360 swap into 65 Valiant ( Need source for oil pan and pickup)
Once installed, turn the steering thru its limits slowly, looking for interference of linkage with oil pan. I understand you will have to dent the pan to clear on one side. Your 65 273 pan should have a factory depression there, and of course it only fits a 318 or 340, not your 360 which has a larger rear hump.
