I am swapping out the 305 for a 350in my 83 z28 but it has cross fire injection so it has a computer, since i don't want to spend alot of money for a good fuel injection system I am wondering what to do with the computer and all the wiring if I go with a carb?

 

If at all possible stay with fuel injection. You'll get more power out of the 350 than carbed. You will need to get a new chip for the differences in CI. Go to chevythunder.com & read those articles on these setups. Really good stuff there. I may be doing a V6 to V8 swap soon. I also am seriously considering TPI instead of carb. But time &will tell. Good luck with your project.
