I have a 1986 Camaro with a 305 Tuned Port Injection. I am interested in turning it over to a Carburated Engine. I was told I need to get a new intake manifold and the carb. What else do I need and what does this job entail?

 

I have a carbed '84 Z28 and I pulled the ecm completely out. You need a vacuum advance distributor, and you can take out all of the smog crap, although I am not sure if it is legal. I don't even run cats anymore. Mine had been started when I got it, and I just finished up the mess the last guy started. Not sure what all was done before I got my hands on it. There are posts on here that describe what to do. Just do a search and you will find the info.

 

Plenty of posts on here about this, but since I am in the midst of it myself, I'll tell you what I have found so far...

Intake and carb and all associated gaskets
Air cleaner
Distributor (non-computer controlled)
Fuel Pressure regulator and associated hoses, fittings and mounting brackets
TV cable corrector for carb
Possibly a throttle cable (I haven't crossed that hurdle yet)
A way to control TCC (lots of aftermarket and do it yourself solutions)
Keep the temp sensor or your fans wont turn on

I am sure there are other things that I haven't got to yet. It is not as straight forward as the tech article would lead you to believe. For a stock 305, I would get a performer intake and a quadrajet carb and also an HEI.

 

Thanks. Where is this thread everyone is talking about? Can some one post a link please?

 

Look in the "Welcome to the Carburetor Forum" sticky.

Care to share why you are considering this?

 

I'm with five7, I'm curious what your reason is? I'm admittedly guilty of converting to a carb, but that was because I swapped from a V6 to V8. (And it's not a daily driver)

A functioning fuel injection setup is superior to a carburetor in nearly every way on a daily driver, and it won't be emissions legal UNLESS you use a cc Q-jet and distributor, so it's still gotta be computer controlled if that's a concern

 

why bother there wont be any benefit with a stock 305... id just keep the tpi or build a carbed 350

 

Just because I was told that I can get more power out of the Carb, but I have been doing some research and from what people on here are saying it is not a good choice.

Thanks for everyones input though.

 

Yeah don't do it. Fuel injection is the most ideal. And it will give you more power where you need it most (down low).

When someone tells you that you can get more power out of a carb, that is very misleading unless you really know the mechanics. Carburetors are really good at specific power bands. I.E. if you want power down low, then you'd want your primary ventri tubes small to get that air speed up so that the AF/mixture completely atomizes etc.

It's really hard comparing the two unless you have a purpose in mind. If you want a 10 sec car at the drag strip, then go with carb. You'd have a specific power band you'd want to aim for and tuning a carb can get you there fairly easy. But if you want a daily driver, then go with fuel injection. They're turn key and do great at mixing the fuel and air together.

The higher the rpms, the harder it is for FI to keep up. While on the other hand the higher the rpms, the better carbs can keep up with the motor...in a general sense.

Basically I'm trying to convince you to stick with fuel injecting for the street. It's too much work and no point if you're wanting a daily driver with a carb when you have FI already. Personally I'm at that point where I want to get rid of my CC Rochester and put a TPI on my '83.


Hopefully that solidifies your decision.

 

what about fuel pump...can you use the stock one?

 

Yes you can use stock one but you need a return style fuel pressure regulator. I believe Mallory 4309 is one that a lot of ppl on here are usin
