Which Slant Six is in it , 198 or 225 ("B" engine code vs. "C" engine code) ?
GA4 ( "Gunmetal" on Dodge , "Winchester Grey" on Plymouth ) is such a beautiful colour . It's truly uncommon ; and it looks beautiful on the Demon .
While I'm personally a fan of the "Leaning Tower of Power" , its presence here is a sore point . A car with a name of "Demon" needs to have at least a small V8 , in my opinion .
But , herein lays the quandary : the car looks way too nice to modify in any way , including engine swaps . But , if you intend for it to remain a family heirloom , then maybe some easily-reversible mods would be okay ( e.g. , wheels / tyres replaced by , say , Ansen Sprints ; and , a careful removal of those garish side mouldings , bagged and saved for later reinstallation if need be ).
Since it looks so incredibly original from its outward appearance , how about taking some extensive photographs of its engine bay , chassis , etc. , etc. , and sharing them with us ?
