    325 whp at 5500 rpm. 10 psi. Could not get a full run. Fuel pressure dropped at 5500 rpm. Changing fuel system to dual 044 pumps.

    Ran 13.22 with a 2.68 60 @ 121.44 mph. Still stock auto box. That was on 10 psi an 80 deg out. Converter is to tight, wont build boost off the line.. any advice would be appreciated.
