Ian , I started with the AMT '57 Chrysler 300 kit . My original post is on page 9 or 10 of On The Workbench , dated April 2 . It will answer most of your questions .
As for the 'cuda parts being 1/24 scale , the difference is less noticeable on smaller parts . With large parts like bodies , the size difference is obvious . Engines are usually almost the same size . Wheels and tires are only slightly larger . Think 16 " instead of 15 " diameters . Again , not really noticeable .
