Distributor Vacuum Advance?

Rat,
So now locking the dist is also a crutch in the Rat Bastid world. So what 'issues' would need to be fixed so that a locked dist is not needed??????????????
You have NO idea. No idea how combustion at idle is affected by extended valve timing events. Among other things.
I could sit here all day & provide examples from engine builders with far more knowledge than you who actually understand what is needed & give their engines the idle timing it likes.
As far as 'trick ponies', I have had more than you will EVER have....
