You will be fine. Enjoy the build, it should be a something else! You may struggle to find forward bite with all that HP, but you may just have to ease into it off the corners...
My buddy is building a '67 Notchback Cuda with an EFI 360 and Hotchkis suspension. Viper brakes all the way around. A little tamer then your build but a good all around car. I will show him the pics of your car, he will be envious.
