Firstly, just chose a displacement already, as I have a 350 on hand, this will be my choice.

Secondly, my expectations and goals for performance... I honestly believe 1RWHP/CI naturally aspirated, streetably, reliably, and on pump gas should be reasonable and within my capability.

So now that that is established I need the forums help.

The most important thing for me to do would be to identify all the components of my core, and then decide what gets replaced and what stays stock right? Correct my logic here if I'm wrong. 350RWHP on a chevy 350 with an auto 4 speed turbo trans to a 12-bolt posi-trac diff (can't remember gearing) is possible on some of the stock internals while staying within my expectations no?

I need to: Identify the heads. The valve train. The current bore shape and weather it needs to be overbored. The piston types. The rod types. The crank type.

Give me more homework here, I'd really like to get the ball rolling.
I would guess you know the 350 can be made into a 383 by a crank and piston change.
The 350 RWHP is about 400 or so at the crank.
By 4-speed do you mean a 700 r4?
If you mean a turbo tranny it is a 350 or 400.
Yes,your 12 bolt will handle 350 RWHP.
Find out your gear ratio.
The casting numbers can be found on the heads under the valve covers.
Stock rods will work fine as long as they are prepped well.
You know that you will get about 25 + ideas of what to do.
