   Hi
   
   Im rebuilding a 455 and i dont know if the old stock pump strong enough to get the full power out of the engine.
   
   Setup is:
   
   455 +030
   Forged pistons
   0.04" Qench
   10.5:1
   TA SE1 Ported Heads
   TA212
   Q-Jet 750cfm
   Fulllength headers 2.5" Crosspipe exhaust
   
   estimated horsepower 440-470
   
   What would you recommend?
   
   Thanks
   
   Robert

   A stage1 pump should be fine. If not, you can go with one of these.
