With me I have a 1969 Dodge Dart originally had a slant six but now I have a donor 360 that came out of a 3/4 ton van 1988 . Problem is its basicly all junked has rust in the cyclinder walls etc and so with the money of my now wrecked motorcycle I plan on finding another good engine to just basicly tune up and drop in ready to go. Problem is there is th 360 la and the 360 magnum which one is the more I guess you can say better horsepower stock one and what vehicles should I look for in the junkyards. Have cash in hand but not sure of what exactly I'm looking for. Already have oil pan and motor conversion brackets. Please help thanks.
