Whats my best choice for a pull out motor,doable in a weekend and not something out of the ordinary.Im going to be on a budget so cheaper the better,but as well most bang for the buck!....I know ,everybody says 6.0 but...I want to keep my mileage and 6.0s dont like to rev like the 5.3.Ive had great service from my current motor and im thinkin about just going back with the same with a bigger cam.I should have the money in a few months so give me some ideas.I dont have time for my truck to be down for a rebuild so its gotta be a swap.
