Crossfire fuel injection converted to Carberator?

I believe the Crossfire fuel injection can be converted into a carberator. However I dont know where to find this sort of conversion kit, or how much it may cost. I would like for my 84' vette to have a carb because of the ease of maintence and I also plan on adding some performance parts. Speaking of which, any suggestions on where to start for basic performance. It already has flowmasters. I would like to start with the basic engine components, then maybe even a supercharger. Thanks for the suggestions.

I think you will have hood clearance problems if you don't have the right intake someone may have more on this. I did this on one with parts that we had laying around and we had to cut the hood and install a low IT1 type scoop. Supercharger? Disregard All Of Above just cut the hole! A 671 type charger will really block your view in that style Vet ,just a thought to ponder.

I would strongly consier staying fueld injected. I have a 70 mustang and dropped a fuel injected engine into it, it was pretty much hell getting it to go in nicely so i converted it back to carbureted, witch cost me a little under a thousand, if i could do it all over i would not have converted back, but here is the parts your probably going to need to get.

New intake manifold around 150 dollars

4 bbl carburetor talking about 300 for a good one

inline fuel pump running 7 psi 100 dollars

new throttle assembly to carburetor

new distibutor because the one on there currently is probably an electonic one. Your looking at around 200 for that plus ignigtion box, youll still be able to use your old coik pack your just going to have to do some wiring.

So all and all i would stick with fueld injection because it is a headache to convert back because you have to retime your engine and tune your carb. with fuel injected you get much better gas milage and you can even hook your laptop up to your computer and see what is going wrong with your car, and tune it if your really into racing.

let me know how it goes and if you have any questions ill be around later

I still think that a carburetor has more potential than fuel injection. The crossfire fuel injection is certainly not a state of the art fuel injection. If I get it to a normal chevy 350, I can start tweaking it the way you would for a muscle car, because, I dont drive it everyday and emissions is not an issue. I want some serious performance now and in the future, and I think that fuel injection will limit that.

I still use the xfire intake with bored tbi's and a 7747 reprogrammed computer on my '84.The thing I would worry about would be all the digital dash stuff. .....Jay

Well if your talking serious performance, then go for it man a good set up can make some serious horsepower, but fuel injection does have some of its strengths, but since you are not going to be driving it alought i wouldnt worry about the gas milage. The only bad thing about fuel injection is when you start putting major performance parts on, and a bigger cam the computer will freak out becuase the reading will be all wrong so you have to go to a performance shop to have the computer reprogrammed, other then that i like fueld injection good throttle responce and is alought more efficient.

If you must go to a carb, replace the distributor with a vacum advance , HEI type, (found on small blocks from about 1980 to 83 or in JEGs or other aftermarket catalogs for around $150.00.) Add 12 volts and you have all the spark you need and replace what fuel system you have with a simple intake with a carb and you're down the road. Performance wise, you may be better off to work with what you have, but if you really want a carb setup, which was the question, this formula is the simple way to do it:
HEI/Vacum adv Distributor + carb =good running sbc.

Hope this helps.
