Re: basic chevy tbi question

[Hotrodderzzz@aol.com]

Dear Group:

Most of the stuff is way over my head, but I'm getting the 4 layer board 
anyway to start learning for my pet project.  In the meantime, I would 
appreciate any help on the following:

I have a tired stock (tbi)  1990 350 chevy 4x4 automatic.  I have a fresh 400 
sbc shortbock I would like to put in.  I would like to keep it simple (keep 
the tbi and stock computer).  I am looking for torque, probably won't push it 
past 5000 rpm ever.

Can someone help me with the following:

How much flow can I get out of the stock throttle body, how hard is it to 
have the bores bored out, and what about putting "454" injectors in?

Will I need a custom chip?

Can I get enough flow to make it worthwhile to put the vortec heads on 
instead of rebuilding the stock heads?

Any cam recommendations?

Thanks for any help you can give me.  SS
