a Small block chev (SBC) kit.
The alternator pulley goes straight on, water pump pulley just needs the Center machined out a little and for the crank is the issue. Either take one of your spare crank pulleys get the v cut off the outside and machined with four bolt holes centered up and put together or get an adapter plate cnc for it.
Essentially the belt Lully was machined off in a lathe, a step put in it to help centre the new pulley and drilled and tapped.
You'll also need to think about you're belt tensioner you need to keep tension on these belts to make them whine!
You will need to use a 320 belt..
