Please help with my engine build up.
Here is the deal, I want 10's. I would love to do it N/A but will use the juice if I have to(most likey will). I am going with a 383 and I have to be emissions legal. So right now I am thinking of the cc305 or the cc306(but emissions). I don't have heads yet but will buy the heads that are needed.
Do heads affect emissions in any way?
Everything inside will be Forged so should I go with a nitrous set up or a N/A set up?
Will a Forged N/A set up be able to hold a 100-200 shot?

Forged will be plenty strong-
When you get a car into 10's NA and pass emisions- give me a call. I'll be waiting with a shovel.
Your best best is more nitrous (or well tuned turbo/blower)-
anyway emission and nitrous work a hell of a lot better together than NA- especailly when you start boogieing.
Build a bad *** bottom end. Get a small durration high lift cam I guess- that seems to be all the rave- with a nitrous/blower grind. Spray the **** out of it.
Just my 2 coins. A lot cheaper.

Good points by Trey as usual.
U have to figure out EXACTLY what u want out of ur motor before u start parting it together.
A forged 383 is a nice N/A motor, but not prone to high revving.
If ur getting into motor building, especially in a quest for 10s, ur gonna have throw emissions out the window.
The setup I personally am gonna run is a 355, 4340 SCAT crank, Eagle H-Beam Rods, and some Nitrous pistons, likely SRP. With this kinda of setup, I can rev the hell out of the thing, past 7000 (balanced and blueprinted of course
) Then put a 200 shottie on it and I'm ready to rock.
The Nitrous/Blower cam is a great idea for ur goals... It would cost u a lot of $$$$$ to stay N/A and go with a big N/A cam and some heavily ported heads.

I dont feel the 3.75'' crank is enough to hinder spinning high- or at least that high.
once thing is for sure, more cubes will get you there a lot easier and cheaper.
as with any motor- its all going to be about the heads, cam and tuning right
ps-
7000rpms = pcm issues
be sure to get FAST or DFI...

thanx Trey, I'll keep that in mind.
6700 IS pretty good for a 383, plus ur doing it right
A few guys in my area who have built inferior 383s are only spinning them to 5800-6200.
What are the cause of tuning issues with revving past 7000? I haven't heard that before. I'd appreciate if u would elaborate.
