1977 has a carburetor and no computer is this right? I am thinking of swapping the 82 for a 77,any comments from any one? I like th idea of a single carb, and no computer for future rebuilds. All opinions would be appreciated.

Why not just pull the computer crap out of your car?
go with a holley or q-jet, the carb,and distributor are the only two things to change. You will even see a little extra ponies,after the swap. the 77 is a smaller car. Not sure what your looking for,
but don't let little thing's make you change the whole car. I
guess around inspection time you can put the other's back!
-above respondent makes a good point, --unless however you prefer the "flying-butress" roof-styling of the '77; -still if you prefer the '82's styling, don't want to get into modifications, and still want the 200+lb/weight-savings, then opt for an '80 (non-calif. having 1st-computer) Rochester-carb. C3-Vette, --although i believe your '82 has the advantageous 4-speed automatic...

HOLY COW, Sorry i just snapped that you had an 82.
(CROSS FIRE INJECTION) If i am correct, that is a little more complicated to mess with. Do what ever you think would make you feel better. I like the big body vette. . You could always opt
for a TPI unit. Any way, for the price and exchange of car's you could alway's make your's better. So I say really think about what your gonna do.
Bob Chad makes an excellent point about the 77, Q-Jet and no computer, very easy to work on. I happen to like the flat window and smaller size of the 77 and it is also the last year for the 160 MPH speedometer. My car has no emission controls on it what-so- ever, headers and true dual exhaust. I even replaced my stock intake manifold with an Edelbrock Performer 2101 non-EGR aluminum manifold. I don't have to worry about passing an emissions test, only a mechanical, and because it's over 25 yrs. old I am able to have antique auto insurance on it as well.
I have the original Q-jet on my '77. never been rebuilt, never a problem, and runs great. MPG could be better, but it's a hot rod Vette, and a blast to drive. JBW
Hey guys, don't blast the '82 too hard. I've helped people get CrossFires where they belong - with over 300hp. Granted, it's not easy, but you don't have to buy nearly as much (new manifold, new carburetor, etc.) as you'd think. I've already started developing tools to make the tuning process easier, so you could essentially get 20+mpg, and have 300+hp with it.
I really like the body style of my 82, Any help with engine would be appreciated. I drove the 77 last night. It is a nice car, but when you put them side by side my personal preference is the 82 style. If I can get 250-275 hp I would be happy.
Thanks All
250-275hp is easily obtainable, and probably won't even require a computer change.
Port your intake, put headers on and get some good mufflers; you can probably pick up another 30-40hp this way. Also be sure to install a fuel pump from a 1985 Corvette (higher capacity) and 1.6:1 rockers will probably give you enough "oomph" to make you a lot happier.
Anyone read or used the info from "Cross-Fire a-go-go" written by Roy Bohacz, from the April 2000 issue of Corvette Fever? It has a overview (some mentioned by Ken73's post above) of intake, throttle-body, cam shaft , heads and ignition upgrades to produce a realistic goal of 325 hp max from the Cross-fire.
I've been setting aside funds for the project and although I've rebuilt a few engines before, I always like to be on the safe side and ask if anyone has a tip or experience to share before jumping in.
I didn't get a PM that I know of - where do I go to get it? :confused
As for the article by Ray, it doesn't really specify the details of the camshaft - the heart of making it work properly. The real trick with the CrossFire is to use a camshaft with equal intake and exhaust duration/lift. Since the CrossFire has such small runners that are hard to enlarge, it's easier to open the valve longer to get more air/fuel in. A 256H or 262H is a good example.
Of course, porting it goes without saying - I have ported several CrossFires for people and it always makes a difference.
For those who don't know, 'Ken73' is the Administrator of 'The Cross-Fire Forum', devoted to those of us 'blessed' (saddled?) with the Cross-Fire Injected Corvettes. Various aspects of the CFI are discussed, and several members, including a young man in Texas who runs 11s on N2O, have good running Cross-Fires.....
In the fuel tank. It's actually VERY easy to replace - take the fuel door off, take out the rubber gasket, then unplug the assembly and unbolt the top. It literally just twists right out of the back!
That sounds great about the fuel pump...Wish I had known that last summer when I dropped spare tire and the whole fuel tank to get to it from the underside!
Oh well, live and learn...and at least I found the tank build slip in the process.
Anything about wiring or fuel lines I should be aware of when installing the '85 fuel pump to the '82 existing setup?
Installing the '85 pump is pretty straightforward. One of the wires has to be cut and crimped, but it's VERY simple and VERY obvious when you get to that point. Nothing complex about it.
