Crossfire injection. Is it worth it if its free?

[Guest Anonymous]

I won't bore evryone with teh long story, but I have in my possesion an 82 Corvette that runs, but needs bodywork. It has a 350 SB that has Crossfire Injection. Is this as much of a pain to use and tune as I hear? The car is mechaniclly sound so its a perfect donor for any Chevy parts that were floating around n 82. I guess the question is, if you got a free CFI small block, would you use it?

 

Is it possible to chuck the CFI system and use EFI? Or even a Carb?

 

Can't find much in the Search about this.

A small block checvy's a small block chevy as long as your talking pre-86. Any available small-block EFI or carb/intake setup should work just fine with it. Now if you're asking about emission's legality, that depends on your local laws.

Doing a crossfire conversion is no more difficult than a TBI or TPI conversion. The problem with the crossfire is the wet flow long runners have trouble with fuel falling out of suspension as well as higher rpm air flow. It is an excellent setup for a Jeep or other offroader. I use to refer to my L-83 ('84 Corvette) as the ultimate tow truck motor. Free is free. Swapping the intake for a carbed setup would allow you to move the power range up. One thing about a used crossfire motor is chances are it hasn't been over-revved! BTW, if you wan to sell the rear end, I need a complete disc brake trailing arm setup to convert my drum brake '64 to discs. I'd be willing to buy front setup as well if price was right. (I've got one set already, but hey, spares can't hurt!)

I plan on pillaging as much of this car as I can. I would keep in tact and drive it, but I'm not a big fan of the body lines of this car. Is it that much harder to swap in a fuel injected motor as opposed toa carbed? Is it a different JTR Book, or is it the same? For some reason I thought there was two books and not just one.

Take a look at this thread that was running here just a short while ago if you are interested in what can be done to a crossfire engine. There is a link within this thread where a guy did an unbelievable amount of work to a crossfire manifold to change the performance characteristics.

You can do a ton of work and make it flow at higher rpms, but you seemed more like a cheap guy like me! I like the '82 cars a lot, but they are so expensive, if you need just a little work done, you'd be far and away ahead buying a car in good shape. JTR sells a GM TPI/TBI fuel injection swappers guide that is as useful as the Z conversion book. If nothing else, the crossfire should woul look neat in the Z!

Nothing wrong with being cheap. My datsun is in fine shape, as for the vette, It's missing a passengers door, and it was rear ended at about 8 miles an hour. It rides fine, but the Z has all its body parts.
