Which carb would you get?

After finding a couple of problems with the Holley 3310 750cfm carb I have now. I have come to the conclusion that I should either rebuild it or buy a new carb. Here are the specs on my setup.

360, .040 over
KB pistons, final compression 10.5 to 1
Magnum heads, 2.02 valves, ported to the max
M1 dual plane intake
Holley 3310 750cfm vaccumn secondary's
1" carb spacer
MSD Ignition, 6AL, Blaster 2 coil, 8534 Dist.
Comp cams Magnum 280H, 1.6 rockers, total lift .512
Dynamax ceramic headers, 1 5/8 primaries to 2 1/2" X-pipe, flowmaster 40's
TCI 2800 stall convertor
Fresh 727, reverse manual valve body, B&M Megashifter
4:10's in 8 3/4
SS springs, 002/003
26" M/T Sportsman Pro's
American Racing Outlaw 1 wheels, 15x8 rear, 14x6 front

What would you do and why?
