Hey thanks for all the comments guys. From what I understand, I should go with all forged parts. This is what I planned to do after looking here in the past. I understand the crank, rods, cam and heads but I'm not sure in the differences between the pistons.
I am not an engine builder and will be having someone do the work for me. Having said this, a seller of the rotating assembly can lead me down the wrong track in terms of realibility and power. I aggree with ski that I would love to copy someone elses combo but many of the 383 combos in signatures don't often show HP numbers.
Ski mentioned a strong bottom end but the power is in the heads. Do you mean the block as well here in the bottom end? My intention was to use the stock block, get a forged 383 rotating assembly, and get the heads (383 ready) from Bob at Precision Porting. Does this sound acceptable. Note that the car will not see a track (there are none here within a gas tank or two). It will be running from a roll or occasional light to light (until my D36 blows up anyway).

I agree with Mos, Eagle bottom end, and then a good set of heads and a cam to compliment the two. If you get around 330rwhp-350rwhp that is about perfect for the street. Get any more than that and its a waste - a waste in the sense that you can't use it 99% of the time anyways. I don't think I have been able to go past 40% throttle in 1st gear with my car, and past 60% throttle in 2nd or 3rd on th street since I went to the 406 and 434CI motors. If you do they just blow off the tires...so it would be a waste if I did not go to the strip with the car. Hope that makes sense.
I still advise that you try to match another combo that is close to your goals.

Yes, it's really that simple. With all the info here and what's available from reputable vendors you can have a bottom end that should live, if spec'ed for your purposes. Put everything you can afford into the heads, proper cam selection for your needs, etc. and with a good tuner to top it off, you should be very happy when it's done. I'm embarking on a new bottom end project. I couldn't afford the lightweight crank but went with a good forged one from Eagle. With the lightweight Eagle H-beams and lightweight SRP pistons they should be able to knock a little weight off of the crank anyway when it's all balanced. SRPs are a fine piston, the JEs are just a little more serious (for the hardcore racer) and priced so, but for most of our purposes, the SRPs are more than adequate.

Be careful with Scat cranks. They are having a huge batch problem as we speak. Small block chevy 383 and 350 cranks (at least )are affected. 347, 351 and 302 ford cranks are also sharing the problem. The fresh cranks are probably ok. If it is off the shelf, look closely at the thrust flange. It just cost me a motor. Not bashing Scat, decent company. They are just having a few issues.

Hey, that's all good stuff. Glad to head I can use my stock bottom end. I want more than 330-350 though because I would like to have more power when highway speed rolling (ie 70 and hammer it) I don't street race from light to light. It's always the guys that come up on me at highway speeds and want to go.....
