Extremely high, hard pedal with a 1.125" bore unit and not a lot of brake torque due to low caliper pressures. Very bad idea unless you're running a hydroboost IMO.

I wouldn't recommend running the Wilwood #260-8555 1" bore MC with the LS1 F-body calipers unless you were running a vacuum booster, especially when considering the factory LS1 F-body setup is a 1" bore MC with a dual-9" diaphragm booster. A 15/16" bore unit (no Wilwood option that I know of unless you move to a dual MC setup) will net you about 12% more pressure and pedal travel over a 1" bore unit, 7/8" bore MC (#260-9349) will be about a 25% difference.

Pad compound counts for a lot, especially when running manual brakes, so it would help to know what you intend to run for pads.
