72 Swinger Project

Talked with two Mopar nuts on the phone. Both said the 340 V8 will work. Only issue will be extending the wire to the distributor since the one I am buying is for SB. No such thing as a plug in to the existing harness BB for a 72. I want to drive the car by spring and I don't have the time or the money to rewire the whole car right now. It can wait....unless like everything else...it doesn't work, then replacement will be sooner.
