I have a 1983 with crossfire injection. i bought it without a motor but i have the intake manifold and throttle body and injectors. What other sensors and parts do i need to make it work with another 305c.i. or 350c.i. motor? any help would be appreciated, Thanks, DED.

 

You need to get a wiring diagram for the ECM/engine, and duplicate everything in the diagram. I have a diagram in my Chiltons manual, and another in a Corvette Fuel Injection manual, that should be similar, if not identical. Chilton's is not always 100% accurate. Between the two diagrams you may be able to work it out correctly.

I can scan them and send you copies if you want.

You are aware that the L83 is also known as "Ceasefire" Injection.....
