silverado carb swap
 
hey I was wondering if there was anyone who could help me out. I have a 1994 silverado with a 350 crate motor in it. Since i bought the truck I have had constant problems with the computer and the fuel injection. So I am planning on switching it over to a carb and ditching the fuel injection for good. So far i have bought a holley 670cfm carb, edelbrock air gap intake, msd hei distributor.

1. If i remove the computer completly will my guages still work or will i have to re-wire them?
2. Will i need to take my fuel pump out of my tank and put either a in line fuel pump or a mechanical pump on it or will i be able to just put a fuel presure regulater on it?

If anyone has any information or anything that would help me out that would be awesome.

I've never done this before. But I have both.
I have a 350 4 bl carb with an Edlebrock intake in my 57 Chev truck
I also have a 350 TBI on a stand in my shop.

That Edlebrock intake won't fit my TBI cause the heads are different.

Compare yours. Insure the bolt pattern is the same and even compare the pitch of the mounting bolts as they thread into the heads.
I'm pretty sure they may be different.
