If you want cheap & easy find the stock intake off of an older Mustang GT. I scored mine, with a bunch of miscelanneous engine parts for $50 and my friend actually has another he wants to get rid of, if you decide to use it.

How old of a Mustang? Maybe an 89 like the one mentioned earlier? The carb I currently have is 2 barrel, would I have to change to 4 to go Mustang?

I'm talking like '83 or so. It's an aluminum 4-barrel intake.

Interesting....the same year as my car. Will I have to modify the TBI system? Or did the Mustang even have that then?

no, the tbi system would go bye bye if you went carb. the tbi (or cfi as ford latter called it) is an early version of fuel injection, replacing the carb with an electronically controlled unit that did the same thing. So that would just go away and you would replace it with a carb.
there is a site out there that has how to revert the cfi to carb, but I don't have the bookmark anymore. You should be able to google it or Eric might have an article at http://www.coolcats.net

If you have CFI right now (ford's name for TBI) then the intake on your car will support the direct bolt-on of a 2-barrel.

I think I need to ask you guys once and for all what a TBI system looks like.....I mean supposedly my car has it but the almighty Chilton manual basically just says it may be in there somewhere. And the fact that this is a Canadian car makes me wonder if it was subject to the same emission laws of the time in which case maybe it really doesn't have the electronic system. Are there telltale signs like around the base of the carburetor...is there a wire leading to a computer control module?

I know quite a few people on here have pics of the CFI body that can help you pinpoint. Just pull the air cleaner off. If you see two injectors with wires leading to them, you have CFI.

Also, if you're talking about an intake for a 351, nevermind what I said about the stang intake or your own stock one, as 302 and 351 intakes are different widths, thus not interchangable.

Don't worry I mean a 302. I was asking earlier if 351 heads would be compatible though. I've had that air cleaner off a few times but I'll go take a really hard look at it later tonight. Though I know the garage replaced the "carburetor" back a while ago. I don't know if they replaced it with something exactly stock or for that matter they may have just yanked the injectors altogether and put on a carb without mentioning it. I guess I'll see what I've got.

well, if you know what a carb looks like, cfi doesn't look like that.
there will be two large injectors with wires coming out of them. and a couple sensors attached to the unit.

But, CFI has a similar apperance, also has 2 barrels, throttle linkage on the side much like a carb. The difference lies within where you see wires attached.

K I'm now leaning towards it being an ordinary carburetor. A yellow wire running into the base almost convinced me it was TBI but when I followed it it turned out to be a vacuum hose. Just to confirm I'm posting these pictures I took.

It's a carb (woohoo!). If you can find an explorer engine, get it and then buy an aftermarket dual plane intake, such as the Edelbrock performer RPM, and a good 4 barrel carb. With the explorer camshaft it should still put out close to 300 horsepower, and you could recoupe the costs of the intake and carb by selling the fuel injection stuff and misc explorer on E-bay. You'd need a new distributor though, one from an 85 Mustang GT 5-speed, or at least a hardened steel gear for your stock distributor would need to be pressed on.

You could just soup up what you have too. The prices may end up costing the same either way.
