using a ls6 clutch.

This car was turbo charged with 317 heads but going to be sold as a NA car.

Default looking for the rest

Hi,
i have one of your ls2 ported red intake manifolds with the injectors and rail,They are take offs on one of your motors.
It is going on a forged ls6 bottom,prc 5.3 stage 2.5 heads, ported 08 z06 90mm Throttle body.This is for a 2004 z06.
I have two new USCAR or EV6(EV6_LOTOF8) ls2 injector harnesses,I am not sure but i think i'll have to cut to install them?Adapter??
I need to get an adapter for the TB wire harness and the ls1 map extension or an adapter for other style map sensor?.Is there a product for pvc /valve cover vent?
Or do i use a catch can?I have a few options.

Motivaperformance will be tuning this set up via RRTT on my dyno here in Mobile Al.
