Thanks Steve for the correction, I'll have to find a new calculator. LOL

Brakes Help
In case you're not Hydroboost or Manual
Since you're at 7", which doesn't seem too low for your giant cam considering, you'll need help with your vacuum brakes.

Leed Brake Vac Pump, in my GN sees 23"
Hella 5.0 in my GTO sees 21" and fast.
Both are plumbed to vacuum canisters, so they don't run constantly, with gauges and have a check valve to engine vacuum in case they fail.

230/236 on a 113 has 7 degrees of overlap. That is quite a bit.
TA would be able to tell you if there should be more vacuum. My guess would be 10"hg
