Took the Barracuda to the track today for first time

OK Guys and Gals, took my total street barracuda to the track today and need some suggestions.

67 Barracuda, 360/904 3.55 rear 3000 convertor .509 cam, headers 3" exhaust dumped at rear axle 3" dynomax mufflers. Stock bottom end running 93 octane pump gas. 750 double pumper Holley, 3/8 fuel pick up and line to carb running Holley blue pump set at 7 psi. Drag radials hooked with no tire spin.

90 degrees 70% humidity.

During entire run there is no missing, noise or surging, no electrical cut in or out. Heres the thing. during burn out engine revs to 6400 very quickly in 1st and 2nd gear. lanched at idle pulled 5500 in first was not making any power past that shifted 2nd and it would barely pull 5000 RPMs it went flat shifted to high for 13.5 @ 100mph.

2nd pass left off idle short shifted at 5000 again it strugled to pull 5000 in 2nd gear and ran 13.46 @ 101mph.

60 ft is 1.89 on both runs I know it needs more gear and convertor but that is the trade off for the street. I am thinking it is not getting the fuel later in the run although it never acts like it is running out of fuel. It pulls smoothly the whole way just struggles to RPM in the middle of the track. ANy suggestions appreciated.
