Start of a chassis ..
The real car has a Ray Braton built 604 ci hemi , 5 stage drysump system and no nitrious . Using a Revell 426 hemi block, will change some things like adding a remote water pump so I can model an exposed timing gear and chain, saw this on a Dave S build in the 'Big Boys' section and thought it was really cool.
Some ref. pics, all from commercial sites...
