I am trying to decide between the kit with the 4.00 stroke crank and the kit with the 4.125 stroke crank. I know the 4.00 stroke crank is much more popular, but why? Does the 4.125 crank not rev as well? What are the downfalls of the longer stroke? I am trying to get as much CI as I can without resleeving my block. Should I settle for the 4.00 stroke? I would like to have a 395 vs 383.
