Which pushrods are you guys running?
Thickness: (5/16", 3/8", 1/2")
Ball: (5/16" ball size)
Wall: (.080 - .120)
Material: (4140 or 4130)
How much growth are you guys seeing on an all aluminum motor?
- Set Hot lash is .016 and .018
- Once it cools, Cold lash is <.003 and .003 exhaust
- Intake has just the slightest amount of lash
Do you use any special lube on the pushrods to prevent wear
Any helpful hints are great!
