If you've got a dual master cylinder then the answer is yes.

Tried to delete this. I need to look at my car. I modified mine to a dual master cylinder, so my distribution block plumbing might be different.

I've had my line lock installed before the distribution block on my Chevelle for decades. Dual master with power front disc.

All it does is cause the brake light to come on when activated because it's moving the valve in the distribution block and triggering the switch with only the front brakes used. Once I'm done with the burnout and use the brakes again, it centers the valve and the light goes out.

I only did it this way because the lines around the headers were much easier to access at the time, and I've found no real need to dig back into it and start redoing new lines "after" the distribution block.

How about disable the rear brakes for burnout? When I had drums I always pushed thru the front brakes in the burnout box. So I had the lock on the rears so I could stand on the brakes. I recently did a front disc conversion. Can I still put the lock in the rear line with front disc/ rear drum?
