I am rebuilding a 305 engine and i'm putting the finishing touches on it. I bought a GM Chevrolet chrome air cleaner to sit on top of my throttle body. It has a recessed base. Problem is, it doesnt sit down on the throttle body because it hits on the back left side on that pollution control thingy. Has anyone had this problem or no how to fix it.

Welcome to the boards!

i didnt have a problem with mine hitting that, mine was hitting the throttle cable bracket and i had to cut and modify the bracket, its the AIR(pollution) tubes pretty far away from the air cleaner, or do you mean the EGR valve mounted on the intake?

Oh and i see your from pittsburgh, where about? Im an hour north around new castle.

Delo93

New Castle, sweet, I'm on the north side of pittsburgh. I have family in the new castle area. It is hitting the egr valve.

I got an 89 RS too. The engine had 165,000 on it and was smokin real bad. I got a good deal on a low mileage 305 from a friend so i cleaned it up and swapped everything over from my old engine onto this new one. My air pump was frozen so I'm thinking about scrapping all of my pollution control **** but i'm a little worried about emissions. I was thinking about using aftermarket headers on it and putting a high flow cat w/ a flowmaster or dynamax muffler on it. Kinda need some feedback, but i wanna get this air cleaner problem straightened out first. I'm like really trying to build on a budget so i dont wanna go too crazy.

Cool, I'm originally from Butler.

Headers and full exhaust will help that motor breathe a lot better. You wont fail emissions by removing the AIR pump unless they pop the hood and notice it missing.

Keep in mind 1500 pickups with the same motor had no air pump ...

Will my car pass emissions if I hollow out the cat thats on it now.... still looking for an answer on that air cleaner problem

If yo get collector car/ classic plates for your car you will only have to pay around $100 for the paperwork once and never have to pay registration again as long as you own the car, your car is old enough, i got the plates for mine. Also your insurance will go down alot, and you will be exempt from emmissions! If you plan on keeping the car and not using it for a daily driver i think you should look into it, it might take a month to month and a half but in about a 3 years it will definately pay for itself. I live in an area that doesnt require emmissions but it just makes me feel better that i dont have to worry about it if they do. And if you ever want to get into chip tuning for your car let me know, we might be able to get together some time and do some tuning, if i can get some free time around my racing schedule.

As for the EGR valve, if your going to get rid of the pollution stuff you might have to tune your chip anyway, but if you do just remove the EGR valve and get a block off plate for it, and that will get rid of that problem. Also if you dont have alot into the newer 305, you might want to consider a 350 everything swaps over you would get more power and if your messing with your chip anyway for the pollution stuff it would just take a little more to tune it to the 350, just a thought.

Delo93

Thats the answer I was looking for. So... if i totally remove it, the engine will probably run like garbage until it gets tuned, correct? I just have to make sure I block off the vac line going to it.

As for the 350 swap.... trust me, i'd love to step it up to a 350, I just dont have the $ to be doing that right now, its definetly in the future though. I just wanted to spend as little as possible and have it still look good.

The car is not even close to being ready to drive... i stripped it down to bare metal and everything is off the car. Car is currently sitting in primer and its been that way for over a year now. I just bought a house last year and was working on that this past summer. This summer, all cars!!!

xjcamaro89

I hear ya, i went through that house crap last spring and never go to do any of my hobbies last spring and summer. And i get what your saying about the 350, it was just a thought. Anyway, it might not run that bad without the EGR on or the smog stuff, if i can remember right i think i took all that stuff off and blocked off the EGR stuff before i tuned my chip and i think it still ran ok. but ya block off that vaccuum line. And for the classic plates, all you need it 4 color pics of the car (when it wasnt in primer) and fill out the paper work. So if you have 4 color photos of the car before you stripped it and the car looks good and pretty much stock use those, so you can be getting the classic plates while you work on it, the only thing though i think you have to show proof of insurance on it that is up to date, and you might not have insurance on it since it has been sitting and you not working on it.

Delo93

I dont have pics, the paint was in bad shape when i bought it. Will the car have to be in original colored paint to get a classic plate?

xjcamaro89

No it doesnt have to be original paint cause they have no way of knowing, but i dont think it can be some radical paint color. It just has to look like a car in stock form for the pictures. I had to send new pictures 3 times, first cause i had to take a big chevy box tie decal off my back window cause it wasnt stock, and then the second time cause i tinted my windows pretty much black and they said it wasnt stock so i had to remove the tint and send in new pictures.

I hate to revisit this topic, but I'm putting the finishing touches on this engine, i finally got it in and running. I went to put the air cleaner on but it hits the coil. Do I have the wrong type of base. If so, what kind do I need to get?

Is there a gold spacer ring around the TBI? that's will lift it up enough to clear everything

UnderCover89TBI

iTrader: (25)

to the OP you have a drop base air cleaner so you will have to have the spacer ring as Nagle posted.

Delo93

i have the spacer ring on there, but it still will not clear the coil wire and harnesses.

NagleMac

iTrader: (1)

Thats weird, I guess you're gonna need a raised base, or on with less of a drop

UnderCover89TBI

iTrader: (25)

maybe you have more than a standard drop base? so therefore you'd need multiple spacer rings(kind of crappy)

NagleMac

iTrader: (1)

I have a 14x3 edelbrock pro-flo one, and it clears everything with the spacer on, I got it for $35 at autozone

UnderCover89TBI

iTrader: (25)

yeah but they make air cleaners that drop down 1 inch, 2 inches, etc..yours only looks like 1. the air cleaner has a couple spots that will have more clearance looking at the picture did you rotate it around some to see?

Delo93

well, i bought additional spacer rings for it, now it fits. Kinda sucks but until I get a base that doesnt have as much drop it will have to do.

UnderCover89TBI

iTrader: (25)

Yeah id get the standard base ASAP the double spacer ring limit air entry into tbi unit

92firebird 305

go to summit and order you a flat base element air clean and get the top hat one to more power and more air you you dont have to worry about it touching anything and also get rid of that stupid spacer ring this is what i use with a 4 inch air cleaner with the top hat lid http://www.summitracing.com/parts/sum-239431

92firebird 305

and heres the air lid i use http://www.summitracing.com/parts/SUM-239500/

UnderCover89TBI

iTrader: (25)

they dont sell one with an air lid already? by the time your purchase it like that your entering K&N territory.

Also I purchased my kn extreme flo thru streetsideauto.com for less than 50 bucks than summit or jegs.

92firebird 305

good deal it made a difference on my car thats for sure

Delo93

I got the flat base, but i have to leave the gold spacer ring to clear the coil wires... now my problem is the screw down assembly is not long enough to go through the lid... and on the tbi, the bar is curved, so do they make them longer or what do i do... this is such a stupid issue, and i swear i'm not incompetent

Delo93

i swear it seems this stuff is only happening to me

Ron_90

Screw out the bar just enough so that it's held in there by a grove or two and then loctite it. That should do the job

Delo93

yeah, tried that already, haha... i'll figure something out... might have to fab something, that way I can use my bowtie wingnut on my air cleaner instead of a regular wingnut, the bowtie thread opening is larger

Autozone has extenders for that, they're pretty cheap and that's what i used, it'll take some playing around with but it's not too hard
