What is a realistic dollar amount for building a street/strip C4? I have a 69' c4, going behind a turbo 302, with a max HP in the 525 area. I'm also wanting to do a transbrake for strip use. I'm currently running a tremec 3550. I'm basically in the dark with automatics. I know the basic mods, converter, servo, input shaft, planetary, valve body, clutch/rebuilt kit, and pedal swap. Just wondering the nickel and dime items.
