I may have asked this in the past so pardon my ignorance or is it just I forgot to take Ginko Biloba today? I found a 82 in really nice shape. Not a fan of the HP rating or the Crossfire design. Has anyone ever attempted to swap the Crossfire for a carbruated crate? Any opinions?
The engine itself does not make any difference. Use the original or a crate.
You will need to remove the crossfire intake. Install a intake for a carb. Connect the fuel line to the carb with a pressure regulator, and feed the regulator return to the original return line. The crossfire uses 10 to 14 lbs of fuel pressure. Most carbs only use 3 to 6 psi. 14 psi might make it flood. If you want you could change the unit in the gas tank and install a mechanical fuel pump on the engine. The present fuel pump is an electric inside the tank.
Then install a vacuum advance HEI distributor, and connect a ported vacuum from you new carb to the vac advance on the dist. The original dist is computer timing advance.
Disconnect the computer, and you're done.
This car will not pass emission testing, and it's breaking federal tampering laws.
If you don't need testing, it's likely you will never be caught and no one will care. It depends on where you are.
When it's over 25 years old it won't matter anymore, except in California.

Thanks, Suppose I just replace the current engine with a crate. Seems like a good option. Any thoughts? Alos, I can register my car as a collectors vehicle and bypass the emissions testing.
No different for a crate engine. Just put it together the same way.
In Ohio you could get collector plates. I'm not sure about other states.

Are there any issues with computer control of the tranny?
In an automatic the lock up torque convertor won't work without the computer. If you have a 3 speed this is no problem, jsut a slight fuel mileage loss. If you have a 4 speed overdrive it becomes an issue. You don't want to operate the car in overdrive without the converter locked up. So either keep it in drive 3, or install a switch to lock the converter when in overdrive. If you have stick, there is no problems at all.

Got it. Thanks for yout help. 

Sorry for the dumb questions. I've recently driven a number of C3's and one thing sticks out. All of them have had a sloppy feel to the steering. Cars drifted, some to greater degrees than others, some had a good degree of play in the steering wheel. Is this a common thread with C3's or did I just drive a few cars that had steering problems?
