340 engine wire harness compatible

[Widedafuhopen]

What's up guys new to the forum, I have a 1973 dodge challenger that I am rebuilding with my pops  . I finally after years of bugging him got him to give me his 440 six pack that has been sitting in his garage for about 20 years lol.  I currently have a 340 four barrel in my car. will the 340 wire harness work with the 440?

I tried to search  around but haven't had any luck finding the info. Thanks I appreciate the help guys!!

You'll have to modify the harness quite a bit do to the opposite location of the distributor. New harnesses are available pretty reasonable.

is that all just the distributor location? I can splice new wires to extend it to the back nicely hidden. don't really have $600 for a harness.

Yes you can splice up your old harness no problem, the two engines are wired the same just different locations of things like the coil, distributor etc...
New harness is about $165-$175.... http://www.ebay.com/itm/ELECTRONIC-383-440-ENGINE-HARNESS-72-73-CUDA-CHALLENGER-72-charger-roadrunner-/151675284077?hash=item23508d2a6d&vxp=mtr EBay is your friend
