Track prep was PERFECT. SBC 6-71 with 2 demon carbs, 295/65/15 ET Drag radials, 4200 stall FTI 9" converter. Footbraked to 2500 and matted it. Car dead hooked and hiked the front then shut off. Front came down I wacked the throttle two more times and engine restarted and continued. Short shifted and finished run with no misfire and did not lay over. It completely ran out of fuel as soon as the front end came up. My buddy at BLP was there and said he has seen it before on sideways mounted carbs. He is sending my 4 sidecut floats to fix the problem. I am posting this in hope I can help someone else. Car never does this on the street because it spins a little. But it DOES try to shut off on sharp turns sometimes. G-force does some weird stuff to fuel systems.
