Your photo of your clean clean CLEAN lines and such sparked another question of mine...
Folks running hydroboost units... What kind of pedal ratio are you using? Are they dash hung pedals? What are your caliper types? I've started a spreadsheet to calculate my caliper volume, Master cyl volume, and my anticipated pedal throw based on available mounting locations but some real world experience often goes a lot further than numbers.
I know rule of thumb is 4:1 - 6:1 or something like that. I don't want to end up with a pedal so hard that my wife can't drive it which I know is often a plague of Hydroboost trucks. The designers put too large a bore MC for the volume of the calipers and you end up with a high and hard pedal.
So far my setup intended is '79 Ford F-350 twin piston calipers up front, '75 Chevy K20 calipers in the rear, and a 1-5/16" bore MC with hydroboost that is honestly out of a Clark forklift, but also interchanges with a late K30 chevy truck. 1/4" diameter monel hard lines with short as possible SS braided drop lines.
