If you can fabricate a plenium to fit between the blower and the bottom part of the tunnel ram, it would probably be OK. The plenium should be 2-3" thick. This would allow for the mixture to equalize before it enters each intake runner.

Using a 4-53, 6-53, 8-53 and the B&M(which are all the same basic design) would be very helpful since the rotors are straight. The straight rotors would provide better distribution. The curved rotors(also called helix rotors) of the GMC 71 series cause the fuel distribution issue---but also give better seal/boost to the engine.
