[Healeys] timing chain

[Chris Dimmock]

Here in Australia, many of us use Australian made Rollmaster timing  
gear sets, which are vernier adjustable.
They are rated to 10,000 rpm, and 325 lb seat pressure
Rollmaster uses iwis chains (website english.iwis.com ) which are  
German made chains, used by BMW and Opel etc.
The rollmaster vernier adjustable gear kit for a Healey 3000 is part  
number CS8220 and includes iwis chain 3DR62-2 which is a 62 link chain  
which is also used on Holden - AMC V8s and Toyota 18r engines. The  
chains are available seperately 3DR62-2.
Rollmaster also makes a non vernier adjustable timing gear & chain  
set, which has multiple adjustment keyways in the crank gear, but I  
don't have the part number for that one handy.
Best
Chris
