I’ve had 4 CF Vettes 3 84s and the 82 we have now all have been great and very reliable.
With that said, some of the things that can be done are, up the fuel pressure to 14 lbs, change to an after market coil & ignition module, TPI fuel pump and comp cams CF grind cam, or 1.6 rockers.
Good luck Steve

If you go with headers make sure you still have the O2 sensor. It is needed for the computer. Also you can remove all the A.I.R. stuff since the headers will not have the air tubes. The Crossfire Vault site is great, but they tend to go for the high HP mods, not so much the everyday driving. But it's still worth checking it out, they are the best at crossfire knowlege. The crossfire has fuel injection, no adjusting them, no jets.
Good luck,
Dave

the po of my 82 out a hyper chip in, which from what i understand, changes the shifting in the trans, changes the mixture of gas/co mixture and a few other things.
have nothing to compare it to, so i don't know if it makes a difference.
also, i have a fuel pump from an 85 in there also.
the po told me these things will make a difference in how it runs.
sorry, thats all i have for you.

shifting difference in terms of what? different speeds, hardness of the change?
i also understand that the chip increases the fuel output at wot, giving you more power.
what does one cost, if you don't mind me asking?

I could not tell a bit of difference to be honest. They sell for ~$125 but I will sell you my Hypertech for $50 if you want to experiment.

The only items I needed to replace were the O2 sensor and the EGR valve....to me it's the most refined C3 and a great cruiser.

My wife and I like the looks of the '80-'82 years more than others. We bought an '80 because it was the last of the non-computerized years and thus easy to upgrade.
I recently posted a few pics in a different thread:

Mine was free. It came in a spare computer some on gave me. The car seems to shift at a higher RPM and it also keeps the car out of closed loop for a longer duration. Ijust finished making my car ram air. I have not had a chance to road test it yet as it is raining like a mother down here. Ill let you know if I notice any differance.

It is the most refined C3 and is a great driver. Also the bad rap is because people dont want to learn how to deal with the cross-fire and the fact that they are not the easist to upgrade. However I have done some research and 64 cc heads, a computer friendly cam, porting the intake, and a good highflow exhaust systemtem will produce 300+ HP with the stock throttle bodies and stock computer. Thats what is in store for me when I do the rebuild of the motor. I already have the 2" exhaust, high flow cat and flow masters installed on the car.
