Whats all needed for 3.5 TB?
 

Im finally getting my UIM ported and polished so I can use my 65mm tb off a intrigue. Im getting the adapter plate and cable bracket from WOT. Is there anything else needed? Also getting uim, valve covers, oil pump clamp, thermostat housing powdercoated. And getting the modified heater tube.

Seems like you have it all covered

only thing I can think of is maybe a vacuum line plug for a port on the tb, if you haven't grabbed the TB yet grab the vac line fittings with it from the yard, they have good bends to work with the N-body setup. I also had to extend the black tube from rear valve cover to intake(brain fart on the name of it lol) might not have to with the 3400 but with my LX9 and thickness of adapter plate I had no choice
