My friend has a 650 Speed Demon on his new 392 stroker from FMS. He loves it. I agree that mechanical DP is the way to go hands down. I am running the 650 Race Demon on my 450hp 351W and I love it. The Demons wet flow above 700 cfm . You will not need more than that for the street. At WOT the mid-range to 6000 rpm will snap you back. My chip is set at 6200 ...peak HP at 6000 with the 650 Race Demon. You should not need much more air flow than @ 6200....and we really only visit that rpm for a brief moment.
