Yeah the 5.0 they put in those cars could take a lot of abuse. Mine was a 1992 which was the last year of forged pistons stock. The engine had about 137k of really hard miles before I decided to build the 347. I built the 347 from a new aluminum block and gave the stock engine, which still ran well, to a friend. The car was originally an automatic because I was trying to find one in that color combo that had never been wrecked. I found it about 500+ miles away from me. When I built the 347 I destroyed the original AOD even after I had built it up. That is when i converted it to a manual and put in a Tremec TKO500.
Your 2010 looks good and you definitely put it through its paces. Unfortunately right now I am just driving around a jeep and I am about to buy a house so it will be probably another year or two until I can get another stang.
I sold my fox to buy my fiance' an engagement ring... At least when it comes time for me to buy another the new 5.0L will be out.
