440RB INDY DUEL PLANE OR RPM INTAKE HELP

finished the dyno
with 1000cfm carb 600hp over by 5500 rpm and 640 lb/ft peak
holley sniper (rated to 800cfm) 589hp 630 lb/ft
sniper with modified air filter 580 hp 627 lb/ft.
Had to use a spacer to clear some of the sniper for the test so hence why it looks like its sitting up high .
Torque averages were up with the sniper so thats perfect for a cruiser.
I was on the latest super flow that is calibrated every 2 weeks, so this dyno gives no bonuses.
No oil leaks or issues. very happy
The idle quality was noticeably smoother with the sniper.
