RODS... Aluminum vs Steel

[don felton <airtanker2000@yahoo.com>]

Hi All,
  I'm building a new (370") S/B Motor for the old Roadster.
  Trying to decide which type of Rods to use.
  All I have ever used is Aluminum. Nice and light.
  The Steel rods made of 4340 seem to run a 100-150 or so grams heaver than 
Aluminum.
  How does the weight effect running the Long and Short course' ?
  Any helpful advise would be appreciated.
  Thanks a bunch,
  Don
