Any idea on what jet settings I should be using on the following - X-flow,1660,gas flowed head,275 cam,lightened,balanced etc carb - 38 DGAS, the problem is that the car runs fine when cold, but when warm a flat spot appears from low revs, when running against compression and then opening the throttle, the car dies , pops and then goes like hell!!! at high revs all is well, problem is that the motor has great low down torque, but I cant use it, so I'm battling to get it sideways out of round abouts!!! - Help
