70 Cuda' Hemi Build

[ttmott]

I've been a member for some time but I think this my first post.
Anyhow, I've got this 1970 Plymouth Cuda' in work. I had Roush build an all aluminum 557 Gen 2 Hemi with a World Block and Stage V heads and valve train, Oliver rods, Roush billet pistons, Eagle Crank. Holley Dominator EFI Twin Turbocharged with Water to Air intercooling.
I'm just wrapping up the engine install and systems then moving to the back of the car then body, electrical, and final assembly.
Suspension is revamped to coil over front and rear with 15 inch Wilood's and 4-Link with Watts linkage in back.
The objective is an OEM look, quiet running, and track days...
So, I've got some questions on some things for ideas and experience that I'll post in the appropriate areas if you'd be so kind to help out.
