Well I never put mines in and from what I can tell it doesnt need it. My fan still works perfectly fine without the sensor in it. Maybe its jsut a backup sensor. But I left mines off and its been fine thus far. I still need to properly time the engine and install the y-pipe. I actually drove the car around a bit today. Rides rough cause of the timing. So I will be trying to fix it tomorrow. The swap itself was really straight forward and easy. For being my first swap it has been very successful IMO. Also a vid of it on the first start up. Ive put the hood back on the car now.

 

It's been covered in the coolant sensors thread...
Read my posts above...

 

Ok I thought Id post a lil update on the car since Ive now started on the bodywork. I eliminated the antenna on the car. I will be installing a windsheild mount antenna later if I feel the need for one.

 

Didn't mean to take so long, but the dizzy is boxed. I need an address so I can figure shipping. No, I don't have any bolts. In fact, the dizzy is the only part of the old upper end parts that I have left as I got rid of the rest a couple days ago.

BTW, your doors used to look just like mine... Black over red over other crap. Got both doors stripped over the last 2 days and am getting ready for the rest.

 

Ah sorry I didnt hear a reply for awhile so I ended up switching to the new ignition and well now Im gonna need my 3.4 parts including the oil pump drive. Gonna be using the 3.4 intake aswell as the ignition. Im just waiting for my new ECM from bl85c and im ready to roll. So sorry again man. I have gotten a lot more body work done ont he car however. Stripped the paint off the doors and painted the doors. Used paint stripper and a paint removing wheel. Worked great and got it down to metal. Still a couple spots that need a tiny bid of filler. Also I decided to say screw the hood since its damaged to the point its not worth me fixing. Going to get a fiberglass one later on and decided to prime it just to match the rest of my car. Pics from today.

 

Ok so I decided Im going to do a carb swap on my 3.4 at this point. I dont really care about my gas mileage that much and I want the ease of using a carb. My father and his mechanic friends know more about carb than FI. I am having too many problems with my MFI and am sick and tired of spending money on my car and not driving it. So now what I want to know is what is all needed to do a carb swap. I plan on making a list to hit up the junkyard and store this weekend since i have time. So far I know I need a carb intake manifold for the engine from a 2.8 S10 or older camaro/firebird. Does anyone know any aftermarket carbs that fit directly on the stock intake that is mechanical control? Also what is the best way to regulate the fuel pressure? Id like to not have to drop the tank if possible, but I will if it comes down to it.

 

There are also aftermarket intakes I believe, though oddly enough, Idk of any aftermarket carbs made for our engines, though I think all carbs have the same bolt pattern? Other than carb and intake you will need to switch to a vacuum advance dizzy if removing ECU, which I am assuming you are, there probably is a way to keep the electric fuel pump, but I'm not sure what it entails, the other option is removing it, and putting in a mechanical inline pump. Also you might have to switch throttle and TV cables or bracket, but I think that is pretty much everything.
Btw you're going to confuse the hell out of that car if you keep putting firebird parts on it.

 

Well im hitting up the wrecking yard tomorrow. Maybe I can find me an old S10 I can grab the carb and intake off of aswell as the dizzy. I plan on totally eliminating the electronics system as it has given me nothing but a ton of trouble for the past 6 months. Also because this is my weekend toy I dont really drive it everyday and dont need it to be reliable or fuel efficient as a FI system would be. Plus carbs look cool IMO under the hood especially with all the wiring eliminated. Anyone else have a recommendation for a carb for these engines? I heard you can take an older s10 carb intake and drill and tap new holes for a diff carb. And yes my car is very confuzzled, but the pop up headlights sucked bad and were too expensive the replace and I wrecked part of the front bumper. I techincally still have all the parts to make it a firebird again.

 

Wait its a firebird with camaro parts o.O? I thought it was the other way around...well I rest my case then, lol....confused me even..Is the only thing you swapped the front clip, fenders and hood? Cause from the outside thats a pretty damn convincing "camaro". If that thing ever goes to a shop someone's going to do a real double take when they look at a paper or the VIN and read firebird and look up at what appears to be a camaro, lol.

 

Yup its a firebird with a camaro front clip. The fenders, front bumper and hood are camaro. The rest is firebird/trans am. I added a trans am rear bumper and gfx to match the front camaro gfx.

After doing more research fro the past 3 hours Im a little bit confused now. I understand the older camaros/firebirds witht he 2.8 had a carb but were computer controlled. What does the computer control exactly? From what I can tell its just the advance for the timing and nothing else. If this is true can I use a old camaro/friebird carb and just eliminate the electronic advance by using a vacuum dizzy?

 

I believe those were "quadrajet" carbs or something like that, if you search you might be able to find the answer, I honestly don't know what the ECU would control in a carb since I don't know what the carb controls other than fuel and air, maybe it controls AFR?

 

Ok so scratch that, apparently your right it controls the air and fuel ratio. So it will run rich without the computer. I talked to an S10 buddy of mines and he says the S10s and blazers dont have a computer controlled carb on 85 and back. So maybe tomorrow ill get lucky and score everything I need.

 

You'll never find any GM distributor for your engine that doesn't need a computer to control the timing. Such a thing doesn't exist, never has. Also, the pre-'85 Carburetors are all computer-controlled. You have to use Edelbrock's intake to use a non-computer Holley 390 carb, and buying the Holley and Edelbrock parts new will cost more than a used SBC swap.
Either fix the EFI, or do a different engine entirely.

 

I beg to differ, I actually found a dizzy that will work.

Correct. The early genI 2.8 engines have the old HEI distributors with vacuum advance and weights. I believe it's 79-84 or something like that that have them.

You can get a 4-barrel carb intake from Edelbrock that fits the 2.8. It's a 2-piece manifold, however. Anything found on a factory engine has a 2-barrel carb or similar TBI unit. The Edelbrock intake is the ONLY aftermarket intake for the 60* V6.

 

Well for costs sake right now Im gonna hit the junkyard and try to find a varajet 2SE carb and S10 intake manifold with a dizzy. I plan on going with the eldebrock later when funds permit. From what I researched the 2SE varajet should work fine and will allow me to remove the ECM all together. The E2SE is the one found on camaros and firebirds but have an electronic ignition control.

 

Okay, order that AutoLine D2100 and see if it's non-computer. If so, then Edelbrock needs to note this.

 

It's an older coil-in-cap dizzy with 4 wire connections in the cap... BAT, TACH, module battery, module coil ground. The module has 4 terminals on it, 2 pickups, power, and ground to the coil. If it has vacuum advance and advance weights, there's no ECM to advance the spark timing.
