What to do?
Need opinions....
Should I go for a 383 or a 355 when I do my rebuild? All internals will be forged and comp. set to 9.3. I will keep my other mods (se sign) and probably add a ATI 9psi kit in the future (I hope....).
What kind of power will I make with just the 383/355 without a ATI.
Is it possible to hande the power I will get from a SC 383.
Tha car is a daily driven....

I'd go with the 383, its just as streetable of an engine as is the 350 and 355 and it will make more power.
