Ok so I have a 92 s10 with the 4.3 cpi and I'm really tired of the fuel injection problems I've had with this thing. I know it has a leak somewhere in the plenum just haven't had much time or luck finding junkyard parts (because new the stuff is like $400 total locally) and I would really like to put a carb on it and be done with the efi. I have a 98 blazer also so this will not be a daily driver just a bit of fun. Now I am not a mechanic but I am mechanically inclined and have done all work on my cars myself and like to think that I know what Im doing for the most part but I've never done anything like this before so I'm seeking a bit of guidance. I believe I will need to change the fuel pump and get a fuel pressure regulator but the main problem I'm having is finding a manifold that will work because the ones from '86 say they are for carbs but I cant find one anywhere that will convert from a 92. Any help and/or advice would be much appreciated.

 

You can use one for a z coded engine, just need to trim the splatter shield on balance shaft. Seen a post on here, or somewhere about ti. do a google search.
