Seems like everytime you post about your future setup, the amount of boost you're planning to run goes up.

Better put an 80E in that truck...

Which transmission is behind it? And the ring wear on 140,000 mile motor with hyperjunk pistons is good! She should enjoy 10psi.. rear end and tranny are gonna hate that though.. especially a 10bolt rear! kiss that goodbye!
