line lock 67 cuda hellllllp

Un-*** the proportioning valve , buy an adjustable and install it on the ( here it comes ) rear line.
Then M/C to line loc to front wheels.
I know there are variations to consider.......this is what I have done for ever on disc front / drum rear cars and it works like a champ.
I used the prop valve on the rears to try and balance the braking based on the much larger foot print the rear tires provide.
I have heard of people using the prop valve on the fronts saying that it keeps the skinnies from locking up , but I prefer to have as much braking as possible from the front wheels. my .02 and you can have it for free.
