whats the potential gain in building a 350 or upgrading too a 383 sbc

[Grumpy]

keeping everything else the same,when upgrading from a very similar 350 to a 383, the increase in displacement generally results in about a 45 hp/50 ft lb improvement and a peak power point in the rpm band dropping about 400rpm, your 882 heads will be a restriction.
yes youll notice the difference.
youll be amazed at the info in links

you won,t know the answer to how well any combo runs until you do some testing and tuning with that combo, but its very likely that it should function well with minor adjustments, if the parts you select match and are properly installed.
for some reason most guys think that the constant addition of new parts solves most issues, and the truth is that the VAST majority of issues, are due to either mis-matched or improperly installed parts,or lack of tuning experience.
damn few guys ever get their car engines and drive trains functioning at near peak potential performance.

part of the reason the web site exists....its here hopefully allowing the newer guys to avoid many of the problems ,
that my, friends and I ran into, over the decades in this hobby, and hopefully the web site will help you, avoid the frustration ...
and experiences of several of the older guys ,I used to hang out with, had both good and bad, experiences ,
during 45 plus years of not being able to find a easy to access source of correct related info on how things should be done and
how knowing often,my friends and I ran into scammers at local machine shops,
and speed shops, that deliberately either gave B.S. info or did sub-standard machine work.
In this hobby of building cars and modifying drive trains for increased performance, doing your research into how things should be done correctly, is key!
if you get to know an honest machinist in a local machine shop that will take the time to explain ,
how some machine work is done and why its required you'll be far better off.
youll notice most threads have sub-links they are there to help you find related and useful info,
skip reading the links and you will generally regret it later.

[NOT A TA]

I've been working on the 993's for my 357 build.. I have to stop following these links.

I'm repeating to myself "Money goes to the the Firebird now, must not buy aluminum heads..... Money for Firebird, no aluminum heads..... Cash for bird, no alloy heads...." AHAHAHAHA

Then I look at the burb I need to pull the 454 out of and start repeating to myself. "No the 454 can't go in the Malibu now. Cash for bird... No BBC, cash toward bird......"

Yesterday I started to argue with myself "I know it's a passenger block but you can't put it in the Malibu now.... but, but.... NO! Cash for Firebird ONLY now!" AHAHAHAHA

I gotta stop following your links Grumpy.
