How much improvement will I see?
And if you do want/need to load the converter up a bit prior to the hit, you have to make sure the remaining pump shot (since the throttle is already a bit open) is sufficient to cover the throttle stab. I've found using hole #2 on the pump cams is helpful for this as there is more remaining pump stroke when you do that. You can look at the Holley charts and compare the remaining stroke from various part open throttle positions.
Since I stage mine at 2000 rpm, I had to set the avatar up for that.
