Induction ?? On A 355hp Crate Motor

Hi guys, I need your help here. I finally found the time to work on one of my own projects . 1988 chevy phantom duelley,it's been in limbo for about 8 yrs now. I have a zz4 355 hp crate motor sittin in my shop (still in crate) beggin to go in this truck. I bought this thing what seems like a hundred years ago for a great $$. In the past i always went wayyy overboard with my projects and they always took too long or cost way too much or both.

My questions are can I run the stock tb with this motor? Is there a manifold that will work? If not what are my options. I really dont want to spend the$$ on a new inj. system.
I would like to keep the computer, o2 sens ect... I plan on running headers+ dual cats. I'm not looking for a drag truck so I'm not trying to wring every bit of hp out of this motor.

What are your thoughts. thanks dave

What was the stock TB on? If it was a 350 you should have no problems. A custom chip programmed per your setup might benefit you but it wont be nessesary. Most manifold makers make a manifold (tounge twister) for the TBI in a variety of power ranges.

Siggy the motor in it now is the stock 5.7 350. The new motor has aluminum heads not sure of the bolt pattern for the manifold. I was hoping that I could find an intake that will go on the new heads and the stock TB will bolt on. I was also concerned the stock TB would be too restrictive or not deliver enough fuel. If this is going to be tough I decided a carb and no computer will have to do

If the stock tbi will bolt on I was planning on having a chip burned for it.

thanks let me know if you have any other ideas.
