Help with possible fuel starvation issue

[Will__L]

prostreet 68 c-10...with a 498 bbc...with 750 dominator...the issue i found is that from a dead stop if i mat the throttle (it just blows the tires off) but if i stay in it after a couple seconds (of blowing the tires off) it will die shut down. The first time i did it, it completely shutoff. The second time i caught it peddled it a few times and saved it from shutting down. If i go from a 20-30 mph roll it will not shut off. I just recently tuned the truck on a friends chassis dyno jetting through the curve is pretty close to perfect. Other than that the truck runs and drives very nicely. I was thinking maybe i need to move to long body main jets or maybe floats are a little low or both? i just found this issue because i never floor it from a dead stop...BTW i was doing this in a safe area...
