The Dodge Challenger Message Board

Any suggestions on what wire harness I can use (engine) to transision from a 318 to a 440? Both engines are date coded 1973. The 440 is from a Charger. Both are A/C / automatic. Can I re-use the original 318 harness? Or would looking into a Charger harness work? (I do not have the harness for the 440) Thank you in advance on any help.

Re-use the 318 harness.

Thanks Dave. That's what I wanted to hear.

Just did this very thing. I agree with Dave. Depending on what Distributor you install, that may be the only real modification necessary.
