Ok my 496 has been running for about 2 weeks. And have kinda beat a dead horse here on the boards, but one last time.

When i started it up for the first time i had the initial timing to 12. Well after driving the car it seemed sluggish, especially since i knew what it is capable of. So i up'd the timing and was trying to make it detonate, and then go back a few degrees. So around 22 initial timing the motor ran like it should, and ran hard. So obviously my timing tab was put on wrong.

So now the motor runs really well, except when i go to floor the car. There is a slight hesitaion then the motor opens up like it should. I have heard that with to much timing a motor will fall on its face.....but i dont think that is the case here.

496
11:1
294 - 540/560 Retro-roller
Pro TopLine Heads 2.25/1.94
Demon 850 Mechanical
Single Plan Hurricane
Angus roller 1.7's

The only other thing i can think of is that i am sucking the bowls dry, and my fuel pump isnt keeping up.....can the motor drain those bowls that fast?...i mean this hestitation is measured in nano-seconds......Or do i just have some more carb tweaking to do?

Thanks fellas
