Under stock cover or a Milodon set up? They sell gear drives that are quiet but if your going to go with a chain I recommend a cloyes true double roller timing set. Cam button is not a bad idea. Is this a race motor? Pete Jackson sells a quiet gear drive that fits under stock timing chain cover that has a duel idler system.

It's under the stock cover, probably an eBay special, lol. Doesn't matter, it's leaving and timing chain going in. I have a double roller set, it's a 1 bolt but I don't know what the cam is 1 or 3. So I'll order a 3 bolt so it's here when I get it apart.
they were meant to whine , a gear drive was a "must have " item on 80's street machines

So whats the brand of the gear drive?
I've been told Rollmaster is a top notch set up also. Good luck 
Red Label Premium and Gold Label Extra Premium Timing Sets:
All Red Label timing sets are produced using billet steel for both the crank and camshaft sprockets. The grades of materials used are mentioned further down this page. Gold Label sets are nitride hardened and include a one-piece Torrington and Iwis chain. Red label sets come with 7 or 9 crankshaft keyway sprockets depending on crankshaft diameter. The smaller shafts tend to be best suited to 7 crank keyways, although engines like Small Block Chevs etc come with 9 so it allows more adjustment for dialing in the cam. Crankshaft sprocket keyways are in 2 degree increments always unless otherwise noted. The relationship from crank keyway to camshaft sprocket timing is 2:1 meaning that the amount of advance or retard at the camshaft is in one degree increments, IE 1, 2, 3 or 4 degrees. Multiple keyways are a solid fixture and do not tend to move or work loose like offset dowels, thus providing a positive locking of the cam timing to whatever position is desired. Rollmaster timing sets are light weight and stronger than any other timing set available due to the weight savings of billet steel and CNC machinery. No additional machining is required to fit these sets or the need for offset bushings or drilling of cam gears. All Red Label timing sets come standard with Rollmasterʼs own premium grade Iwis full roller timing chain. Every small and big block Chev comes standard with a brass thrust washer and is available with an optional one-piece Torrington thrust bearing. You will find Rollmaster has included brass thrust washers to most of our range including Ford for increased performance and reliability. Where possible our one-piece Torrington thrust bearings can be applied to most of our range of timing sets and listings are noted accordingly in our catalogue. Notice our Nitrate hardened timing sets and those fitted with one-piece Torringtonʼs, compared to the standard billet steel sets. All Timing Chain Sets are made from billet steel, have 9 Keyways (unless otherwise stated) and have a heat treated crank sprocket. Red Series: standard billet steel set with induction hardened crank gear Gold Series: premium billet steel set with all sprockets nitrided for better durability and longer life. Line Bore Kits available in .002", .005", .008" and .010". When ordering Line Bore Kits mark order with LB2, LB5, LB8, LB10 after the part number. When installing any new timing componentry we recommend using a degree wheel to set perfect timing.

I figured the same thing, this is a really good chain set with lots of perk's, so I install the timing set to degree in my cam and as i'm spinning the motor over with a breaker bar i see the chain go slack then tight then slack then tight.... I put a dial indicator on the cam sprocket and to my surprise it was out of round by 0.14 thousandths. called RollMaster and they sent me a new one. good customer service ,Could you imagine the poor bastard that never noticed offa!! anyway its a good chain for a high performance build.the moral of this story is check, check, and check again ...I've been told Rollmaster is a top notch set up also. Good luck

Be aware that you may be able to here the solid lifters after the gear drive is gone

The Gear Drive is going to be a 3 bolt, so you'll obviously need a 3 bolt timing chain setup.
I had a gear drive on my 440, and man I hated it. I replaced it last winter and I'm so much happier. I can actually hear the engine.
