225 /6

I am looking for a RUNNING slant six that was recently (or is about to be) pulled that I can put into my 63 Dart and drive around with while I am rebuilding the original motor. I live in Southern California, and am willing to drive up to 4 hours to come get it. Ideally the motor should be from 67 or earlier, but I am not going to ***** and whine if it isn't. I just need a decent 225 that ran/runs well. Thank you !
