Purchased new in '18 from SC&C as part of a complete suspension package, including tubular a arms that also lowered the car. Our iron head, iron block 427 sat a little low with these, headers hit the garage floor coming in, so changed to a set with no drop from stock. Ride level looked wicked, but just a little too much for us. Probably fine with a small block, LS1, or stock A arms, can't say for sure, your taste.
Car was never driven on these, and installed for less than a year as we put the rest of the car back together.
