[Fot] Ignition System Preferences?

[Tony Drews]

For my TR-4, I'm pretty sure I used Jeff at Advanced Distributors
http://advanceddistributors.mybisi.com/products/distributors

After discussion with him, he built a Lucas 
distributor package that used points and a Bosch 
blue coil.  He's very specific about the parts 
used, and while the spark isn't as accurate as 
the crankfire setup I replaced, I'm extremely 
happy with it.  Got a spare points plate so it's 
a quick swap if I have an issue.  Runs to 7k rpm 
just fine (although I generally shift sooner than that).

Regards, Tony Drews
