TBI to carb conversion?
I would like to know about converting from TBI to carb. Other than intake, carb, and dizzy, what hard parts would be required and what is the general procedure for this swap?
Truck: 1990 Chevy. 350 TBI - 700-R4
The truck has a slew of bolt ons, + cam (crane2030) and ported heads, Bored .060 .
Please share with me anything you would be kind enough to share

You will also need a return style fuel pressure regulator or a fuel pump designed for a carb.

There is an excellent technical article on how to perform this conversion. It's one of the top articles on the list, definitely check it out. I'm also in the process of converting from TBI to carb.

Re: TBI to carb conversion?
got the fuel injectors off... after i took this pic i cleaned off that manifold as best i could, as you can see its pretty nasty, stuff all over it. anyways, after that i removed the manifold, and when i took my foot off the front end, the car shifted, and part of an acorn fell from somewhere, directly into the #3 port. i couldn't believe it, a hole in one. anyways, i rigged up a piece of 3/4" plastic tube to the end of a vacuum cleaner and was able to get it out of there, and then i vacuumed the other ports just to make sure nothing fell in there... they were clean. as soon as i get the new manifold i will post some more pics.

Re: TBI to carb conversion?
also... i'm not totally familiar with all of the un-necessary items (when switching to carbed), any chance anyone could point out in this picture what i don't need and can remove? thank you very much, everyone here has been extremely helpful so far.

It's linked in the "welcome to the carburetor forum" sticky in the top section of this forum.
