    As many of you know, i'm restoring a 74' 455 . I currently run a 350.4 in my 70' skylark. I have gone through the heads from top to bottom.. Stage one heads.(large valves), added stronger springs for the mild cam I'm going with, Had the cylinders bored .030. 74' came with HEI! What kinda differences in power, takeoff, torque, etc. will I notice from 350 to 455....

    Somewhere around 100 more ft/lbs of torque. You'll definately feel it.

    A glove compartment full of clean drawers. You'll need a clean pair every time you put the petal to the metal.
