i dont know if this is the correct forum but here goes im working on a restomod 70 mach 1. ive found a two motors (1)5.0 from a late 80s mustang, its all stock with an automatic trans and un known miles (2)5.0 with gt 40 heads from an explorer with 30,000 no trans. i may buy both because they are so cheap. but are there specific year mustang 5.0s that are better or even some from other vehicles. by i mean horsepower and durability, i dont have a lot to spend and i plan on driving the crap out of it.
