Location?

I am going to purchase everything I need for my brakes in the next 3 weeks or so and need to know what you guys think of where I should locate the brake booster and master cylinder? I keep getting some people telling me to put it under the floor and others say on the firewall. This will go on my 48 for those of you that don't know and I plan to put a 454 BBC in it. When you vote, if you can please just add why you think I should put it wherever you voted for me to put it (ie: under floor, firewall).
Thanks for any help.

Floor, easier, less hassle, more room for the big block. you arleady knew my standpoint though.

I would put it under the floor. You can put an access panel with a Dzus fastener in the floor to get at it. If you decide to put it on the firewall, you better have a mockup engine available and installed to make sure you're not putting the brakes where something else needs to go. Under the floor is cleaner too.

My A-bone had it under the floor. My '34 has it on the firewall because it's channelled, and there's no room under the floor. I think you'll find that a suspended brake pedal system is more expensive. Yogi's has a power brake pedal assy for a 48 Chevy for $120, master cyl for $65, and 7" booster for $119.95, two residual pressure valves for $21 each. Total of $347.

Kugel has a firewall mount system for $395, complete with booster and master cylinder. You wouldn't need residual pressure valves with the firewall mount.

Those are just two sources., As you can see, it ain't cheap if you checkbook all the parts.

Thanks guys. Henry, what is that Yogi's site? I never heard of that place before.

How much of a dash do you have? If you have room you can also mount it at a 90 degree angle under the dashboard.

I definitely would try to keep it out of the engine compartment just for the cleaner look.

Pat, there is not much room at all under that dash. I forgot about that one though. But yeah there is basically no room, it's only about 6 inches deep, not even.

@ 6 inches deep, why not have the vacum booster inside the dash and the master cylinder outside? I still think the firewall is the best way to go about this, but ultimatly its your decision. I still have issues with under the floor design, especially if you have roads that are salted or rough roads in general.

Broke a brake line once on an underfloor mount when a rock or some other road trash caught a line off the master cylinder. If you put it under the floor, be sure to fab up a cover to protect it from road stuff.
