Now that 30 years have passed and loads of data from boosted 4v's has been collected along with advancements in tuning, is 450whp still considered the safe limit on a stock bottom end? Also, are 3v rods any different than 4v? it seems the 3v guys say the limit is 500whp.
I even see some mention 450tq, which would make hp way above 500 on a centrifugal.
