Welcome!! Deer hunting is the high of highs and the low of lows, I never see or shoot "the deer" I'm after but always seem to have a great season. My only advise would be to shoot what you want, don't let others opinions or experiences dictate what you want to do.
I don't enjoy working on vehicles anymore so I'm going with the one below that would last 20 years! To the OP, you cant go wrong with the ford straight 6 from back then...tough motor.
