Need some help on my qradrajet build for my dirt track car.  I race pure stock, 81 monte carlo, 350 stock engine. th350 trans, 4.11 posi, gears.  I got carb number 7044230.  i run 2nd gear the whole way on a 3/8 mile track. i need max. WOT coming out of corners. The quad thats on there now is ok, but stumbles a little coming out of the corners.  Any advise on my rebuild?

Down South:
Have you upgraded the fuel system to improve the flow?

Have you opened up the needle hole in the needle/seat assembly to a larger size such as .130-.135"? Is your float level set to 1/4" below the float well?

for the fuel system, all there is, is a 15 gallon fuel cell in the trunk running straight to the fuel pump, to fuel filter to carb.  and 73 z28, i dk much about these things, i mean i took it apart and i can put a rebuild kit in it but as far a needle in a hole? which one. pics could help, and i havent set the float yet
