    No one makes this car anymore. The government won't allow them, normal people won't buy them. So it's up to us: the freaks, the weirdos, the informed. To buy them, to appreciate them, and most importantly, to drive them.

      Springs are more dependent on the cam choice, so obviously an agressive cam will need stiffer springs.
      i was going to say that, stiffer springs are a cam tracking issue with a cam with faster ramps and higher lift. not so much a rpm thing.

      did i mention that my mega squirt is working now.......:D

        Ignore the part where i blow my head gasket, pressurize my cooling system, and cover myself in coolant (no hood).

              I like the 3.73.

              I'd probably do a 3.46 if they were easier to get a hold of.
