This is only something I am looking into for lighter components.

Aluminum still retains original shape after running its not like they get longer and longer over time
Im not talking about thermal expansion. Im talking physical rod stretch from the rpms youll be spinning. From what little ive read it would appear the consensus is that a steel rod can stretch from .030" to .050" depending on how high you spin, and alum rods stretch an additional .010" to .015" more then the equivalent steel.


Wich means if you figured for your piston to be flush with the top of the block deck once you start spinning high your rods can stretch and start smacking your head.


Im just trying to make sure youve looked into every variable of this engine before putting it together.....i wanna see this thing running just as much as you and everybody else becuase its going to be pretty badass.
