It'll be softer, but it will not be so bad. It will stop good. Not so bad that like its going to be a runaway freight train. I have a solid 314/318 540/585 on a 108icl 112 lobe sep. I drive this SBC 400 on a daily basis in a C10 Blazer with a 6 speed. 3.73 rear eaton limited slip. The pedal is soft but not that bad I'm not running a vacuum canister.
