Ok so if you know about syncing the transfers
then, in your case you want them to be a MINIMUM of square, to a wee bit taller than wide, and the secondaries should be closed up tight without sticking. You must run a PCV, and the Vacuum advance must run off the sparkport.
That should get you in the ballpark.

Yup. Vac advance is off of spark port.
Secondaries are closed. Factory pcv still on and confirmed working.

It goes like stink, pump shot works good. (Had to change to the holley squirters with the tubes on them) cruises nice. Smog was removed, including air pump.

I'm already at the 750rpm factory setting. So I'll dial it back a bit timing wise to open the plate a bit more.
