I have off the shelf Rapid Stage 2 LS1 heads and 10.5:1 compression making 480rwhp on my 383. LS6 heads and 11:1 will put you well over 500rwhp on a 383.
Its not that hard to do with the right combo. And I did it with stock wheels, steel driveshaft, belt on and air cleaner in.

that 480rwhp was with sheetz 92 octane and 250 miles on the motor too.

i put mine together but i would buy from MTI, APE, More or one of the other great sponsers.
Mine is all Forged Callies with diamond pistons.
Short blocks assembled are $6k and then you need all the bolt ons plus heads/cam.
I have no regrets and drive mine every day its nice.
