Members with 4 wheel disc systems: Can you lock your wheels?

Just asking;
how big is your engine? and what cam is in it? and what is her vacuum at 1200 rpm or so?
And what size tires are on the back versus on the front?
Was this car an original 6-cylinder car? I think Six banger cars had different pedal ratios; I think maybe so did DB cars. Not sure which was which.
Does the throttle snap closed to idle at around 750 rpm and does the engine display good engine-braking. What I'm getting at, is the brakes are for stopping the car, Not slowing the engine down.
