64 Dart GT (273) Vert--Let the Bolt-ons Begin!

I can see the sence in upgrading to discs, however...I've driven plenty of cars with only drum brakes and never had an issue...hell that's all we had "in the day"....62 Chevy 409 4sp, 65 GTO 389 tri-power 4 sp, 64 Chevelle 327 4 sp, 47 Ford Coupe 427 4 sp, all cars with drum brakes and a little more grunt then a 273 and all stopped just fine.
