Likely 383 swap-parts advice requested

Hey y'all, I'm in the process of buying a 383/727 from another member and would like to drop it in my '72 Scamp. It'll probably be taken down and blasted so I can fix up some body issues too. Some other notables would be swapping in an 8 3/4 with 323 SG (staying with rear drums for now) and swapping on some KH front discs. I like the look of the stock ralley wheels for right now, but I might swap to Mustang Bullitt wheels later as I'll have a full spare set eventually.

This is gonna be a bit of a slow moving process, and I'll likely post up changes/progress to my "not really a restoration" thread. I guess I put this up here to solicit some advice on what parts would work well for a cruiser reliable enough to drive everyday. The car will retain a/c, p/s but will have manual brakes.

I'm already running 2.5" duals with an X pipe, so apart from headers/manifolds, I really shouldn't need much there. I know I'll need a new disc brake m/c and proportioning valve for my front disc swap. Also debating which front sway bar kit to use...I've heard the Addco is a pos, but I'd like some folks to weigh in nonetheless.

Any fruitful advice is welcome...

I'd like about 350-400hp and I'm sure that's more than do-able with a well tuned 383. I'm not looking to tear the skins off every time I take off from a stop light, but a good performer all the same.
Just pointing this out but Mustang wheels use a 5x4.5 bolt pattern, the K-H brakes are SBP of 5x4. You could convert to the BBP of 5x4.5 front brakes, sell the K-H brakes and still have money left over. Just saying.
