newbie wanting input

i have a 87 camaro that i bought from the scrapyard. it is a v6 but we pulled a 350 out of a 80's model truck and are going to be swapping them out. now mainly because i don't want to fool with electronics and computer i will be going carb instead of keeping the fuel injection. so i am always looking around craigslist and i ran across this. i am just not as knowledgeable on what i am doing so does this look like it is what i need to get started. and since this is a 2 barrel carb will i need a new intake if i move to a 4 barrel later or can i keep the same intake and just swap out the carb?

Re: newbie wanting input

You'll need a 4bbl intake when you swap to a 4bbl carb.

Re: newbie wanting input

Since you are posting an Austin CL ad, I'll assume your in Austin, or close by.

FYI.....
If you put a carb on your car, it'll fail inspections. Meaning it won't pass inspections or be street legal.

Even if your making a track car, that 76 intake would not fit you 87 heads. The center bolts for the intake are at the wrong angle. You need an intake that fits center bolt heads.

well thanks for the info on the bolts. i actually got the 350 motor out of an 80's model chevy pickup truck. i could kick myself in the rear for not writing down the info on the truck so i could easily look up parts. my 87 motor that is in there is a 6 cyl. i won't be keeping it. i will probably have my mom register it in bell county she lives in salado. keep it registered there for the next three years then i can put it over here in Williamson county and it won't need emissions testing.

Re: newbie wanting input

Inspections aren't about emissions. That is a separate issue only for a few counties.

An FI car converted over to carb will not pass ANYWHERE, legally. You, you can find a shady inspector (who is willing to risk losing his license for a few extra bucks & give you a sticker), or an inspector who just doesn't care (and still risks his license) who will give you a sticker.

NOWHERE will you find a legal way to get an inspection sticker on a street car.

Some people just don't care & skirt around the law. But even if they get stickers? They aren't LEGAL stickers.

Not even with antique plates nor the 23 year mark for testing, can you get around the visual part.

how about this to think about. You are allowed to swap an engine that was available in your car of the same year or newer, so 87-92. The lg4 was still available in 87 right? so technically you can swap that carbed engine in. Nobody will know if it has 305 inches or 350.

however, you would have to have all the emission equipment for the lg4 installed in the car to pass.

how about that?

You can legally put a carbureted 350 in an '87 chassis. It will have to be a computer controlled carb and ignition, with all of the accompanying emissions equipment that came on an '87 b-body.

Interesting. CC carbs that late?



In that case, yes BUT.......

It cannot be what is typically thought of as a "carb'd" engine. In that.....There is no ECM & is a purely mechanical device, which the cc carbs aren't.

And while you could use a F-body CC carb'd engine, you could not use a truck engine, due to the different federal emissions standards for those two chassis.

In the end though.....What do I care? It's not my car, its not my wallet that has to pay any fines. I'm just passing on info.

Maybe in CO, but not in TX. The chassis emissions requirements are different & you'd fail, just on the engine alone, regardless of the emissions output.

Re: newbie wanting input

so what the **** are yall telling me. if i put that motor that i already bought i will not be able to get an inspection sticker put on it? that is a real bummer. i was so looking foward to putting a v8 in there and now it sounds like keeping the v6 that it in there is going to be the easiest thing to do. i was lookin at this intake

http://austin.craigslist.org/pts/1654229311.html

but if i can't put a carb on it and be able to drive it on the street than it isn't worth even having. i don't go to the track so putting together a car that i can't drive where i want seems like a total waste of money.

Re: newbie wanting input

I think it will be specific to the area you live in. When I did inspections here in PA, it was only visual. The emissions needed to match the car and engine CLAIMED. If you claimed a 305 TBI, but it was avctually a 406 hiding in there...who cares. It just needs all of the emissions crap for the 305 TBI. You could also get a special exemption for installing a motor from another vehicle, but that is a big pain and not worth it in your case. Set up the 350 to match the emissions requirements for a 1987 carbed 305. But please, check with your local requirements first to make sure it is the same as I am explaining.

If they don't allow that, they are being more strict than Federal requirements, which only California is allowed to do.

Technically, no, because the standards are different for passenger cars and trucks.
