Motor question...what would you do?

[medicman775]

I need to make a motor decision soon. what would you chose between the 2 choices. I have a fairly built 454 w/aprox 425 to 450 hp...would be carburated till August when I can get a good deal on a FAST or Atomic efi system. The other option is to buy a 6.0 w/ZO6 cam w/aprox 375 hp. This would be a complete motor w/wiring, ecm thottle pedal, etc. I already have the 454. This is going into my 71 1ton burb, running 35" tires and t400 tranny. Need to decide very soon.
