Swapping in a big block

We are porting the heads and are going to see what they do. I am also working on getting a set of Edelbrock Vic max wedge heads, which will make the power. I have been thinking about doing an aftermarket rear. Subframe connectors are on the list. You don't think the front discs will stop the car? I will be using a dynotech engineering driveshaft. There sure are a lot of naysayers around here. I am looking for some info, not "its gonna cost too much, you can't do this, that won't work" Come on guys, be supportive, not negative. I asked because I have heard of some issues with fitting a 383 in there, I just needed to know what mounts to use. this is not the first car I have built, just the first Mopar. Will I need a dropped centerlink?
