Hey guys turns out that my stoke 4.6 needs a new piston and sleeve. I am going to just buy a new one and keep the stock one for a back up and fix it overtime. I was looking at 3 different motors the lrp .28 the axial .28 and the picco .28. Right now I am kinda going for the axial or the lrp. Right now I am highly thinking about the axial .28 because it is only $130 shipped. My question is, is it an an easy engine to brake in and tune? That and what does engine modding do for an engine and would it be worth it for me to do to the axial 28?
