special rods like that will cost close to 1k. i don't really think much is to be gained with doing the long rod setup in your application. the 292 is not a high reving motor, ussually 5k rpm or less. there is a rpm spot that causes lots of bad harmonics that occurs close to 5200-5400. can't explain all the reasons why, but it is the big stroke and long crank that cause it. tom
