Would these fit in the 33?

It is abt 3" high from the centre...
With a balancing valve you only need one and not two separate cyclinders?
Thnx

It would, but it will require some fabrication. 33 is not set up for a direct link to the master reservoir.

Unless, this is installed than the whole mastercylinder can be moved to the engine compartment:

Which would also allow than the installation of a hydroboost... (but then you need a powersteering or electric powerpump.... :rolleyes: )
Things to think about....
In general, space is tight on the Hot Rod and installing a M/C on the firewall may prove a challenge depending on what engine you're planning to use. A good fabricator with some engineering skills can do a lot of things a typical hobbyist may have trouble with. But everything you modify will add cost & time to your build. Myself, I don't see the advantage of using a single dual M/C in place of the two M/C & balance bar setup the car is designed with.
Better look closely at photos of other builds with similar engines and pay attention to the firewall area clearance. Then get a drawing of your selected engine with dimensions so you can lay it out on your car. I suspect you'll find there is limited room for a firewall mounted M/C. And you sure don't want to mount a M/C like that under the dash.
Robert, I was working in the shop today so took a couple of photos. The first shows how much room I have on the firewall once the SBC is in place.

The second photo is of my foot box and pedal layout. I widened my foot box and pushed it forward 4" (or was it 5") and lowered the floor 3" to give me more room. My throttle pedal is as far to the right as possible and my brake pedal is close to where the clutch pedal would be a manual trans car. The brake is operated with the left foot, which is typical for a drag car.

Hope this gives you some ideas that will help you on your build. My suggestion is to stay with the balance bar pedal assembly, it works great. I installed pressure gauges on mine to make it easy to dial in front to rear bias and also it helps with the burnout as press the pedal until I get 800 PSI on the front and then set the line lock.

Thanks for the pictures NAZ and advice...
I think you are right, by the looks of it there just is not the room for it!

Theres certainly room if you wanted to do the fab work... but at what gain?? I believe that a lot of builders get bogged down with changing the program without thinking about the design parameters and interdependencies as established by FFR.
That does NOT make it wrong to customize the hell out of the car and make it how you want, but its very time consuming and doesn't necessarily yield a better end product. Your braking system change wont yield a car that stops harder. It just wont. Line pressure is line pressure.

Whitby makes a kit for firewall mounted power brakes.
https://www.whitbymotorcars.com/product/power-brake-kit-complete/
This shows the kit for the Roadster, but there us a kit specific to the 33 and has been installed in several cars. A simple phone call is all that's needed.
Search the forums for "Whitby Power Brake Kit" and you'll see several, at least one with an LS and a few with a SBF.
