I know Arrow built these as good as any engine builder out there - they just did not know MOPAR made a mistake - they used the valve which was identifed to go in the heads - stock size for a Gen IV viper engine - The TI sheet was submitted to NHRA after the engine building started - the valves used were appearently incorrectly measured by MOPAR engineering - used a blue print to figure out how to do it - LMFAO

You can't assume anything is right. You have to measure. Do you think that Arrow rolled the cam and checked every lobe to make sure the lift is right? I bet Don Little or Bruce Parsons or Bub Whitaker would have. Do you think they poured all the runners or every combustion chamber? Did they weigh a piston and rod assembly? All of us have to play by these rules. So Chrysler gets to change the spec after the fact. Why doesn't that surprise me.
