Need some advice

As much initial as it will take without kicking back the starter when engine is up to temp. Total on sbm is any where from 32-38, but most end up around 34 or so. Need to have all timing in between 2000-3000, get it in as fast as possible without pinging. This is all done with out vacuum advance also. That can be tuned in after initial and total is done. My 340 is at 18 initial with 34 total, all in at 2800rpm, no vacum advance.
