Hey all, got a '65 Barracuda with factory 9" drum brakes. Putting a 360 Magnum motor in and I obviously will be needing a brake system upgrade. I've considered SSBC disc brakes for converting, but am not sure what would be best for stopping a 250 hp motor. Heard 4 piston 11" rotors do very well, but the price is not quite in my favor. I also have a 1974 Plymouth Duster /6 car, 10" front drum brakes. Can I use the backing plate, and upper control arm for the conversion over my 9" drums on the '65 'Cuda? I'm taking the 7 1/4 rear end out with 9" drums, and putting in a b-body 8 3/4 489 case - 10" drums. What would also be a good master cylinder set-up for the conversion?

The ssbc kit A153 is excellent non power disc kit. It includes master cyl and is a very complete kit. It offers excellent braking and I have a 320 hp 340. It has both 4 and 4.5 bolt pattern in them and comes with 2 sets of studs. You will have to fab up some new brake lines though. The other thing is you will need at least 14" wheels and not all clear 11" rotor, (14 ralley's do). This is what I have on the 71 Demon and you need 10 spindles for this kit.

If you want to step it up a notch you can run the wilwood kit. This is what I have on my 65 Cuda. Not as complete of a kit but has aluminum hubs for weight savings also needed is 10" spindle. I'm running 17's on this car but you will need 15" wheels minimum.

I use the 153-2 SSBC Kit... Installed it about 12 years ago, and no regrets. Very easy to install if you already have the 10 inch spindles !!!
As Keith said, 14 Ralley's do work, but I prefer the 15 inch Ralley's... Though, my spare to fit in the wheel well is a 14 Ralley! You can't go wrong with either disk brake kit mentioned in this thread !!!

Thanks all for the input! I still need to know if my upper control arm needs to be switched out, and if I can use the 10" spindles off my '74 Duster? Not quite sure what all I have to do to make these disc brakes work/what needs to be changed out besides getting the 10" spindle.

The uppers on your car will be ok. The bigger upper ball Joint was used on the 4.5 bp disk brake cars from 73 up. All A body's upper control arms from 9 or 10 drums are interchangeable.

Will these work with 14" Rallye wheels?
