Hi all, I did do a search on this subject..so I think I have it pretty well covered. But I still have a question (or two). When I take off the CCC and put on the non-CCC, I'll have to replace the distributor, right? Can any one recomend a good carb and vacuum advance distributor (I can get an old Q-jet, but I don't really want to use that)? Can I take the wiring out out the engine bay and leave the ECM in to control the tranny lock up? Will I have to disect the harness to get the tranny wires out? I think thats all the questions I have now. TIA

Edit: Oh, this is on a 85 LG4 Camaro

 

I'll ask a really retarded question first: Why are you doing this?

 

I was replacing the fuel filter, and cross threaded the pipe that goes out side of it. It did tighten with my fingers, but it still cross threaded. It leakes fuel really bad. So instead of fixing/replacing the Q-jet with another one. I'll take the oportunity to upgrade. Plus I plan on swapping to a 350 soon, and it just so happens that this motor doesn't have a carb on it right now.

 

What exactly was damaged - the "pipe", meaning fuel line; or the "fitting" that goes into the carb housing; or the carb body itself?

Replacing the carb because you twisted the fuel line makes absolutely no sense - just repair or replace the line. The fuel line/filter fitting is easy enough to find and replace. If you mean the housing was damaged, you can get a slightly oversized, self-tapping fitting to go into the carb housing (the carb should be cleaned after you do this to keep debris out of the needle/seat).

What you are proposing is not an upgrade. The CC q-jet is fine for performance applications, including 350's. Putting a non-CC carb on either engine will net a zero HP increase. Go to the magazine articles on this board and look for a couple by Steve Green with "Stroke in the Desert", or something like that. He built a 383 and used the CC q-jet.

What your engine needs to perform is a dual-snorkel air cleaner, a real exhaust system (headers, 3" y-pipe and 3" on back to the muffler), and a real cam. Same for a 350.

That's not my opinion, those are the facts. If you insist on going through with this, then most any HEI will work, from a junkyard or a new or refurbished item from Summit/Jegs.

 

It's been a few years ago, but I helped a buddy of mine rebuild the 305 in his 85 Z28. As it turned out, the cam was too much, and the timing was all out of wack. We went to Auto Zone and bought a non cc carb and distributor to remedy the problem. That setup is still on his car today. What we did was take the wire going to the distributor and just tied it out of the way and we did not experience any problems with the lock-up converter, or anything like that. We just pulled the bulb out of the check engine light and he has lived happily ever after. But that was on his car. Too much compression and cam for the ecm and the only other option was to change the cam. But if youre going to pull the cc carb and distributor, I would leave the wiring in the engine bay. The carb he used was looked up in the Auto Zone computer as a carb to fit a 78 Camaro with a 305. Quadrajet. I know those carbs get a bad rap, but I would recomend using the Q-jet, but like five 7 kid said, even if you goto a holley or other carb, you will be just as well off to put a cc carb back on it and save yourself some money on the whole deal. A cheaper route would be to get a chip for the ecm than to replace the carb and distributor.

 

It's the carb body its self. The first 3/8" of thread are ruined. THe fitting that holds the filter in, is a little messed up too.

 

The $10 repair fitting will take care of both problems.

Non-CC is really a backwards, over-kill solution to a rather simple problem.

 

I'll just answer the original question. Yeah you're going to need a Vacuum Advance Distributor and if you go square bore you'll need an adaptor plate. You'll probably also need a new fuel line, and if you have an auto you might want to get something to manually lock-up the converter.

 

If the computer is still hooked up, and the only thing missing is the cc carb and distributor, the converter will still lock up.

 

and

Thank you. Thats what I needed to know.
