I prefer the 350 but the 4.0 is a good engine too..to me personally,putting money into a 4 cylinder is just a waste
Really??? I never expected that response from you...lol
Anyway, if you are considering a V8 swap or any of the swaps you mentioned you re going to need to address the rear axle. The D35 does not hold up well with bigger tires and more power. I would go V8. The time and money involved with any swap will come out about the same so you might as well get the most bang for the buck.
