Yeah, you're right. My intention was to distinguish an all-metal mount from a solid urethane mount (which would still allow some movement). Anyway, the fender cutout has me less worried than the header tube coming off the exhaust port closest to the viewer. Looks like minimal clearance between that and the inner fender. It's probably fine, the builder knows what they're doing from the looks of the rest of the car :)
Yeah, that's pretty valid. Later (73 or 74+, as I recall) Bs have the inner fender kinda wallowed out there (commonized with the factory BGT V8), making a V8 swap easier. Later Bs also have the radiator moved forward, making it even easier. I'm surprised he didn't "modify" the inner fender there. Probably IS tight.
My lowered 77 only had about a quarter-inch between the oil pan and crossmember, and stock mounts managed that OK, so maybe it's fine.
