It'll work, but the jets, metering rods, spring hangers, just about everything will be a far cry from the quadrajet GM would have put on your 305.  Air/fuel ratio won't be perfect, but might be o.k. with a little tuning.  All that stuff can be changed out anyway.

 I put a 305 qjet on a 366 tall deck once... worked beautifully! 5.0 to 6.0 with absolutly nothing done to it aside from adjusting the secondary av.
 Granted a 454 is a fair bit larger.. but depending on the build and the expected rpm you may get away with minimal adjustments...rejetting and so on. Personally I would have already slapped it on and tried... why not?
