The Crank/Rods/Pistons/Flexplate will need to be balanced, Externally or Internally.
You can buy a complete Rotating Assembly prebalanced = Crank/Rods/Pistons/Pins/Rings/Bearings/Flexplate.
I've heard that you should have the assembly balanced even if it's bought prebalanced; true?
With the TKO 600 at the strip, it seems like the gears will be too long on the top end compared to the 500, what kind of quarter mile time difference would I be looking between these 2?
And what mods does it take to drop weight off the 600?
