The Stovebolt Site Forums The Parking Lot Big Bolts changing 1954 mastercyl 2 dual mster cyl options?

Thanks, I figured there would be a change in the mc bore size. Larger bore, move more volume in the same stroke.I wonder how that relates to pressure applied, if at all, larger surface area more psi? Is the bore 1.5 inches on the 1.5 ton and 1.25 on the 3/4 ton?
Reovering from a gass well accident, so I have lots of time to plan this project out.
