Well it's smaller then a booster
Yes,Plumcrazy[Kurt] has 2.One on his 62 Impala and he just put one on his 65 C10. Removing the valve cover on his 62 is now easier.It has a solid roller cam in it.The C10 runs a hd.roller cam set up in it,so the only need to remove the covers would be due to a gasket leak.
yes, not that much maybe an inch, inch and a half. But the diameter is smaller and that is what usually interferes with valve cover removal. HOWEVER the performance of a hydro boost is so much better that it would be well worth the extra effort if needed.
I don't sell them but probably should. The red 59 pick up in my avatar has one and it is the best brakes I have ever felt in a old vehicle, all due to the hydro boost.
Kurt says the same thing about his truck.
That is a common issue with non power disc brake retro fits on cars originally built only with drum brakes.The larger volume of fluid required for disc brake operation requires a larger master cylinder bore for a given stroke,which in turn increases the force needed to generate the hydraulic pressure.Cars that were built with both disc or drum brake systems as options typically had different brake pedal assemblies to match the different systems.The placement of the pivot and pushrod attachment points had different center to center measurements to provide more or less force to the master cylinder.
The drum brakes were self energizing and the disc brakes are not. This will also be a reason for the increased pedal effort.
Pedal ratio is key for manual brakes, I set a hot rod with disc font and drum rear and no power booster, To overcome this I used a 7,2:1 pedal ratio, car stopped on a dime and when pushed had plenty of feel.
You're using a 1 1/8" bore master with manual brakes?
You'll never stop with that. That master is for power only, way too big for manual brakes on your car.
You use a 1" bore max for manual with the rod in the upper pedal hole, doesn't matter if 2 or 4 wheel disc brakes.
1 1/8" will be correct with a hydro boost and should go in the lower hole of the pedal

1 1/8" will never work with manual. 1" is perfect, you use in same hole as stock position, You don't change pedal ratio with manual. Pedal ratio is not your problem
