I don't think it's a lot of money.
Our Club sells the Rollmaster double row timing gears (crank and cam gears);
Vernier adjustable, with the best Iwis pro series German chain, for $AU265
That's about $200 USD.
If you're happy to get it right within a tooth, then you probably still need to
replace your 50 - 60 year old timing gears and timing chain. Which I think will
cost you about the same if they aren't Chinese or Indian.
As John said, once it's bolted up, it's the same.
