That's just about what I would build for my 427 Street Kirkham, if I had bought one. No hood scoop, no roll bar, etc. Seriously, that's a beauty. If that car ever gets painted, then IMO, a crime will have been committed.
Do you plan to install the hoop around the grill opening?
IIRC, didn't the street cars come either with or without the
oil cooler opening at the bottom?
Also, let's see a pic of the rear and interior too.
