HI
I have an 83 camaro 305 w/5spd. I'm in the middle of replacing intake gasket and want to know if someone can help me w/what I wouldn't need in all the crap that was removed or rerouted and tied back so I could get intake off...4 hours job. Have never messed w/any computerized in an engine bay. I am wanting to replace the carb for non computerized. Any ideas would be appreciated. Only reason I'm looking to replace is because I know nothing about what sensors do what or which wires run what as well as all the little vacum hoses and what not. Would also like to get rid of whatever I can on smog control. The whole reason for wanting to do all of this is to drastically clean up engine bay as well as to understand what I have in there, because with all of it I am lost. Any ideas or help would be appreciated. I know I have to go hei distributor if I do this, so any help in that area....ie what to hook up to new distr. would also be appreciated.
Thanks
Bo

 

If you go to a non-cc setup, you'll need the non-cc carb, and a non-cc distributor. Since you have a 5 speed, that simplifies the torque convertor issue.
So it's not bad.

However, before you did the intake gasket, if it ran ok, then you may want to keep the stuff. You'll get better driveability with that cc setup there.

I'm assuming all your sensors are in place and working? O2 sensor, EGR, whatever else is used on that car? (as you can tell, i've got rid of my cc setup, but for somewhat different reasons...)

Where are you located? Smog inspection a problem?

 

I have a '87 firebird, that had a cc Q-jet. I removed it and the computer. You will have to remove the O2 sensor and plug the hole. I suggest a Edelbrock preformer intake and a 600 cfm preformer carb. You will also need an HEI distributor. I have an MSD. It is great but expensive. You might consider Pretronix, GM or Accel. All are cheaper then MSD.

 

Live in kansas, no smog emissions tests as of yet...who knows whats to come lol. Thanks for info...One other ? I have a edelbrock performer rpm intake on a 71 pontiac lemans...will that intake work on 83 305 chevy? I know the early pontiac and late model chevy 350 are different but not sure about the intake. Also what wires would I hook up to non cc HEI distributor?
I have 1 4 wire that plugs into cap and 2 2 wire that plugs into cap in front of the 4 wire. Thanks for all the help guys.

 

The wires that go to the cap are the same between the CC and non-CC distributors, so when you get the non-CC unit, just plug it in.

The intake question was answered in your other post.

You might consider a 6210 Holley. It's a double pumper spreadbore. It will bolt to your stock intake, and would be a good match with your manual transmission. The only hitch is it uses a divorced style choke, which the stock intake won't accommodate.

Oh, yeah - Go Broncos!

 

On the dist. I dont want to plug in the computer though do I? And which one is the computer? And what is a divorce style choke? Sorry but am pretty new to this, so hope you can tolerate. Thanks for info

 

The flat 4-wire connector that comes from the base of the distributor to the firewall is the computer harness. You'll disconnect that when you remove the CC distributor, and can stow the firewall connector out of the way when you put in the non-CC distributor.

A divorced choke just means the choke thermostat isn't mounted on carb itself. The factory had a few different styles, but they all bolted to the intake manifold with a link that went up to the carb.

 

Ok great, on the 4 wire connector. Now there were two 2 wire connectors as well on CC dist. Will I hook both of those back up to non CC dist. or just one. I ordered my parts today and went with the cyclone intake and Holley carb w/electric choke that is jetted for my stock 305...hope it works out well. Again thanks for info. Also I'm leaning towards trying to hook up everything on my emissions control...is that possible without hooking up all the Computer stuff? And if so....is there anything I wouldn't be able to hook up since I'm doing away with CC carb and stock intake?

 

The distributor has 4 connectors - from the base of the distributor to the inner portion of the cap; from the base of the distributor to the firewall; the power (BATT) wire from the firewall to the outer part of the cap; and the tach (TACH) wire from the firewall next to the power wire on the cap. The only one not on the non-CC distributor is the 2nd one.

That Holley is probably a vacuum secondary model. Not the best choice for a manual transmission car. It will work, but you'd be better off with a double pumper, or stick with the q-jet.

The intake probably doesn't have provision for the EGR valve. Other than that, everything should mount back up, but without the signals from the distributor and carb to the ECM, none of the emissions equipment will work as designed except the cat and EFE valve.

 

Ya the holley is a vacum sec. but this is my 15 yr old sons car so I figured it would probably be ok that the secondaries werent kicking in alot lol. If I understand you right the only wire I wont hook up to non cc dist. is the second on you named, from base of dist. to firewall. All the others will hook up and will they have same kind of connections as the CC dist. had? And wont it still help emissions to have the AIR tubes running into exhaust and pump still hooked up?

 

You've got the wiring correct.

I think the default routing for the A.I.R. is the cat, so it would help some to keep it going.

 

Hey, got it all back together and ran ok for 5 min or so while checking for leaks and setting timing and such...started it next day to take it for test drive and was acting like it was flooding out, running rich and died,while checking the choke noticed that it was continuously dripping fuel into secondaries. What would cause this and the sec should not have any fuel at idle should they?

 

The most common cause of that is some debris in the float needle & seat. Very common when first started, as the lines get flushed with fuel, etc.

Do you have the filters behind the inlet nuts? I assume this is a dual inlet carb (I'm trying to figure out from previous posts what type carb you got).

 

No this is not dual inlet. It is a 600 cfm electric choke model 4160 holley vacuum sec. Ah...dumbass me forgot to install the inline filter. Ok what can I do to clean out the debris AFTER I install the inline filter?

 

Take the bowls off, remove the floats and needles, blow/flush things out. Reassemble, readjust.

(4160's come in both dual and single inlet styles.)

 

OK, got the new carb (company sent me a new one....same model) put it on and ran great for a good 2 days. Now all of a sudden it is backfiring through carb. At idle runs great...smooth. 2000 rpm and up backfires big time. Its timed by ear but has to be very close....was running very smooth and starting very ez when hot. Doesnt have a timing mark or indicator since it was a stock CC and I changed out intake, carb, and distributor. Any ideas would be appreciated.
