Advice about a 331 with forced induction

[3MTA3]

Hey all
i just have a few short things to ask:
I would like to stroke my stock block 302 with a kit capable of supporting like 850hp. thats not my goal but i would like to to be able to handle it. i'm not sure what manufacturer is best to go with, and what types of parts. I heard different things for the type of crank and rods such as a 4430 or 2618 forged crank and h beam rods but dont really know what that means. also i would like to bore the block .040 over. will this be a problem when stroking it as well. in the future i would like to bolt up a turbo, i know i need low compression but not sure what i should go with for the stroker kit parts. I've heard about eagle and coast high performance and most say dont go with eagle cause they are weak. i am lookin to spend about 1600 on a stroker kit. i would like all forged pistons and crank. is this possible for that budget?. Right now my engine just has bolt ons, edlebrock rpm heads and an e303 cam. will the cam be good for forced induction as well? my goal is like 700hp. allthough i am new at building engines and plan on putting it all together myself. so far i have done well with my engine. Oh she only has 30,000mi on her so i dont think wear and tear will be a problem. Any advice for me would greatly be appreciated.
