Boost prepping RB Holley carb?

Quoted from 7club-

The reason you lock the timing on a first gen dizzy blowthrough is the fact that the dizzy will NOT retard the timing under boost. At 10-15 psi under full boost you would only need a maximum timing of 5-10 degrees. So you lock the timing to where you would need the it at full boost.

That's just leading timing, and actually you lock it so it doesn't advance timing while the engine is under boost.

Trailing timing and split is obviously a source of contention among people. Everyone has a preference and an idea of what is safe. If that's what allegedly works, then go with that.

why would you believe anything you read on the 7 club? anybody with knowledge has been banned from there!

no, wrong. you lock/ weld the distributors centrifugal weights so as the engine revs up the timing dosnt advance.
why would mazda retard the timing on an n/a car?

lock the dist. set your timing at 10 degrees advance and your done.

That is basically what I posted from the 7club, you just stated it differently.
