Pros and cons about a 302 engine?
Well, I own a 1983 fod crown vic, a 1985 mercury grand marquis, and a 1989 lincoln town car, all with 302 engines, so I think I can tell you something about these ford engines. They should give you anywhere from 15 to 18 mpg, and turning on the a/c won't lower your mpg, or affect the power your engine delivers. They do have plenty of power to move the big bulk of car you've got, so I would consider that a pro. A con I may find in that cougar is that it has a carburetor; I have heard that, once they start malfunctioning, it's real hard to get the engine properly working again; I know a guy who owns a 1973 ford ltd, and has spent years buying different carburetors for his car, and they don't fix the problem. All of my cars are fuel injected, so I can't really tell you about carbs from personal experience. If the cougar's in good working condition, you shouldn't worry about that yet, just take care of the car. It has also been my experience that it's hard to get these engines to overheat (not that you want them to); my cars have never overheated, and, once my crown vic leaked a lot of water, but I didn't know about it until I got home; I drove about 70 miles like that, with the a/c, and it still didn't overheat. They are unlikely to leave you stranded, that's if you give them proper maintanance, not that they need much. I can't find any more cons, and one more pro is that these big v8 engines are built to last, if you take care of it, you won't put much wear and tear on the cylinder rings and all that internal stuff. Overall, the big fords, mercurys, and lincolns are exceptional cars, the exterior can go to pieces, but the engines keep running (if you take care of the rest of the car, it should last a lot too). Well, I hope this helps :)
How can a fuel injection engine change to a carburetor?
It depends on the engine and it's more common to go from carburetor to fuel injection not the other direction. On some engines you would still have an ECU for spark and timing control or the transmission. On other engines it's relatively straight forward.The lower intake has to be changed for one with a place to mount a carburetor. On some throttle body fuel injection setups you can swap one for the other without changing the intake. In most cases a different manifold is required.The fuel pressure for fuel injection is higher 40+psi, a low pressure pump is ideal and a fuel pressure regulator for carb level psi around 5psi. Is needed. The fuel rails or fuel lines need changed at least for the last few feet.The ignition system needs to no longer be computer controlled. That might mean an MSD style ignition box or just a coil and distributor swap, it depends on the engine and what it originally had.Your ignition and computer are probably the hardest parts, getting the engine to fire up again might take some extra effort.Air, fuel and spark will all need some attention. Going from carb to throttle body fuel injection is more common lately and it might be less effort to upgrade your fuel injection from stock to something better instead of going to a carb.On a small block Ford or Chevy it's really pretty easy to convert and probably -$1000 especially if you use used parts you could probably convert for under $500.Finding out what your car needs to start without an ECU or how to confuse it to be able to start is something you'll have to look up for the specific engine/car in question.On some engines the conversion is probably impossible without fabricating an intake manifold. Others, you can find the parts on Craigslist or the junkyard and it might only take an afternoon or two.
