Any updated replies from the people that went with the 7" booster conversion,how well of a stopping performance do you have with the 7" booster on a panic stop?

Dual action booster and front disk upgrade

I have been followng past posts on the booster upgrade conversion for some years now, always thinking of changing mine to a dual booster front disk conversion.

With these past existing posts I know of the panther conversion project and with that I feel that a 7" dual booster is just not enough for a panic or hard stop on a 4,500lb. Car.
With more cars and people walking on the road today I am wanting to do and upgraded braking system.

I currently have my motor out and thinking of doing an up high firewall mount with an 11" dual action booster.I can get away with this mount fitting and leaving my air vent intact and having the straight 8 leaving some pedal fabrication and thats ok.

Also with the front disk conversion I do know there are kits out there for a price but, does anyone know of any common domestic autos that can be used weather slightly fabricated or not. I once talked with an old packard guy with his 56 executive that swapped out with a 1970's Ford Bronco with leaving only a slight difference in the king pin to be milled.
I can no longer find him to ask...

I am only doing this swap for one of a few reasons; as our population and clutterness grows everyday around us i feel it is needed for improved stopping, easier access I am not going for any original points on the car but I'd like for it to be around in the family for another 60 years....
Any inputs are welcome....
