I'm running a used $50 aluminum wheel behind a 428 with a Performer RPM cam (very lumpy idle) and I have no complaints. While teaching my 16 year old to drive a stick I told her that in our Cube you step on the gas, then let out the clutch. It the Cobra you let out the clutch, then step on the gas........Not exactly scientific, but it seems to me that lighter is much more better than heavier in our cars. You can quote me on that
Good Luck,
Jon
